MP3221

2.7A, 1.2MHz, High-Efficiency

Step-Up Converter

With Input Disconnect

DESCRIPTION

FEATURES

The MP3221 is a 1.2MHz frequency, 6-pin

TSOT23 current mode step up converter

intended for small, low power applications. The

device can step up three-cell alkaline, NiCd,

and NiMH batteries, or a single-cell Li-on

battery up to 6V. It is capable of delivering 1A

output current at 5V with a supply voltage of 3V.



Integrated 88mΩ Power MOSFET

270µA Quiescent Current

2.5V to 6V Input Voltage

3V to 6V Output Voltage

1.2MHz Fixed Switching Frequency

Internal 2.7A Switch Current Limit

Integrated Input Disconnect Driver

Internal Soft Start and Compensation

True Output Disconnect from Input

Under Voltage Lockout

Short-Circuit Protection

Over-Temperature Protection

Available in a 6-Pin TSOT23-6 Package

The MP3221 provides the internal soft start and

compensation to minimize the external

component count and help producing a

compact solution. It integrates a FAULT driver

for external PMOS to disconnect the output

from input when the part shuts down or in

output short circuit condition. This disconnect

feature allows the output to be completely

discharged, thus allowing the part to draw less

than 1µA off current in shutdown mode.

APPLICATIONS



Single-Cell Lion Battery or Three-Cell

Alkaline, NiCd, or NiMH Battery Based

Products

Portable Media Players

Wireless Peripherals

The MP3221 is available in a small 6•pin

TSOT23 package.



Tablets and Smart Phones
