PUCC3801 Product details

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 components.

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 components needed s Internal slope compensation. No external ramp components needed s Built-in over-voltage and under-voltage detection s High-speed over-current trip; 170 ns typical s Over-voltage clamp on supply voltage (VDD) s Internal divider regulates VDD to 12 V. No external divider needed s Leading edge bla.
