XC6505 series operational explanation the voltage divided by resistors r1 & r2 is compared with the internal reference voltage by the error amplifier. the p-channel mosfet which is connected to the v out pin is then driven by the subsequent output signal. the output voltage at the v out pin is controlled and stabilized by a system of negative feed back. the current limit circuit and short protection circuit operate in relation to the level of output current and heat dissipation. further, the ic?s internal circuitry can be shutdown via the ce pin signal. 6/24 the XC6505 series is able to shut down the regulator circ uit using the ce pin signal. in the shutdown state, the v out pin is pulled down by r1 and r2 to the v ss level. in the XC6505b series, the c l discharge resistance is connected in parallel with r1 and r2 when power is supplied to v in , shortening the time until the v ss level is reached. operation is unstable when the ce pin is open, and thus the v in voltage or the v ss voltage should be input into the ce pin. although the logic is fixed and operation is normal as long the voltage satisfies the ce pin voltage specification, inputting an intermediate voltage may cause the supply current to increase due to the flowthro ugh current in the ic internal circuit. l the XC6505b type is capable of high-speed discharge of the charge that collects on the output capacitor (c l below). this is accomplished by the n-channel mosfet connected between the v out and v ss pins in the block diagram, and takes place when the l-level signal (ic internal circuit shutdown signal) of the ce pin is input. the c l discharge resistance is set to 400 ? (when v = 10.5 v, v in out = 5.0 v typical). the c discharge time is determined by this c discharge resistance and c l l l . letting the time constant of the c discharge resistance r and c l dchg l be ( = c r), the output voltage after discharge by the n-channel mosfet can be obtained from the cr discharge equation below. v= v out(e) e -t/ or = ln v out(e) /v v output voltage after discharge v out(e) output voltage t discharge time auto-discharge resistance r c output capacitor value c ?c l dchg l l the XC6505 series? fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. when the load current reaches the current limit level, the fixe d current limiter circuit operates and output voltage drops. whe n the output pin is short-circuited to the v ss pin, the current falls and reaches about 110ma. the XC6505 series has an internal thermal shutdown (tsd) circuit for protection against overheating. when the junction temperature reac hes the detection temperature, the driver transistor is forcibly turned off. when the junctio n temperature falls to the release temperatur e with the driver transistor still in the off state, the driver transistor turns on (automatic recovery) and restarts regulator operation.
7/24 XC6505 series operational explanation input/output capacitor the XC6505 series uses an output capacitor (c l ) for phase compensation. for this r eason, if a small capacitor or low withstand-voltage capacitor is used for c l , dc bias dependence causes a smaller capacitance value, and phase shifting that results in unstable operation may occur. exercise caution when selecting the capacitor. reco mmended capacitances for the XC6505 series are shown below. for the input capacitor (c in ), select a capacitance of 1.0 f or higher to stabilize the input power. table1 recommended c capacitances l notes on use 1. for temporary, transitional voltage drop or voltage rising phe nomenon, the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, oper ations may become unstable due to noise and/or phase lag depending on output current. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. 3. if the input voltage fluctuates by 1.5 v or more and is at a slope of 0. 1 v/s or more, output voltage undershoot may become more pronounced. in this case, use a larger input capacitor (c in ) or otherwise adjust so that the through rate is less than 0.1 v/s. 4. if a small capacitor is used for the output capacitor (c l below), capacitance loss due to dc bias dependence will become more pronounced. this will increase the tendency for phase shifting to occur, resulting in unstable operation. test thoroughly before using. for guidelines for the c l capacitance, check the XC6505 recommended capacitance characteristics (refer to operational expla nation, input/output capacitors). 5. torex places an importance on im proving our products and its reliability. however, by any possibility, we would request user fail- safe design and post-aging treatment on system or equipment. size unit manufacturer product number capacity [f] jis withstand temperature size voltage range lw [mm] eia [v] [] tdk c2012x7r1c225k 2.2 2012 0805 2.01.25 16 -55125 murata grm21br71c225k 2.2 2012 0805 2.01.25 16 -55125 taiyo yuden emk212b7225k 2.2 2012 0805 2.01.25 16 -55125
