MIC2141

Micropower Boost Converter

General Description

Features

The MIC2141 is a micropower boost switching regulator

•

Implements low-power boost, SEPIC, or flyback

that can operate from 3- or 4-cell nickel-metal-hydride

•

2.2V to 14V input voltage

batteries or a single Li-ion cell. This regulator employs a

•

330kHz switching frequency

constant 330kHz, fixed 18% duty-cycle, gated-oscillator

•

<2µA shutdown current

architecture.

•

70µA quiescent current

The MIC2141 can be used in applications where the

•

1.24V bandgap reference

output voltage must be dynamically adjusted. The device

features a control signal input which is used to

•

Typical output current 1mA to 10mA

proportionally adjust the output voltage. The control signal

•

SOT23-5 package

input has a gain of 6, allowing a 0.8V to 3.6V control signal

to vary a 4.8V to 22V output.

Applications

The MIC2141 requires only three external components to

operate and is available in a tiny 5-pin SOT-23 package for

•

LCD bias supply

space and power-sensitive portable applications. The

•

CCD digital camera supply

MIC2141 draws only 70µA of quiescent current and can

operate with an efficiency exceeding 85%.
