MCP1640/B/C/D
General Description
The MCP1640/B/C/D is a compact, high-efficiency,
fixed frequency, synchronous step-up DC-DC con-
verter. It provides an easy-to-use power supply solution
for applications powered by either one-cell, two-cell, or
three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or
Li-Polymer batteries.
Low-voltage technology allows the regulator to start up
without high inrush current or output voltage overshoot
from a low 0.65V input. High efficiency is accomplished
by integrating the low resistance N-Channel Boost
switch and synchronous P-Channel switch. All
compensation and protection circuitry are integrated to
minimize
applications, the MCP1640 operates and consumes
only 19 µA while operating at no load and provides a
true disconnect from input to output while shut down
(EN = GND). Additional device options are available
that operate in PWM only mode and connect input to
output bypass while shut down.
A “true” load disconnect mode provides input to output
isolation while disabled by removing the normal boost
regulator diode path from input to output. A bypass
mode option connects the input to the output using the
integrated low resistance P-Channel MOSFET, which
provides a low bias keep alive voltage for circuits
operating in Deep Sleep mode. Both options consume
less than 1 µA of input current.
Output voltage is set by a small external resistor
divider. Two package options, SOT23-6 and 2x3
DFN-8, are available.
