L296 Application Note

●The L296 is a high current step-down Power Switching Regulator delivering 4A at a voltage variable from 5.1 to 40V. It features of the devices include soft start, remote inhibit and thermal protection, a reset output for microprocessors and a PWM comparator input for synchronization in multichip configurations. An efficient operation at switching frequencies up to 200KHz allows a reduction in the size of external filter components. A voltage sense input and SCR drive output are provided for optional crowbar overvoltage protection with an external SCR.

● Very few external components

● Reset output

● Control circuit for crowbar SCR

● Input for remote inhibit and synchronous PWM

● Thermal shutdown
