MAX860, MAX861 50mA、频率可选的开关电容电
max860, max861 50ma、频率可选的开关电容电压变换器
max860, max861概述
the max860/max861 charge-pump voltage converters invert input voltages ranging from +1.5v to +5.5v, or double input voltages ranging from +2.5v to +5.5v. because of their high switching frequencies, these devices use only two small, low-cost capacitors. their 50ma output makes switching regulators unnecessary, eliminating inductors and their associated cost, size, and emi. greater than 90% efficiency over most of the load-current range, combined with a typical operating current of only 200µa (max860), provides ideal performance for both battery-powered and board-level voltage-conversion applications.
a frequency-control (fc) pin provides three switching-frequencies to optimize capacitor size and quiescent current and to prevent interference with sensitive circuitry. each device has a unique set of three available frequencies. a shutdown (active-low shdn) pin reduces current consumption to less than 1µa. the max860/max861 are suitable for use in applications where the icl7660 and max660's switching frequencies are too low. the max860/max861 are available in 8-pin µmax and so packages.
