UC2845 Datasheet (Unisonic Technologies) - HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

UC2845, HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

The UTC UC2844/2845 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 UC2844 and UC2845 are the maximum duty cycle ranges and under-voltage lockout thres
