Synchronous Buck PWM And Linear Controller

The APW7067N integrates synchronous buck PWM and linear controller, as well as monitoring and protection functions into a single package. The synchronous PWM controller drives dual N-Channel MOSFETs which provides one controlled power output with under-voltage and over- current protections. Linear controller drives an external N-Channel MOSFET with under-voltage protection. The APW7067N provides excellent regulation for output load variation. An internal 0.8V temperature-compensated reference voltage is designed to meet the requirement of low output voltage applications. The switching frequency is adjustable from 150kHz to 1000kHz. The APW7067N with excellent protection functions: POR, OCP and UVP. The Power-On-Reset (POR) circuit CAN monitor VCC12 supply voltage exceeds its threshold voltage while the controller is running, and a built-in digital soft-start provides both outputs with controlled rising voltage. The Over-Current Protection (OCP) monitors the output current by using the voltage drop across the lower MOSFET s R , comparing with DS(ON) internal V (0.25V), eliminating the need for a current OCP sensing resister. When the output current reaches the trip point, the controller will shutdown the IC directly, and latch the converter,s output. The Under-Voltage Protection (UVP) monitors the voltages of FB and FBL pins for short- Circuit Protection When the V or V is less than 50% FB FBL of V , the controller will shutdown the IC directly.
