GENERAL DEscriptION
The SGM3207 is a charge pump voltage inverter that is designed for operating over an input voltage range of 1.4V to 5.5V. The SGM3207 can provide up to 60mA output current. The typical conversion efficiency exceeds 85% over a wide output current range. The fixed switching frequency is 19kHz. The wide supply voltage is well suited for various applications powered by a 1-cell Li-Ion battery, as well as 2-cell or 3-cell NiCd, NiMH or Alkaline batteries.
The shutdown current is less than 1μA. This device requires one flying capacitor and two small bypass capacitors for a complete charge pump inverter, making it ideal for numerous battery-powered and board level applications.
The SGM3207 is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40℃ to +85℃.
