Description:

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

Note:

This datasheet PDF includes multiple part numbers: UC2844, UC2845.
Please refer to the document for exact specifications by model.

Features

* Operation output switching frequency up to 500 kHz
* Output deadtime adjustable from 50% to 70%
* Automatic feed forward compensation
* Latching PWM for cycle-by-cycle current limiting
* High current totem pole output
* Internally trimmed reference with under voltage locko

Applications

* with minimal external parts count. The differences between UC2844 and UC2845 are the maximum duty cycle ranges and under-voltage lockout thresholds. The UC2844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC2845 has UVLO thresholds of 8.5V(ON) and 7.6V(OF
