GENERAL DESCRIPTION  
The ADP1650 is a very compact, highly efficient, single white  
LED flash driver for high resolution camera phones that  
improves picture and video quality in low light environments.  
The device integrates a programmable 1.5 MHz or 3.0 MHz  
synchronous inductive boost converter, an I2C-compatible  
interface, and a 1500 mA current source. The high switching  
frequency enables the use of a tiny, 1 mm high, low cost, 1 µH  
power inductor, and the current source permits LED cathode  
grounding for thermally enhanced, low EMI, and compact  
layouts.  
conversion and minimize battery current draw during flash  
events. A programmable dc battery current limit safely maximizes  
LED current for all LED VF and battery voltage conditions.  
Two independent TxMASK inputs permit the flash LED current  
and battery current to reduce quickly during a power amplifier  
current burst. The I2C-compatible interface enables the pro-  
grammability of timers, currents, and status bit readback for  
operation monitoring and safety control.  
The ADP1650 comes in a compact 12-ball, 0.5 mm pitch  
package and operates within specification over the full −40°C to  
+125°C junction temperature range.  
The LED driver maximizes efficiency over the entire battery  
voltage range to maximize the input-power-to-LED-power
