Details

GENERAL DESCRIPTIONThe ADM8828/ADM8829 is a charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative –1.5 V to –5.5 V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge pump. Output currents up to 25 mA with greater than 99% efficiency are achievable.The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quies cent current to 20 nA.The ADM8828/ADM8829 is available in a 6-lead SOT-23 package.FEATURES Inverts Input Supply Voltage 99% Voltage Conversion Efficiency 25 mA Output Current Shutdown Function Requires Only Two Capacitors 1 mF Capacitors 18 V Output Resistance +1.5 V to +5.5 V Input Range 600 mA Quiescent Current 20 nA Shutdown Current (ADM8828)APPLICATIONS Handheld Instruments LCD Panels Cellular Phones PDAs Remote Data Acquisition Op Amp Power Supplies
