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

- PFM Output Ripple: 150 mV typical

• Feedback Voltage: 1.23V

from

low-voltage input. High efficiency is

• Internal Synchronous Rectifier

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

(V_OUT= 3.3V, V_IN= 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.

• Internal Compensation

• Inrush Current Limiting and Internal Soft Start

(1.5 ms typical)

• Selectable, Logic Controlled, Shutdown States:

- True Load Disconnect Option (MCP16251)

- Input-to-Output Bypass Option (MCP16252)

•

Anti-Ringing Control

• Overtemperature Protection

• Available Packages:

- SOT-23, 6-Lead

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.

- TDFN, 2 x 3 x 0.8 mm, 8-Lead
