DESCRIPTION
The IP1524 series of PWM switching regulator control circuits contains all the functions required to implement single-
ended or push-pull switching regulators. Included are voltage reference, error amplifer, oscillator, PWM comparator,
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 complete specification of electrical performance.
