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.
