SG1843Y Description

Short technical summary and product information.

The Microchip Technology SG1843Y is a DC DC Switching Controller IC with a buck topology, designed for step-down voltage conversion. It supports a wide supply voltage range from 7.6V to 30V, with a maximum rating of 30V. The device operates at switching frequencies up to 500kHz and has a maximum duty cycle of 95%.

 

This controller features a transistor driver output configuration and a single output phase. It includes under-voltage lockout protection with typical, minimum, and maximum thresholds. The operating temperature range is from -55°C to 125°C.

 

The SG1843Y is housed in an 8-CDIP package, measuring 0.300 inches (7.62mm). It is designed for through-hole mounting. The part has a maximum operating current of 17mA and a typical maximum output current of 200mA.

 

Compliance information indicates RoHS3 compliance and REACH unaffected status. The Moisture Sensitivity Level (MSL) is rated as 1.
