SG1844Y-DESC Description

Short technical summary and product information.

The SG1844Y-DESC is an offline switching controller IC manufactured by Microchip Technology. It is designed for AC-DC converter and offline switch power supply applications.

 

The device operates from a supply voltage of 10V to 30V with a startup voltage of 16V. It features a switching frequency range from 100Hz to 500kHz and a fixed duty cycle of 48%. Fault protection is provided via current limiting, and the control feature includes frequency control for enhanced design flexibility.

 

Housed in an 8-CDIP (Ceramic Dual In-line Package) with through-hole mounting, the SG1844Y-DESC can operate over a wide temperature range of -55°C to +125°C, making it suitable for demanding environments. The package is supplied in tube packaging.
