Maxim Integrated (MAX871EUK+T) DC/DC Fixed Charge Pump Voltage Inverter,

DC/DC Fixed Charge Pump Voltage Inverter, 1.4 V to 5.5 V in, 25 mA out, 500 kHz, SOT-23-5 Product Overview The MAX871EUK+T is a switched capacitor voltage inverter in 5 pin SOT-23 package. This monolithic, CMOS charge pump inverter accepts input voltages ranging from +1.4V to +5.5V and operates at 500KHz. Its high efficiency and low operating current make this device ideal for both battery-powered and board-level voltage-conversion applications. Oscillator control circuitry and four power MOSFET switches are included on-chip. A typical MAX871 application is generating a -5V supply from a +5V logic supply to power analogue circuitry. It can deliver 25mA with a voltage drop of 500mV. This device is used in small LCD panels, cell phones, medical instruments, handy-terminals, PDAs and battery-operated equipment. Supply current is 2.7mA Operating temperature range from -40°C to 85°C Power efficiency is 75% Voltage conversion efficiency is 99% Invert input supply voltage Require only two capacitors Shutdown control Applications Power Management, Portable Devices Product Information Output Type: Fixed Input Voltage Min: 1.4V Input Voltage Max: 5.5V DC / DC Converter IC Case: SOT-23 No. of Pins: 5Pins Output Current: 25mA Topology: Inverting Operating Temperature Max: 85°C MSL: MSL 1 - Unlimited
