Simplified Application Circuit
The APW8823 integrates dual step-down, constant-on-
time, synchronous PWM controllers (that drives dual N-
channel MOSFETs for each channel) and two low drop-
out regulators as well as various protections into a chip.
The PWM controllers step down high voltage of a battery
to generate low-voltage for NB applications. The output
of PWM1 and PWM2 can be adjusted from 2V to 5.5V by
setting a resistive voltage-divider from VOUTx to GND.
The linear regulators provide 5V and 3.3V output for
standby power supply. The linear regulators provide up
to 100mA output current. When the PWMx output voltage
is higher than LDOx bypass threshold, the related LDOx
regulator is shut off and its output is connected to VOUTx
by internal switchover MOSFET. It can save power
dissipation. The charge pump circuit with 250kHz clock
driver uses VOUT1 as its power supply to generate ap-
proximately 15V DC voltage.
The APW8823 provides excellent transient response
and accurate DC output voltage in either PFM or PWM
Mode. In Pulse-Frequency Mode (PFM), the APW8823
provides very high efficiency over light to heavy loads
with loading-modulated switching frequencies. The
Forced-PWM Mode works nearly at constant frequency
for low-noise requirements. The unique ultrasonic
mode maintains the switching frequency above 25kHz,
which eliminates noise in audio application.
