Overview
XR-495 Pulse-Width Modulating Regulator GENERAL DESCRIPTION FUNCTIONAL BLOCK DIAGRAM The XR-495 is a monolithic pulse width modulating regulator designed to contain all blocks necessary for a switching regulator.
Included in the 16 pin dual in-line packages is a voltage reference, oscillator, control logic, error amplifiers, and dual uncommitted outputs.
This device can be used for switching regulators of either polarity, polarity converters, transformer coupled DC to DC converters, transformerless voltage doublers, and many other power control applications.
A 39V zener diode allows operation with supply voltages exceeding 40V.
The XR-495M is fully specified for operation over the full military temperature range from - 55°C to + 125°C, while the XR-495CN and XR-495CP are designed for commercial applications over O°C to + 70 o e.
