This document describes the features and characteristics of the UC1524, UC2524, and UC3524 PWM modulators. They can be used to build regulating power supplies, inverters, or switching regulators, and can also be used as control elements for high-power output applications.
The UC1524 family consists of three fixed‑frequency pulse‑width‑modulation voltage regulator control circuits (UC1524, UC2524, UC3524). They integrate reference, error amplifier, oscillator, pulse‑steering flip‑flop, uncommitted output transistors and current‑limiting circuitry for use in switching regulators, inverters and power supplies. The devices support single‑ended or push‑pull output configurations and operate over a wide temperature range.
The datasheet includes detailed electrical characteristics, absolute maximum ratings, recommended operating conditions, packaging options, mechanical dimensions and a notice on product availability and warranty. Application circuits illustrate typical push‑pull, transformer‑coupled and single‑ended regulator topologies.
