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).
This technical note introduces the BD9206EFV LED driver IC, a constant‑current driver capable of powering up to 36 white LEDs (6 × 6 configuration). It highlights a wide input voltage range of 8 V to 30 V, low standby current, PWM dimming, and a high‑heat‑radiation HTSSOP‑B20 package.
The document provides electrical characteristics, block diagrams, terminal descriptions, timing charts, and recommended circuit examples. Protection functions such as UVLO and thermal shutdown (TSD) are explained, along with ordering information and legal notices.
