5V To 12V Supply Voltage, 8-PIN, Synchronous Buck PWM Controller

The APW7120A is a fixed 300kHz frequency, voltage mode, and synchronous PWM Controller The device drives two low cost N-Channel MOSFETs and is de- signed to work with single 5~12V or two supply voltage(s), providing excellent regulation for load transients. The APW7120A integrates controls, monitoring and protection functions into a single 8-pin package to provide a low cost and perfect power solution. A power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong Logic controls. An internal 0.8V reference provides low output voltage down to 0.8V for further applications. An built-in digital soft-start with fixed soft-start interval prevents the output voltage from overshoot as well as limiting the input current. The controller,s over-current protection monitors the output current by using the voltage drop across the low-side MOSFET s R , eliminating the DS(ON) need of a current sensing resistor. Additional under voltage and over voltage protections monitor the voltage on FB pin for short-circuit and over-voltage protections. The over-current protection cycles the soft-start function until 4 over-current events are counted. By Anpec Electronics Corporation
