High Performance Current Mode Controllers
The UC3844, UC3845 series are high performance fixed frequency current mode controllers. They are specifically designed for Of.
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 dead times to be programmed for 50% to 70%.
