White LED Driver

With PWM Brightness Control

for up to 11 LEDs in Series

BD60A00NUX

BD60A60NUX

●General Description

●Key Specifications

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

This IC is boost DC/DC converter that can drive white

LED with constant current. More stabled white LED

lighting can be achieved by direct current connection

without electric tolerance and High-speed response by

current mode. Moreover, separating IC power supply

(2.7V to 5.5V) and coil power supply (2.3V to 20V)

makes it possible to widen input range, which will be

helpful to be applied to various kinds of applications.

Over voltage setting can be selected corresponding to

the number of LED lightings. BD60A00NUX is for max

11 lightings, BD60A60NUX is for max 6 lightings.

 LED maximum current:

●Package W(Typ.) x D(Typ.) x H(Max.)

●Features

 Boost DC/DC converter

 Drive LED 11 lightings

(VOUT=3.6V×11+0.7V=40.3V <VF MAX=3.7V>)

BD60A00NUX

 Brightness control by outside PWM signal (PWM

frequency =100Hz to 30kHz, 25kHz 1% dimming

application)

VSON008X2030

2.00mm x 3.00mm x 0.60mm
