SG3525AN ST PWM Controller | 16-DIP (0.300", 7.62mm) | 8-35V, 100-500kHz

Product Overview

The SG3525AN from STMicroelectronics is a monolithic integrated circuit designed for pulse width modulation (PWM) control systems. It offers improved performance and reduced external parts count compared to earlier PWM controllers. The device features an on-chip 5.1V reference, error amplifier, programmable oscillator, under-voltage lockout (UVLO), soft-start, and shutdown functions. It is housed in a 16-pin DIP package (0.300", 7.62mm pitch) suitable for through-hole mounting.
