SGM3204
Unregulated 200mA Charge Pump Voltage Inverter
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 output current range. 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 SGM3204 is available in a Green SOT-23-6 package. It operates over an ambient temperature range of -40 to +85.
