MP3414

1.8A,1MHz, Synchronous, Step-up

Converter with Output Disconnect

The Future of Analog IC Technology

FEATURES

DESCRIPTION

The MP3414 is a high-efficiency, synchronous,

current–mode, step-up converter with output

disconnect.



Up to 96% Efficiency

0.8V Low Voltage Start-Up

0.6V-to-4V Input Range

1.8V-to-4V Output Range

Internal Synchronous Rectifier

1MHz Fixed-Frequency Switching

35μA Quiescent Current

1μA Shutdown Current

Current-Mode Control with Internal

Compensation

The MP3414 can start up from an input voltage

as low as 0.8V to provide inrush current limiting,

and output short-circuit protection. The

integrated, P-channel, synchronous rectifier

improves efficiency and eliminates the need for

an external Schottky diode. The PMOS

disconnects the output from the input when the

part shuts down. This output disconnect feature

allows the output to be completely discharged,

thus allowing the part to draw a 1μA supply

current in shutdown mode.



True Output Disconnect from Input

V_IN>V_OUTDown Mode Operation

High Efficiency under Light-Load Conditions

Very Small External Components

Inrush Current Limiting and Internal Soft-

Start

The 1MHz switching frequency allows for

smaller external components, while the internal

compensation and the soft-start minimize the

external component count: these feature help to

produce a compact solution for a wide current

load range.



Over-Voltage Protection

Short-Circuit Protection

TSOT23-8 Package

APPLICATIONS



Battery-Powered Products

Personal Medical Devices

Portable Media Players

Wireless Peripherals

Handheld Computers and Smartphones

The MP3414 features an integrated power

MOSFET that supports up to a 4V output and a

typical 1.8A peak switching current.

The MP3414 is available in a small 8-pin

TSOT23 package.

All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For
