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 m...
