Part Number	UC3844B
Manufacturer	American First Semiconductor
Title	Controllers
Description	UC3842B/3B/4B/5B,UC2842B/3B Package outline The UC3842B/3B/4B/5B, series are high performance fixed frequency current mode controllers. They are specifically designed for Off–Line and dc–to–dc converter applications offering the designer a cost–effective solution with minimal external components. .
Features	consisting of input and reference undervoltage lockouts each with hysteresis, cycle –by –cycle current limiting, programmable output deadtime, and a latch for single pulse metering. These devices are available in an 8 –pin dual –in –line and surface mount (SO –8) plastic package as well as the 14 –pin plastic surface mount (SO –14). The SO –14 package has separate power and ground pins for the totem pole o.

Title	HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER
Description	UC3844B, UC3845B, UC2844B, UC2845B High Performance Current Mode Controllers The UC3844B, UC3845B series are high performance fixed frequency current mode controllers. They are specifically designed for Off−Line and dc−dc converter applications offering the designer a cost−effective solution with mi.
Features	consisting of input and reference undervoltage lockouts each with hysteresis, cycle−by−cycle current limiting, a latch for single pulse metering, and a flip−flop which blanks the output off every other oscillator cycle, allowing output deadtimes to be programmed from 50% to 70%. These devices are available in an 8−pin dual−in−line and surface mount (SOIC−8) plastic package as well as the 14.
