BD9206EFV屬于集成電路（IC）的LED驅(qū)動器。由羅姆半導(dǎo)體集團制造生產(chǎn)的BD9206EFVLED 驅(qū)動器器件屬于 LED 驅(qū)動器電源管理集成電路 (PMIC) 系列，可通過標稱固定電壓的電源為負載（通常為發(fā)光二極管）提供電流，并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于，這類器件提供較低的反饋電壓（以提高系統(tǒng)能效），而且通?？蓪ζ骷ぷ鼽c進行外部控制，可在照明應(yīng)用中用于實現(xiàn)調(diào)光功能。

●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.
