PUCC3801 Datasheet | NXP Semiconductors

Current-mode PWM controller Rev. 01 - 10 September 2001 Product data 1. General description The PUCC3801 is a current-mode Pulse Width Modulated (PWM) controller containing all the control and protection functions necessary to implement an off-line, flyback or forward converter with a minimum number of external ponents. 2. Features s Very low start-up supply current; 50 µA typical s Low operating supply current; 1.2 mA typical s Accurate, internally-trimmed, fixed frequency oscillator (100 kHz). No external timing ponents needed s Internal slope pensation. No external ramp ponents needed s Built-in over-voltage and under-voltage detection s High-speed over-current...
