BD9206EFV
No.09040EAT03
●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).
●Features
1) A wide input voltage range（8V～30V）
2) Capable of driving a maximum of 36 white LEDs of 6 series×6 parallel
3) Value of constant current is set by the VSET terminal
4) Due to the STBY terminal, the consumption current at the time of standby is low
5) PWM dimming is possible due to the clock input to the EN terminal
6) Built-in 5V regulator
7) High-heat-radiation package of HTSSOP-B20 6.4×6.5×0.85mm
●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.
●Absolute maximum ratings（Ta＝25℃）
