Description:

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

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

Applications

* with minimal external parts count. The differences between UC1842B-D and UC1843B-D are the under-voltage lockout thresholds. The UC1842B-D ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC1843B-D has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower volta
