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...
