ANALOG DEVICES ADP1653ACPZ-R7 发光二极管驱动器, 1输出, 升压逐步上升, 3V-5.5V输入, 1.2MHz开关, LFCSP-16
The is a very compact high efficiency high power camera Flash LED Driver optimized for cellular phones. The high efficiency and dynamic LED current control of the device improve flash brightness and picture quality in dimly lit environments. Efficiency peaks at 92% and is higher than charge pump solutions over the Li-Ion battery range. The device has a dual-mode interface that is configurable to 2-bit logic or an I²C® interface. The indicator and high power LED currents are programmable with external resistors or through the I²C interface. To maximize overall flash brightness, the ADP1653 offers an input to reduce flash LED current in less than 50µs, referred to as the Tx mask. Tx masking reduces battery stress by scaling back flash LED current during an RF transmission. The part integrates multiple safety features such as soft start, flash timeout, output current limit, thermal protection and over-voltage protection.
