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 integrat-

ed circuit features a unique oscilla-

tor 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 protective fea-

tures consisting of input and refer-

ence undervoltage lockouts, each

with hysteresis, cycle-by-cycle cur-

rent limiting, and a latch for single

pulse metering of each output.

The CS5661 is pin compatible with

the MC34065L.
