The SGM6623 is a general-purpose miniature boost DC/DC switching regulator with high-efficiency for battery-backup and standby power systems. The acceptable input voltage range is between 0.8V and 12V that can be converted to a regulated 3.3V to 13V output voltage with efficiency as high as 90%. SGM6623 can be used as backup charger for systems with 1- to 4-cell batteries. It operates at a 600kHz nominal switching frequency, allowing the use of small and low-profile inductor for compact design. It also has several built-in protection features, such as cycle-by-cycle over- current limit, soft-start, thermal shutdown and open loop over-voltage protection.

The SGM6623 is available in a Green SOT-23-6 package.
