SG3526 Datasheet Regulating Pulse Width Modulator

Manufacturer: Microsemi (now Microchip Technology)

Overview: SG1526/SG2526/SG3526 REGULATING PULSE WIDTH MODULATOR.

General Description

The SG1526 is a high-performance monolithic pulse width modulator circuit designed for fixed-frequency switching regulators and other power control applications.

Included in an 18-pin dual-in-line package are a temperature pensated voltage reference, sawtooth oscillator, error amplifier, pulse width modulator, pulse metering and steering logic, and two low impedance power drivers.

Also included are protective

Key Features

  • such as soft-start and undervoltage lockout, digital current limiting, double pulse inhibit, a data latch for single pulse metering, adjustable deadtime, and provision for symmetry correction inputs. For ease of interface, all digital control ports are TTL and B-series CMOS compatible. Active LOW logic design allows wired-OR connections for maximum flexibility. This versatile device can be used to implement single-ended or push-pull switching regulators of either polarity, both transformerless a.
