SGM3204 Datasheet Text
SGM3204 Unregulated 200mA Charge Pump Voltage Inverter
GENERAL DESCRIPTION
The SGM3204 is a charge pump voltage inverter that is designed for operating over an input voltage range of 1.4V to 5.5V. The SGM3204 can provide up to 200mA output current. The typical conversion efficiency exceeds 80% over a wide range of output current. 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 plete charge pump inverter, making it ideal for numerous battery-powered and board level applications.
The SGM3204 is available in a Green SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
