Datasheet
LED Driver Series for LCD Backlight
Simple Structure Constant Current
Backlight Driver for LCD panels
(Non-step type)
BD9206EFV
● General Description
BD9206EFV is an IC with a built-in 6ch high-accuracy
(absolute accuracy: ± 4%) constant-current driver.
Capable of lighting a maximum of 36 white LEDs with
6 rows×6 lines.
Due to the wide input voltage range (8V~30V), it can
be widely used from a backlights of Note PC and PDA
etc. to LED light sources of Scanner and PPC etc.
Moreover, it restrain the generation of heat at the time
of large current drive because of adoption of
high-heat-radiation package(HTSSOP-B20).
● Key Specifications
● Features
■ A wide input voltage range （ 8V to 30V ）
■ Capable of driving a maximum of 36 white LEDs
of 6 series×6 parallel
■ Value of constant current is set by the VSET
terminal
■ Due to the STBY terminal, the consumption
current at the time of standby is low
■ PWM dimming is possible due to the clock input to
the EN terminal
■ Built-in 5V regulator
Operating power supply voltage range: 8V to 30V
Operating Current: 2.5mA (typ.)
Maximun LED Constant current: 30mA (max.)
Operating temperature range: -40 ℃ to +85 ℃
● Applications
For use in LED light source of PPC and Scanner etc.,
LED lighting fixture, and LCD backlight lights of
monitor and note PC etc.
