Overview
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.
A frequency-control (FC) pin provides three switching- frequencies to optimize capacitor size and quiescent current and to prevent interference with sensitive cir- cuitry.
Each device has a frequencies.
A shutdown (uS—nHi—qD—uNe–)speitno...
