Analog Devices, Inc. (ADI), a global leader in high-performance
semiconductors for signal-processing applications, today introduced
two flash LED drivers. The ADP1660 is a dual 750-mA (1500-mA total)
flash LED driver available in a 2.0-mm x 1.6-mm 12-ball WLCSP
package. The ADP1649 is a single 1000-mA LED driver available in a
2.0-mm x 1.5-mm 12-ball WLCSP package. Both parts exhibit best in
class efficiency to extend battery life in smartphones and tablets
and to limit the load on the battery during flash and torch
events.

“Minimizing the current drawn from the battery during flash or
torch mode is critical in today’s smartphone applications as new
features and higher data rates increasingly load down the battery,”
said Brian Wengreen, marketing manager, Power Management Products,
Analog Devices. “The ADP1649 and ADP1660 not only have the
industry’s lowest Rds(on) power FETs, which boosts efficiency and
reduces input current, they also have special features, for example
algorithms that adjust flash current autonomously during low
battery conditions.”
More About the ADP1649/ADP1660 Flash LED Drivers
The ADP1649 and ADP1660 flash LED drivers reduce circuit board
size by integrating a programmable 1.5-MHz or 3-MHz synchronous
inductive boost converter which enables the use of a 1-mm-high,
low-cost, 1-μH power inductor and 0603 case-size input and output
capacitors. The two devices include I²C communication ports for
added flexibility and safety control. The interface also enables
the programmability of timers, currents and status bit
readback.
A Tx masking feature is included to reduce the risk of
overloading the battery during a simultaneous power amplifier (PA)
transmission burst and flash event. The masking feature can be used
to quickly reduce the flash LED current during the PA burst to
maintain an acceptable load on the battery.
