MAXIM INTEGRATED PRODUCTS  MAX1682EUK+T  芯片, 开关电容电压增被器

The is an ultra small switched capacitor voltage doubler in 5 pin SOT-23 package. This monolithic, CMOS capacitive charge pump voltage doubler doubles the voltage applied to its input and accepts input voltages ranging from 2V to 5.5V. The high voltage conversion efficiency of 99.9% and low operating current of 110µA make this device ideal for both battery powered and board level voltage doubler applications. Oscillator control circuitry and four power MOSFET switches are included on-chip. The MAX1682 operates at 12KHz. Typical application includes generating 6V supply to power an LCD display in hand held PDA.
