UA78S40 Datasheet (Motorola) - UNIVERSAL SWITCHING REGULATOR SUBSYSTEM

UA78S40, UNIVERSAL SWITCHING REGULATOR SUBSYSTEM

Universal Switching Regulator Subsystem The µA78S40 is a switching regulator subsystem, consisting of a temperature compensated voltage reference, controlled duty cycle oscillator with an active current limit circuit, comparator, high current and high voltage output switch, capable of 1.5 A and 40 V, pinned out power diode and an uncommitted operational amplifier, which can be powered up or down independent of the IC supply.

The switching output can drive external

UA78S40 Features

* are wide

* supply voltage range, low standby current, high efficiency and low drift. The µA78S40 is available in commercial (0° to + 70°C), and automotive (
