SG3527A - REGULATING PULSE WIDTH MODULATOR

Download the SG3527A datasheet PDF. This datasheet also covers the SG3525A variant, as both devices belong to the same regulating pulse width modulator family and are provided as variant models within a single manufacturer datasheet.

Description

The SG1525A/1527A series of pulse width modulator integrated circuits are designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies.

Features

  • NOR logic, giving a LOW output for an OFF state. The SG1527A utilizes OR logic which results in a HIGH output level when OFF.

SG1525A/SG2525A/SG3525A SG1527A/SG2527A/SG3527A REGULATING PULSE WIDTH MODULATOR DESCRIPTION The SG1525A/1527A series of pulse width modulator integrated circuits are designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies. The on-chip +5.1 volt reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors. A Sync input to the oscillator allows multiple units to be slaved together, or a single unit to be synchronized to an external system clock. A single resistor between the CT pin and the Discharge pin provides a wide range of deadtime adjustment.
