SG3525AN Description

Short technical summary and product information.

The SG3525AN from STMicroelectronics is a versatile pulse width modulator control circuit designed for efficient switching power supply implementation. It features a wide operating voltage range of 8V to 35V and an on-chip 5.1V reference trimmed to ±1%. The device supports adjustable deadtime control and includes built-in soft-start circuitry.

 

Key electrical characteristics include an oscillator frequency range from 100 Hz to 400 kHz and dual source/sink outputs capable of 400 mA peak current. The SG3525AN offers control features such as Enable and Soft Start, along with a latching PWM for preventing multiple pulses and pulse-by-pulse shutdown.

 

This controller is suitable for both step-down and step-up/step-down topologies, with a maximum duty cycle of 49%. It is packaged in a 16-DIP through-hole configuration, making it suitable for various PCB mounting requirements. The operating temperature range is 0°C to 70°C (TA).
