DESCRIPTION
TheL296andL296Parestepdownpowerswitching
regulatorsdelivering 4 A at a voltagevariable from
5.1V to 40 V.
Featuresof thedevicesincludesoftstart,remotein-
hibit, thermal protection, a reset output for micro-
processors and a PWM comparator input for syn-
chronizationin multichipconfigurations.

externalcomponents.
Efficient operation at switching frequencies up to
200 KHz allows a reductionin the size and cost of
external filter components. A voltage sense input
and SCR drive output are provided for optional
crowbar overvoltage protection with an external
SCR.
