up1722p/q 4 up1722p/q-ds-f0002, sep. 2016 www.upi-semi.com the up1722 is a high efficiency synchronous-rectified buckconverter with internal power switches. fixed 1.5mhz pwm operation allows possible smallest output ripple and external component size. with high conversion efficiency and small package, the up1722 is ideally suitable for portable devices and usb/pcie-based interface cards where pcb area is especially concerned. with internal low r ds(on) switches, the up1722 is capable of delivering 1.3a peak output current over a wide input voltage range from 2.6v to 5.5v. the output voltage is adjustable from 0.6v/0.5v to v in by a voltage divider. other features include internal soft-start, chip enable, under- voltage, over-temperature and over-current protections. the up1722 is available in space-saving wdfn2x2-6l, tsot23- 5l and sot23-5l packages, in an adjustable version and fixed output voltages. input supply voltage, v in vin pin provides power for the internal control circuit and supplies current to the output voltage. the supply voltage range is from 2.6v to 5.5v. a power on reset (por) continuously monitors the input supply voltage. the por level is typically 2.5v at v in rising. the up1722 draws pulsed current with sharp edges each time the upper switch turns on, resulting in voltage ripples and spikes at supply input. a minimum 1uf ceramic capacitor with shortest pcb trace is highly recommended for bypassing the supply input. chip enable/disable and soft start pulling en pin lower than 0.4v shuts down the up1722 and reduces its quiescent current lower than 1ua. in the shutdown mode, both upper and lower switches are turned off. pulling en pin higher than 1.5v enables the up1722 and initiates the soft start cycle. the up1722 limits the in-rush current at start-up. this prevents unwanted shutdown otherwise may be triggered by voltage drop due to large inrush current. pwm operation the up1722 adopts slope-compensated, current mode pwm control capable of achieving 100% duty cycle. during normal operation, the up1722 operates at pwm mode to regulate output voltage by transferring the power to the output voltage cycle by cycle at a constant 1.5mhz frequency. the up1722 turns on the upper switch at each rising edge of the internal oscillator allowing the inductor functional description current to ramp up linearly. the switch remains on until either the current-limit is tripped or the pwm comparator turns off the switch for regulating output voltage. the upper switch current is sensed, slope compensated and compared with the error amplifier output comp to determine the adequate duty cycle. the fb pin senses output feedback voltage from an external resistive divider. when the load current increases, it causes a slight decrease in the feedback voltage relative to the 0.6v/0.5v reference, which in turn causes the error amplifier output voltage to increase until the average inductor current matches the new load current. low dropout mode the up1722 increases duty cycle to maintain output voltage within its regulation as the supply input drops gradually in the battery-powered applications. the up1722 operates with 100% duty cycle and enters low dropout mode as the supply input approaches the output voltage. this maximizes the battery life. current limit function the up1722 continuously monitors the inductor current for current limit by sensing the voltage drop across the upper switch when it turns on. when the inductor current is higher than current limit threshold (1.5a typical), the current limit function activates and forces the upper switch turning off to limit inductor current cycle by cycle. if the load continuously demands more current than what the up1722 could provide, the up1722 can not regulate the output voltage. eventually under voltage protection will be triggered and shuts down the up1722 if v fb is too low. under voltage protection undervoltage protection is triggered if the output voltage is lower than 17% of its target level and shuts down up1722. the up1722 can only be reset by por of v in or toggling the en pin. output voltage setting and feedback network the output voltage can be set from v ref to v in by a voltage divider as: re f out v 1 r 2r 1r v + = the internal v ref is 0.6v/0.5 with 2.0% accuracy. in real applications, a 22pf feedforward ceramic capacitor is recommended in parallel with r2 for better transient response. the feedforward is internally implemented for the fixed voltage versions. upi confidential

up1722p/q 10 up1722p/q-ds-f0002, sep. 2016 www.upi-semi.com where f osc = operating frequency, c out = output capacitance and ? i c = ? i l = ripple current in the inductor. the ceramic capacitor with low esr value provides the low output ripple and low size profile. connect a 4.7uf ceramic capacitor at output terminal for good performance and place the input and output capacitors as close as possible to the device. using ceramic capacitors higher value, lower cost ceramic capacitors are now available in smaller case sizes. their high ripple current, high voltage rating and low esr make them ideal for switching regulator applications. because the up1722 control loop does not depend on the output capacitors esr for stable operation, ceramic capacitors can be used to achieve very low output ripple and small circuit size. however, care must be taken when these capacitors are used at the input and the output. when a ceramic capacitor is used at the input and the power is supplied by a wall adapter through long wires, a load step at the output can induce ringing at the input, v in . at best, this ringing can couple to the output and be mistaken as loop instability. at worst, a sudden inrush of current through the long wires can potentially cause a voltage spike at v in , large enough to damage the part. when choosing the input and output ceramic capacitors, choose the x5r or x7r dielectric formulations. these dielectrics have the best temperature and voltage characteristics of all the ceramics for a given value and size. thermal considerations in most applications, the up1722 does not dissipate much heat due to its high efficiency. however, overtemperature protection is implemented in case of applications where the up1722 is operating at high ambient temperature. if the junction temperature reaches approximately 150 o c, the otp turns both power switches and let the lx node become high impedance. the up1722 restores to normal operation if the junction temperature drops to 130 o c. it is helpful to analysis the power dissipation of up1722 for avoiding the up1722 from exceeding the maximum junction temperature. in typical applications, the conduction loss dominates the total power loss in up1722. the conduction loss has its maximum at high duty-ratio, low input voltage, and high ambient temperatures. consider the up1722 in dropout mode operation at an input voltage of 2.6v, a load current of 400ma and an ambient temperature of 75 o c. the on-resistance of the upper switch is about 500m ? at this condition. therefore the power dissipation p d is: mw 80 r i p d ) on ( ds 2 out = = this results in 250 x 0.08 = 20 o c temperature raise at junction. the juction temperature is 95 o c and is lower than its maximum rating 125 o c. checking transient response the regulator loop response can be checked by looking at the load transient response. switching regulators take several cycles to respond to a step in load current. when a load step occurs, v out immediately shifts by an amount equal to ( ? i out x esr), where esr is the effective series resistance of c out . ? i out also begins to discharge or charge c out , which generates a feedback error signal. the regulator loop then acts to return v out to its steady state value. during this recovery time, v out can be monitored for overshoot or ringing that would indicate a stability problem. application information upi confidential
