Quality Control: Learn More
The Microchip Technology SG2845DM is a high-performance flyback DC-DC controller IC designed for positive output, isolation-capable applications. This device integrates a voltage mode controller with a current mode PWM architecture, suitable for step-up and step-down power conversion. It features a wide operating voltage range from 7.6V to 30V and supports switching frequencies from 1Hz up to 500kHz. The SG2845DM's duty cycle is limited to a maximum of 48%, and it includes a synchronous rectifier for enhanced efficiency. Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount component, this controller is utilized in power supplies for consumer electronics, industrial automation, and telecommunications equipment.
