UC1843B-D, UC1842B-D Datasheet - UTC

UC1843B-D HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

The UTC UC1842B-D/1843B-D are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count. The differences between UC1842B-D and UC1843B-D are the under-voltage lockout thresholds. The UC1842B.

UC1843B-D 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
