GENERAL DESCRIPTION
The internal 0.6V temperature-compensated reference voltage is designed to meet the requirement of low output voltage applications. The device includes a 200kHz free-running triangle-wave oscillator that is adjustable from 50kHz to 1000kHz. The APW7073 has been equipped with excellent protection functions: POR, OCP, and UVP. The Power-On-Reset (POR) circuit can monitor the VCC, EN, and OCSET voltage to make sure the supply voltage exceeds their threshold voltage while the controller is running. The Over-Current Protection (OCP) monitors the output current by using the voltage drop across the upper MOSFET’s R .
