Maxim Integrated MAX828
The MAX828 operates at 12kHz, and the MAX829 operates at 35kHz. The MAX828/MAX829 combine low quiescent current and high efficiency. Their high efficiency (greater than 90% over most of the load-current range) and low operating current (60µA for the MAX828) make these devices ideal for both battery-powered and boardlevel voltage-conversion applications.- Min Voltage : 1.25V

DESCRIPTION
The ultra-small MAX828/MAX829 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.5V to +5.5V. Oscillator control circuitry and four power MOSFET switches are included on-chip.APPLICATIONS
include generating a -5V supply from a +5V logic supply to power analog circuitry. Both parts come in a 5-pin SOT23-5 package and can deliver 25mA with a voltage drop of 500mV. For applications requiring more power, the MAX860 delivers up to 50mA with a voltage drop of 600mV, in a space-saving µMAX package. ____________________________Features o 5-Pin SOT23-5 Package o 95% Voltage Conversion Efficiency o Inverts Input Supply Voltage o 60µA Quiescent Current (MAX828) o +1.5V to +5.5V Input Voltage Range o Requires Only Two Capacitors o 25mA Output Current MAX828/MAX829 ______________Ordering Information PART MAX828C/D MAX828EUK MAX829C/D MAX829EUK TEMP.
