DESCRIPTION

The L296 andL296P are stepdownpower switching

regulators delivering 4 A at a voltage variable from

5.1 V to 40 V.

Featuresof the devices includesoft 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

® plasticpowerpackageandrequiresvery 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.
