LED Drivers for LCD Backlights

White Backlight LED Drivers

for Small to Medium LCD Panels

(Switching Regulator Type)

BD60A00NUX, BD60A60NUX

No.11040EAT42

●Description

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~5.5V) and coil power supply (2.3V~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.

●Features

1) Boost DC/DC converter

2) Drive LED 11 lightings (VOUT=3.6V×11+0.7V=40.3V <Vf MAX=3.7V>) BD60A00NUX

3) Brightness control by outside PWM signal (PWM frequency =100Hz~30kHz, 25kHz 1% dimming application)

4) Brightness control by DC input

5) Soft start function (1ms typ.)

6) Over voltage protection 42V typ. ( BD60A00NUX), 28Vtyp.( BD60A60NUX)

7) SBD open protection and output short protection

8) Over current protection

9) LED terminal over voltage protection

10) UVLO

11) VSON008x2030 package (2.0mm × 3.0mm × 0.6mm MAX)

●Applications

Digital video cameras, digital single-lens reflexes, digital still cameras, digital photo frames, personal navigations (PND),

mobile phones, smart phones, MID, PDA, hand-held computers, MP3 players, GPS, digital media players, etc.
