Dual Channel Synchronous Buck PWM Controller
Features
- Discontinuous Conduction Mode in Light Load to Increase Efficiency (VEN=2V)
- Sence External RSENSE (option 2)
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.

9V to 18V eFuse With Fast Overvoltage Response Time
Features
General Description
APL3693 is a high-performance power protecting and management solution electronic fuse in DFN 3x3 package type. Have wide operation voltage range from 9V to 18V and integrate enable function, internal MOSFET have very low on resistance 40mΩ. The output voltage slew rate can be set with a single capacitor (CdV/dt) and also can floating the dV/dt pin and the output slew rate by internal setting. And output current limit is fixed with a single resistor (RLIMIT). Output voltage have a clamping voltage 13.5V with quickly response time 0.5μs when VCC voltage rising to over voltage clamp threshold 13.7V. APL3693 operation temperature from -40oC to 125oC. And turn off the output when temperature exceeds 150oC.

General Description
The APW7720 is a Power Management IC (PMIC) designed to provide complete power management solution for Surveillance Cam, IP Cam and Video Conference-Call applications. It integrates a PWM power stage and well-designed control circuitry to minimize the need for external components, thereby simplifying layout in constrained PCB areas. This device features 7 adjustable output voltage buck converters, 6 adjustable output voltage low-noise LDOs, and 2 sets of built-in logic control signal outputs selectable at 1.8V or 3.3V, all of which can be configured via I2C. The APW7720 features protection functions against over current, output over/under voltage, VSYS over voltage and over temperature to prevent catastrophic failure. Fault events also cause a state change on the PGOOD and /INT output pins, which is helpful for interrupt control or debugging. Additionally, it integrates two Under-Voltage Lockout (UVLO) features to monitor the voltages of VSYS and VINLDO1, thereby preventing improper operation during power-up and power-down. An I2C interface is provided in this device for the system designer to customize settings or presets using Multi-Time Programmable (MTP) features, including power-up/
down sequence, output voltage, ramp-up/down time, power-good delay time, watchdog timer, PWM switching frequency, forced PWM mode or automatic PFM/PWM mode, output discharge mode or ramp-down mode, and latch off mode or auto-reboot mode. These customizable MTP settings give system designers the flexibility to optimize performance for various use cases, ensuring efficient and reliable operation. The APW7720 is halogen and lead free device, compliant with RoHS, available in TQFN6x6-52B package.
