SGM6623

4.4A, Miniature Boost Converter

GENERAL DESCRIPTION

FEATURES

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 of 0.8V to 12V 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 (TYP) 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.

● 0.8V to 12V Input Voltage Range

● 3.3V to 13V Wide Output Voltage Range

● 4.4A Current Limited Integrated Switch

● 47μA (TYP) Quiescent Current (to VS Pin)

● 0.4μA (TYP) Supply Current in Shutdown

● Up to 90% Efficiency

● 600kHz (TYP) Fixed Switching Frequency with

Pulse Skipping at Light Loads

● Enable Input Pin

● Built-in Soft-Start Function

● Open Loop Over-Voltage Protection

● Available in a Green SOT-23-6 Package

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