Conv DC-DC Single Step Down 9V to 46V 15-Pin(15+Tab) MULTIWATT H

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 inhibit, thermal protection, a reset output for microprocessors and a PWM comparator input for synchronization in multichip configurations.The L296P incudes external programmable limiting current.The L296 and L296P are mounted in a 15-lead Multiwatt 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.
