White LED Driver

with Synchronous Boost Converter

and PWM Brightness Control for up to 3 LEDs in Series

BD6071HFN

●General Description

●Key Specifications

BD6071HFN is boost DC/DC converter possible to

boost output voltage up to 14V (Max.) and drive the

white LEDs at constant. It is possible that turning on

white LED steadily by a series connection which has no

current variation, and by a fast transient response with

current mode. And, BD6071HFN is white LED driver IC

with synchronous rectification. With synchronous

rectification (no external schottky diode required) and

small package, they can save mount space.

 Operating power supply voltage range: 2.7V to 5.5V

 Switching frequency:

 Quiescent Current:

1MHz(Typ.)

0.1μA (Typ.)

 Operating temperature range:

-30°C to +85°C

●Package W(Typ.) x D(Typ.) x H(Max.)

●Features

 Boost DC/DC converter

 Adjustment of brightness by external PWM pulse

 Possible to driving 3 LEDs

 Soft start function

HSON8

2.90mm x 3.00mm x 0.60mm

 Synchronous rectification Boost DC/DC converter

 No external schottky diode required

 Output Open • Short protect

●Applications

This driver is applicable for various fields such as

mobile phones, portable game machines, Inter-phone

camera, audio player, portable DVD player, back light for

printer display etc… and support light of the camera for

the mobile phone, simple flash. And, these can use

power supply for OEL.
