SG3524N Description

Short technical summary and product information.

The SG3524N is a versatile PWM controller IC from STMicroelectronics, incorporating essential functions for building regulating power supplies, inverters, and switching regulators. It is suitable for applications requiring fixed-frequency, pulse-width modulation (PWM) techniques, including transformer-coupled DC-to-DC converters and transformerless voltage doublers.

 

Key electrical specifications include an operating voltage range of 8V to 40V and a maximum duty cycle of 45%. The device operates at a frequency of 450kHz and features an enable control function. Its output configuration is positive, supporting both step-up and step-down functions with a topology suitable for flyback and push-pull applications.

 

Packaged in a 16-DIP (0.300", 7.62mm) through-hole configuration, the SG3524N is designed for a 0°C to 70°C operating temperature range. The standard package quantity is 25 units per tube. This controller integrates an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two uncommitted pass transistors, a high-gain comparator, and current-limiting and shutdown circuitry.
