UC3842A CURRENT MODE PWM CONTROLLER

UC3842A Description

UNISONIC TECHNOLOGIES CO., LTD UC3842A/3843A LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS * .
The UTC UC3842A/3843A are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter app.

UC3842A Features

* Operation output switching frequency up to 500 kHz
* Automatic feed forward compensation
* Latching PWM for cycle-by-cycle current limiting
* High current totem pole output
* Internally trimmed reference with under voltage lockout
* UVLO with hysteresis
* Low startup an

UC3842A Applications

* with minimal external parts count. The differences between UC3842A and UC3843A are the under-voltage lockout thresholds. The UC3842A ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3843A has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage appli
