Key Features

Very low start-up supply current; 50 A typical

Low operating supply current; 1.2 mA typical

Accurate, internally-trimmed, fixed frequency oscillator (100 kHz). No external timing components needed

Internal slope compensation. No external ramp components needed

Built-in over-voltage and under-voltage detection

High-speed over-current trip; 170 ns typical

Over-voltage clamp on supply voltage (VDD)

Internal divider regulates VDD to 12 V. No external divider needed

Leading edge blanking of the current sense signal

Control frequency modulated over a narrow band to reduce Electromagnetic Interference (EMI)

High output drive capability; 150 ns typical rise and fall time into 2 nF load

Wide bandwidth (10 MHz) error amplifier with external compensation pin and simple interface to optocoupler

Accurate internal bandgap reference.

Application

Off-line switched mode power supplies

Laptop computer mains adaptors

Printer power supplies.
