Description

The CS5661 is a high performance, fixed frequency, dual current mode controller specifically designed for Off-Line and DC to DC converter applications. It offers the designer a cost effective solution with minimal 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. VOUT2 output is switchable via the ENABLE2 pin.

Also included are CS5661 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 CS5661 is pin compatible with the MC34065L.
