Analog Devices Introduces New LED Flash Driver for Camera-Enabled Phones

Analog Devices (ADI) has added a new 1500-mA white LED driver, the ADP1650, to its inductive-based flash driver devices, and power management line. The ADP1650 has several features such as a 4-bit ADC, two separate TxMASK inputs, a programmable I²C interface, and a programmable flash and torch currents up to 1500 mA for single LED.

The ADP1650 LED driver offers 85% high efficiency at a battery voltage at 90% peak. The driver is offered in a 12-ball WLCSP package. The compact LED driver decreases the battery current draw and increases the input power to LED power conversion during flash processes, to deliver efficient operation on any battery voltage. The ADI LED driver uses the limited battery current meant for flash, hence, it connects to the advanced image processors and sensors easily, offering remarkable picture quality in low light.

Analog Devices’ technical director of Power Management Technology Group, Jose Rodriguez, stated that the customers consider camera quality as one of the main feature while choosing a mobile phone. A quality flash is essential, as camera phones are often used to take images in dim light, or during talking.
