FP6711

High-Efficiency, 1-Cell and

2-Cell Boost Converter

Description

Features

The FP6711 is a high efficiency, fixed frequency

500KHz, current mode PWM boost DC/DC converter

which could operate from single/dual-cell NiCd,

NiMH or alkaline battery such as input voltage below

1V. The converter output voltage can be adjusted

from 1.8V to maximum 4V by an external resistor

divider. Besides the converter includes a 0.35Ω

N-channel MOSFET switch and 0.45Ω P-channel

synchronous rectifier. So no external Schottky

diode is required, and it could get better efficiency

near 94%.

● Synchronous Rectification: 94% Efficiency

● Very Low Start-up Voltage at 0.85V

● Automatically Switch to PFM Mode for Improving

Efficiency at Light Load

● Built-in True Shutdown: Isolation of Load from

Battery during Shutdown

● Internal Anti-Ringing Switch across Inductor

● Low Battery Warning Display

● Fixed Frequency Operation at 500kHz

● Very Low Shutdown Current at 1μA

● Small 10-Pin MSOP Package

● RoHS Compliant

The converter is based on a fixed frequency, current

mode, pulse-width-modulation PWM controller that

goes automatically into PFM mode at light load

which quiescent current is only 25μA in this mode

operation.

Applications

● Handheld Instrument

● Cordless Phone

● Wireless Handset

● GPS Receiver

● MP3

The converter features a special function that the

load is completely isolated from the battery during

shutdown.

Besides it also has auto-discharge

function which could discharge the output capacitor

immediately during shutdown.

When converter operates into discontinuous mode,

the internal anti-ringing switch will reduce

interference and radiated electromagnetic energy.

The FP6711 is available in a space-saving 10-lead

MSOP package for portable application.
