BD6088GUL is a intelligent LED driver from ROHM company, it is suitable for mobile phone. It has 6 LED drivers and 4 GPO ports. It has ALC function, that is a Low Power Consumption System realized. It can be developed widely from the high End model to the low End model. As it has charge pump circuit for DCDC, it is no need to use coils, and it contributes to small space. VCSP50L3(3.50mm×3.50mm 0.5mm space) It adopts the very thin CSP package that is the most suitable for the slim phone.
The BD6088GUL is an intelligent LED driver designed for LCD backlights in mobile devices. It supports up to six LEDs, includes an ambient‑light sensor interface, charge‑pump DC/DC conversion, and a 4‑port GPO with thermal shutdown and protection features.
The document lists absolute maximum ratings, detailed electrical characteristics, pin‑out diagrams, package dimensions, and ordering information. Block diagrams and example application circuits illustrate typical usage, while the ordering section specifies the VCSP50L3 package and tape‑and‑reel handling.
