DESCRIPTION

The UTC UC3846 control IC offers all necessary features for

accomplishment of fixed frequency, current mode control functions,

however it contains the least external parts. The performance of this

technique is superior to the others in better line regulation,

enhanced load response characteristics while designing a simpler

and easier control loop for design. It owns topological advantages of

inherent pulse-by-pulse current limiting, automatic symmetry

correction for push-pull converters, and the ability to parallel “power

modules" for equal current sharing.

SOP-16W

Protection loop includes soft start, built-in under-voltage lockout

and programmable current limit. The shutdown circuitry can

provide either a complete shutdown with automatic restart or the

supply off-latch.

In addition, many other features can also be available, including

fully latched operation, double pulse suppression, deadline adjust,

and a ±1% trimmed bandgap reference.

The UTC UC3846 features low outputs in the OFF state.
