The CS3865C is a high performance, fixed frequency, dual current mode controller. It is used in Off-Line and DC to DC converter applications and require a minimum number of external components. This integrated circuit features a unique oscillator for precise duty cycle limit and frequency control, a temperature compensated reference, two high gain error amplifiers, two current sensing comparators, and two high current totem pole outputs ideally suited for driving power MOSFETs. One of the outputs VOUT2 is switchable via the ENABLE 2 pin.
Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting, and a latch for single pulse metering of each output.
The CS3865C has a 14V start voltage and is pin compatible with the MC34065H.
