78S40, UNIVERSAL SWITCHING REGULATOR SUBSYSTEM

Order this document µA78S40/D µA78S40 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.

78S40 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 (

* 40° to + 85°C) temperature ranges. Some of the applications include use in step

* up, step

* down, and inverting regu
