NCP1411

Sync−Rect PFM Step−Up

DC−DC Converter with

Low−Battery Detector and

Ring−Killer

NCP1411 is a monolithic micropower high frequency Boost

(step−up) voltage switching converter IC specially designed for

battery operated hand−held electronic products up to 250 mA loading.

It integrates Synchronous Rectifier for improving efficiency as well as

eliminating the external Schottky Diode. High switching frequency

(up to 600 kHz) allows low profile inductor and output capacitor being

used. Low−Battery Detector, Logic−Controlled Shutdown and

Cycle−by−Cycle Current Limit provide value−added features for

various battery−operated applications. The innovative Ring−Killer

circuitry guarantees quiet operation in discontinuous conduction

mode. With all these functions ON, the device quiescent supply

current is only 9.0

mA typical. This device is available in the space

saving compact Micro8

t package.

Features

• Pb−Free Package is Available

• High Efficiency, up to 92%

• Very Low Device Quiescent Supply Current of 9.0 mA Typical

• Built−in Synchronous Rectifier (P−FET) Eliminates One External

Schottky Diode

• High Switching Frequency (up to 600 kHz) Allows use of Small Size

Inductor

• High Accuracy Reference Output, 1.19 V $ 0.6% @ 25°C, can

supply more than 2.5 mA when VOUT ≥ 3.3 V

• Ring−Killer for Quiet Operation in Discontinuous Conduction Mode

• 1.0 V Startup at No Load Guaranteed

• Output Voltage from 1.5 V to 5.5 V Adjustable

• Output Current up to 250 mA @ V

IN = 2.5 V, VOUT = 3.3 V

• Logic−Controlled Shutdown

• Open Drain Low−Battery Detector Output

• 1.0 A Cycle by Cycle Current Limit

• Low Profile and Minimum External Parts

• Compact Micro8 Package

Typical Applications

• Personal Digital Assistant (PDA)

• Handheld Digital Audio Product

• Camcorder and Digital Still Camera

• Handheld Instrument

• Conversion from One or Two NiMH or NiCd, or One Li−ion Cell

to 3.3 V/5.0 V
