Richtek exhibited several power management solutions designed for mobile phones and PMP applications at the IIC-China 2005. One of the leading analog IC design company in Taiwan, Richtek manufactures converters, power supervisors and power protectors.

During the show, the company displayed several LED driver ICs for mobile phone backlight applications, including the RT9362, RT9300 and RT9273. "Presently, several backlight sources have been applied, and these light sources have different requirements to the LED driver," said Xingke Dai, an engineer at Richtek.

The RT9362 from Richtek is a driver IC with charge pump and no inductance that can avoid EMI from inductance. Designed for use in color screen's backlighting, this device supports 4 parallel LED simultaneously, with each LED being controlled by GPO separately.

The RT9300 is a low-voltage white LED driver IC designed for low-voltage keypad backlighting, while the single-chip white LED driver RT9273 supports both OLED and TFT/CSTN white LED. The RT9273 is offered in a 3-by-3mm small DFN package, working with only one inductance and two diodes.

All products are already available, with lead times of 4 weeks.
