资 源 简 介
The SG2524 and SG3524 incorporate all thefuncTIons required in the construcTIon of aregulaTIng power supply, inverter, or switchingregulator on a single chip. They also can be usedas the control element for high-power-outputapplicaTIons. The SG2524 and SG3524 weredesigned for switching regulators of either polarity, transformer-coupled dc-to-dc converters, transformerlessvoltage 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 deviceincludes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommittedpass transistors, a high-gain comparator, and current-limiting and shutdown circuitry.
