Overview

Order this document by SG3525A/D Pulse Width Modulator Control Circuits The SG3525A, SG3527A pulse width modulator control circuits offer improved performance and lower external parts count when implemented for controlling all types of switching power supplies.

The on–chip +5.1 V reference is trimmed to ±1% and the error amplifier has an input common–mode voltage range that includes the reference voltage, thus eliminating the need for external divider resistors.

A sync input to the oscillator enables multiple units to be slaved or a single unit to be synchronized to an external system clock.

Key Features

NOR logic resulting in a low output for an off.
state while the SG3527A utilized OR logic which gives a high output when off.
8.0 V to 35 V Operation SG3525A SG3527A PULSE WIDTH.
