SG2524 SG3524
REGULATING PULSE WIDTH MODULATORS
COMPLETE PWM POWER CONTROL CIRCUITRY UNCOMMITTED OUTPUTS FOR SINGLEENDED OR PUSH PULL APPLICATIONS LOW STANDBY CURRENT 8mA TYPICAL OPERATION UP TO 300KHz 1% MAXIMUM TEMPERATURE VARIATION OF REFERENCE VOLTAGE
DIP16 SO16
DESCRIPTION The SG2524, and SG3524 incorporate on a single monolithic chip all the function required for the construction of regulating power suppies inverters or switching
regulators. They can also be used as the control element for high power-output applications. The SG3524 family was designed for switching
regulators of either polarity, transformer-coupled dc-to-dc converters, transformerless voltage doublers and polarity converter applications employing fixed-frequency, pulse-width modulation techniques. The dual alternating outputs allows either single-ended or push-pull appliBLOCK DIAGRAM

cations. Each device includes an on-ship reference, error amplifier, programmable oscillator, pulse-steering flip flop, two uncommitted output
transistors, a high-gain comparator, and currentlimiting and shut-down circuitry.
