SG3527A PULSE WIDTH MODULATOR

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 .

SG3527A 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

* 5.1 V ± 1.0% Trimmed Reference

* 100 Hz to 400 kHz Oscillator Range

* Separate Oscillator Sync Pin
