High performance current mode pwm controller.
UC3844B, UC3845B,
UC2844B, UC2845B
High Performance Current Mode Controllers
The UC3844B, UC3845B series are high performance fixed frequency current .
* 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 7
