1 / 24 page SG2524, SG3524 REGULATING PULSEWIDTH MODULATORS SLVS077D – APRIL 1977 – REVISED FEBRUARY 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Complete Pulse-Width Modulation (PWM) Power-Control Circuitry D Uncommitted Outputs for Single-Ended or Push-Pull Applications D Low Standby Current...8 mA Typ D Interchangeable With Industry Standard 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.
