MAX861 - Switched-Capacitor Voltage Converters

Download the MAX861 datasheet PDF (MAX860 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for switched-capacitor voltage converters.

Description

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.

19-0239; Rev 1; 11/96 MAX860/MAX861 50mA, Frequency-Selectable, Switched-Capacitor Voltage Converters _______________General Description 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.
