General Description
The APW7391 is a dual channel voltage mode, synchronous PWM controller which drives dual N-channel MOSFETs. The device integrates monitoring and protection functions into a single package, provides two controlled power output with under-voltage and overcurrent protections. The APW7391 provides excellent regulation for output load variation. The internal 1.0V temperature-compensated reference voltage provides high accuracy of 0.8% over line and load regulation. The PWM switching frequency is adjustable from 50KHz to 350KHz. The APW7391 has been equipped with excellent protection functions: POR, IMON, OCP, SCP, UVP, OVP OTP. The Power-On-Reset (POR) circuit can monitor the VCC input voltage to make sure the supply voltage is valid. The APW7391 adopts either the external power inductor’s DCR or an external accurate sense resistor to sense the output current. The output current information is reported at IMON pin whose output voltage is proportional to output current. During the PWM switching, the APW7391 has OCP and SCP protections. When the load current exceeds the OCP or SCP threshold, the APW7391 shuts off its PWM switcher to prevent catastrophic failure caused by abnormal load or short-circuit. The APW7391 senses its FB pin for output UVP and OVP protection, which is 50% and 120% of reference voltage respectively. When the UVP or OVP occurs, the APW7391 latches off the PWM switcher. APW7391 has over temperature protection. When the die temperature is above 150°C, the APW7391 ceases PWM operation and recover normal operation when the die temperature drops by 40°C. The APW7391 is available in SSOP-24 and SSOP-24P packages, which is compliant with RoHS.

General Description
The APW8833 integrates dual step-down, constant-ontime, synchronous PWM controllers (that drives dual Nchannel MOSFETs for each channel) and two low dropout 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 approximately 15V DC voltage. The APW8833 provides excellent transient response and accurate DC output voltage in either PFM or PWM Mode. In Pulse-Frequency Mode (PFM), the APW8833 provides very high efficiency over light to heavy loads with loadingmodulated 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. The APW8833 has individual enable controls for each PWM channels. Pulling both EN1/2 pin low shuts down the all of outputs. The LDO3 and LDO5 of APW8833 B/C/E/F are always on standby power. The APW8833 is available in a TQFN3x3-20 package.
