SG2524 and SG3524
description/ordering information
The SG2524 and SG3524 incorporate all the
functions required in the construction of a
regulating power supply, inverter, or switching
regulator on a single chip. They also can be used
as the control element for high-power-output
applications. The SG2524 and SG3524 were
designed for switching regulators of either polarity, transformer-coupled dc-to-dc converters, transformerless
voltage doublers, and polarity-converter applications employing fixed-frequency, pulse-width modulation
(PWM) techniques. The complementary output allows either single-ended or push-pull application. Each device
includes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommitted
pass transistors, a high-gain comparator, and current-limiting and shutdown circuitry.
