SG3525A Description

Short technical summary and product information.

The SG3525A is a Pulse Width Modulator (PWM) controller IC manufactured by ON Semiconductor. It is designed to offer improved performance and a reduced external parts count for controlling various types of switching power supplies. This controller operates within a wide voltage range of 8.0V to 35V and features a precise 5.1V, 1.0% trimmed reference voltage.

 

The SG3525A provides a 100 Hz to 400 kHz oscillator range and dual source/sink outputs capable of 400 mA peak current. It includes features such as adjustable deadtime control, input undervoltage lockout, and latching PWM to prevent multiple pulses. The IC is housed in a DIP-16 package, suitable for through-hole mounting.

 

This PWM controller is ideal for applications requiring efficient power management and stable output voltage control. Its integrated feedback circuitry allows for output voltage regulation by comparing a feedback signal with the internal reference voltage. The protection circuitry helps to shut down the PWM signal based on feedback current limits, enhancing system reliability.
