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 perfor-
mance for both battery-powered and board-level volt-
age-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 unique set of three available
frequencies. A shutdown (S H D N ) pin reduces current

______________Ordering Information
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.
