AX3842P / AX3842S

High Performance Current Mode Pwm Controlers

8-Lead Plastic DIP-8

Package Code: P

Description

The AX3842 Series is high performance fixed frequency current mode controllers.

That is specifically designed for Off-Line and DC To DC converter applications

offering the designer a costeffective solution with minimal external components.

These integrated circuits feature a trimmed oscillator for precise duty cycle control.

A temperature compensated reference, high gain error amplifier, current sensing

compara-tor, and a high current totem pole output ideally suited for driving a

power MOSFET. Also included are protective features consisting of input and

reference undervoltage lockouts each with hysteresis, cycle-by-cycle current

limiting, programmable output deadtime, and a latch for single pulse metering.
