UC3844 HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

UC3844 Description

UNISONIC TECHNOLOGIES CO., LTD UC3844/45 HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS LINEAR INTEGRATED CIRCUIT * .
The UTC UC3844/3845 are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter appli.

UC3844 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

UC3844 Applications

* with minimal external parts count. The differences between UC3844 and UC3845 are the under-voltage lockout thresholds. The UC3844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3845 has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage applicati
