DESCRIPTION

The L296andL296P are stepdownpower switching regulators delivering 4 A at a voltage variable from 5.1 V to 40 V.

Featuresof thedevices includesoft start,remotein hibit, thermal protection, a reset output for micro

processors and a PWM comparator input for synchronization in multichip configurations.
