CS5661
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.
V
OUT2
output is switchable via the
ENABLE

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.
