This device combines a current mode PWM controller with a high voltage power SenseFET in a single package. The PWM controller features an integrated oscillator to be synchronized with the external sync signal, under voltage lockout, optimized gate driver and temperature-compensated precise current sources for the loop compensation. This device also includes various fault protection circuits such as over voltage protection, over load protection, abnormal over current protection and over temperature protection. Compared with discrete MOSFET and PWM controller solutions, FPS can reduce total cost, component count, size and weight while simultaneously increasing efficiency, productivity and system reliability. This device is well suited for cost effective CRT-monitor power supplies. Notes: 1. Maximum practical continuous power in an open frame design at 50 °C ambient. 2. 230 VAC or 100/115 VAC with doubler. 3. The maximum output power can be limited by the junction temperature Typical Circuit Figure 1.
