SG1525AJ Description

Short technical summary and product information.

The SG1525AJ is a push-pull DC-DC switching controller from Microchip Technology, designed for step-up/step-down applications. It provides two transistor driver outputs with a single phase and positive output configuration. The controller supports synchronous rectification and clock synchronization for efficient power conversion. Control features include enable, frequency control, and soft start for flexible design integration.

 

The device operates over a wide supply voltage range of 8V to 35V and a switching frequency from 100Hz to 350kHz, with a maximum duty cycle of 49%. It is housed in a 16-pin CERDIP or CDIP package with through-hole mounting, suitable for industrial and military temperature ranges (-55°C to 125°C).

 

This controller is commonly used in isolated and non-isolated power supplies requiring push-pull topology, such as telecom, industrial, and aerospace systems. The wide operating temperature range allows operation in harsh environments, and the through-hole package ensures robust mechanical connection for high-reliability applications.
