Overview
LM78S40 Universal Switching Regulator Subsystem April 1998 LM78S40 Universal Switching Regulator Subsystem General Description The LM78S40 is a monolithic regulator subsystem consisting of all the active building blocks necessary for switching regulator systems.
The device consists of a temperature compensated voltage reference, a duty-cycle controllable oscillator with an active current limit circuit, an error amplifier, high current, high voltage output switch, a power diode and an uncommitted operational amplifier.
The device can drive external NPN or PNP transistors when currents in excess of 1.
5A or voltages in excess of 40V are required.
The device can be used for step-down, step-up ...
