The SG3525A is a high-performance pulse width modulator (PWM) controller IC designed for switch-mode power supply (SMPS) and DC-DC converter applications. It integrates all the necessary functions for regulating the output voltage and current, including an oscillator, error amplifier, PWM comparator, and output drivers. With an adjustable output and wide input voltage range up to 35V, the SG3525A ensures flexible and stable operation in power control circuits. The IC offers features like soft start, shutdown, and undervoltage lockout, making it ideal for designing regulated power supplies and inverters. Packaged in a standard DIP-16 through-hole format, it is well-suited for prototyping and repair applications.
