SGM3206

Unregulated 60mA

Charge Pump Voltage Inverter

GENERAL DESCRIPTION

FEATURES

The SGM3206 is a charge pump voltage inverter that is

designed for operating over an input voltage range of

1.4V to 5.5V. The SGM3206 can provide up to 60mA

output current. The typical conversion efficiency

exceeds 85% over a wide range of output current. The

fixed switching frequency is 47kHz. 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.

● Input Voltage Range: 1.4V to 5.5V

● Inverts Input Supply Voltage

● Output Current: 60mA

● Quiescent Current: 115μA (TYP)

● Integrated Active Schottky Diode for Startup into

Load

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green SOT-23-5 Package

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.
