General Description
The MCP16251/2 is a compact, high-efficiency, fixed
frequency, synchronous step-up DC-DC converter.
This family of devices 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-voltage 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 external components.
MCP16251/2 operates and consumes less than 14 µA
from battery after start-up, while operating at no load
(VOUT = 3.3V, VIN = 1.5V). The devices provide a true
disconnect from input to output (MCP16251) or an
input-to-output bypass (MCP16252), while in shutdown
(EN = GND). Both shutdown options consume less
than 0.6 µA from battery.
Output voltage is set by a small external resistor
divider. Two package options, SOT-23, 6-lead and
TDFN, 2 x 3 x 0.8 mm, 8-lead are available.
