DESCRIPTION The IP1524 series of PWM switching regulator control circuits contains all the functions required to implement singleended or push-pull switching regulators. Included are voltage reference, error amplifer, oscillator, PWM parator, output drivers, current limiting and shutdown circuitry. Although functionally indentical to the SG1524 series, SEMELAB has incorporated several improvements to the IP1524 allowing tighter and more plete specification of electrical performance.
