LV49152V
Overview
Class-D Audio Power Amplifier
BTL 15W x 2ch
The LV49152V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49152V uses unique SANYO-developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can be used to implement high quality flat display panel (FDP) based systems.
Features
* BTL output, class D amplifier system * Unique SANYO-developed feedback technology achieves superb audio quality * High-efficiency class D amplifier * Soft muting function reduces impulse noise at power on/off * Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply voltage protection circuits * Built in Power limiter
Functions
* Power : 15W x 2ch output (VD = 15V, RL = 8, fin = 1kHz, AES17, THD + N = 10%) * Efficiency : 93% (VD = 15V, RL = 8, fin = 1kHz, PO = 15W) * THD + N : 0.08% (VD = 15V, RL = 8, fin = 1kHz, PO = 1W, Filter : AES17) * Noise : 90Vrms (Filter : A-weight) * Package SSOP44J (275mil)

Operation Mode Summary STBY mode (STBY = L and MUTE = L) Each bias becomes off state when the regulator in IC has been turned off. The most of circuits becomes off state. The supply current : 1A (typical). MUTE mode (STBY = H and MUTE = L) Each bias becomes on state when the regulator in IC has been turned on. When more than half of the circuits are active, the amplifier in the output stages become off. The supply current : 20mA (typical). Operation mode (STBY = H and MUTE = H) The LV49152V operates as D-class amplifier. The output signal is synchronized with the input signal. The supply current : 45mA (typical)

Power supply lowering protection circuit Since the instable operation in the low voltage is prevented by using this circuit, after the voltage of the PVD pin is monitored and the voltage below the Attack voltage (PVD = 8V typ.), AMP is turned off. Also, to prevent the instable operation when the voltage of the PVD pin is decreased by any cause during operations, the Attack voltage (PVD = 7V typ.) is set. The voltage of Attack and Recover has hysteresis (About 1V) to prevent ON/OFF continuous action of the power supply lowering protection circuit.

Over current protection circuit The over current protection circuit is a protection circuit * to protect the output DMOS from the over current and corresponds to any mode of the power supply, GND and a load short. The protection operation is performed when the current reaches the detection current value set out in IC and the output DMOS is compulsorily turned off for about 20sec. After compulsorily tuning off the output DMOS, when the Amplifier is automatically reset in usual operation and the over current flows continuously, the protection operation is performed again.

Thermal protection circuit The LV49152V includes a thermal protection circuit to prevent damage to or destruction of the IC should abnormal internal heat generation occur. This means that should the IC junction temperature (Tj) rise above about 175C due to inadequate heat dissipation or other reason, the thermal protection circuit will operate to stop IC operation should the temperature rise further. If the temperature is reduced by lowering the input level or other means, the thermal protection circuit will recover automatically (about 105C).

PLC The PLC (power level control) function is able to control the maximum index modulation by setting a value of external PLC resistance R1 voluntarily, and prevent a PWM signal from becoming the over modulation mode. In addition, this circuit can be use as output power limit circuit because the PLC function can set the maximum index modulation voluntarily, and variable from 2W to 15W with output power linearly in the state that made the power supply voltage and load resistance fixation. Because the PLC function can set the suitable rated output with the same power supply voltage/speaker regardless of screen size in flat screen televisions by this, set can plan the commonization of the board. Furthermore, The PLC function can reduce abnormal noise in the hard clip so that output wave pattern becomes the soft clip when it limited output power.

Cut-off frequency calculation method and the output LC filter setting
L
OUT+
C CL C OUTL RL
The cut off frequency fc of the output LC filter is calculated by the following formula. fc = 1 22LCL
Also, by setting the cut off frequency fc, the value of CL and L is calculated by using the following formula. 1 CL = 22 x RLfc L= 2 x RL 4 fc
In general, the value from 20% to 30% of CL is set to C. In case of fc = 30kHz
RL [] 4 6 8 16 L [H] 15 22 33 68 CL [F] 1 0.68 0.47 0.22 C [F] 0.22 0.15 0.1 0.047 Q 0.650 0.636 0.704 0.739
Above formula is common calculation method and is a measure of constant setting. In fact, it is necessary to set with each set that considers the speaker characteristics. In addition, please set the fixed number to become Q 1 in currents in the fc neighborhood increasing if Q value of the LC filter is big.
