Semiconductor manufacturer ROHM Co., Ltd. has announced the development of an LED driver IC series optimized for portable devices of all types, including mobile phones and car audio equipment. Features include built-in display pattern data and automatic illumination control that lightens CPU load. Two models are offered: the BD2802GU (2.8×2.8×1.0mm) designed to drive 6 LEDs, and the BD2812GU (3.1×3.1×1.0mm) which integrates a boost circuit.
The continuing trend towards greater sophistication in electronic devices has been accompanied by an equally large need for high performance LED illumination. Conventional LED driver ICs normally do not include an illumination control function, making fine gytnrwq gdsthqw fdeyzchvt.
