UC3844 - HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS
The UTC UC3844/3845 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 UC3844 and UC3845 are the under-voltage lockout thresholds.
