DESCRIPTION
The L296 and L296P are stepdown power switching
regulators delivering 4 A at a voltage variable from
5.1 V to 40 V.
Features of the devices include soft start, remote in-
hibit, thermal protection, a reset output for micro-
processors and a PWM comparator input for syn-
chronization in multichip configurations.
The L296P incudes external programmable limiting
current.

The L296 and L296P are mounted in a 15-lead Mul-
tiwatt plastic power package and requires very few
external components.
Efficient operation at switching frequencies up to
200 KHz allows a reduction in 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.
