SGM6623 4.4A, Miniature Boost Converter GENERAL DESCRIPTION FEATURES The SGM6623 is a general-purpose miniature boost ● 0.8V to 12V Input Voltage Range DC/DC switching regulator with high-efficiency for ● 3.3V to 13V Wide Output Voltage Range battery-backup and standby power systems. The ● 4.4A Current Limited Integrated Switch acceptable input voltage range of 0.8V to 12V can be ● Up to 90% Efficiency converted to a regulated 3.3V to 13V output voltage with ● 600kHz Nominal Fixed Switching Frequency with efficiency as high as 90%. SGM6623 can be used as Pulse Skipping at Light Loads backup charger for systems with 1- to 4-cell batteries. It ● Built-In Soft-Start Function operates at a 600kHz nominal switching frequency, ● Open Loop Over-Voltage Protection allowing the use of small and low-profile inductor for ● Enable Input Pin compact design. It also has several built-in protection ● 47μA Typical Quiescent Current (to VS Pin) features, such as cycle-by-cycle over-current limit, ● 0.4μA Typical Supply Current in Shutdown soft-start, thermal shutdown and open loop over-voltage ● Available in a Green SOT-23-6 Package protection. The SGM6623 is available in a Green SOT-23-6 package.
