Synchronous Buck PWM Controller

The APW7065A uses fixed 300kHz switching frequency, voltage mode, synchronous PWM Controller which drives dual N-Channel MOSFETs The device integrates the control, monitoring and protection functions into a single package, provides one controlled power output with under-voltage and over-current protections. The APW7065A provides excellent regulation for out- put load variation. The internal 0.8V temperature-com- pensated reference voltage is designed to meet the re- quirement of low output voltage applications. An built-in digital soft-start with fixed soft-start interval prevents the output voltage from overshoot as well as limiting the in- put current. The APW7065A with excellent protection functions: POR, OCP and UVP. The Power-On-Reset (POR) cir- cuit CAN monitor VCC supply voltage exceeds its thresh- old voltage while the controller is running, and a built-in digital soft-start provides output with controlled voltage rise. The Over-Current Protection (OCP) monitors the output current by using the voltage drop across the lower MOSFET s R , comparing with internal V (0.29V), DS(ON) OCP when the output current reaches the trip point, the IC shuts off the converter and initiates a new soft-start process. After two over-current events are counted, the device turns off both high-side and low-side MOSFETs and the converter's output is latched to be floating. It requires a POR of VCC to restart. The Under- Voltage Protection (UVP) monitors the voltage of FB pin for short-circuit protection, when the V is less than FB 50% of V (0.4V), the controller will shutdown the IC REF directly.
