UC3843B, UC3842B CONTROLLERS

UC3843B Description

UNISONIC TECHNOLOGIES CO., LTD UC3842B/3843B LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE CONTROLLERS * .
The UTC UC3842B/3843B are specifically designed for off-line and dc-to-dc converter applications offering the designer a cost-effective solution with.

UC3843B Features

* Trimmed oscillator for precise frequency control
* Oscillator frequency guaranteed at 250kHz
* Current mode operation to 500kHz
* Automatic feed forward compensation
* Latching PWM for cycle-by-cycle current limiting
* Internally trimmed reference with undervoltage lockout

UC3843B Applications

* offering the designer a cost-effective solution with minimal external components. The UC3842B has UVLO thresholds 16V (on) and 10V(off), ideally suited for off-line converters. The UC3843B is tailored for lower voltage applications having UVLO thresholds of 8.4V(on) and 7.6V(off).
