Ordering Information
Description
The XA6050 is the ideal power solution for flash
LEDs used with cell phone camera modules or
digital still cameras. It is a highly integrated
linear flash LED driver, providing a very small
total solution for portable photo flash with
minimum external components. The XA6050
has a flash-mode and movie/torch-mode
switching pin for maximum flexibility. The
flash-mode and movie/torch-mode LED current
is programmed by external resistors
respectively, making the flash LED solution
simple to control.
The LED output can drive flash LEDs up to
700mA continuous LED current.
Various protection features are built into the
XA6050, LED fault (short circuit) protection and
thermal shutdown protection. The leakage
current in shutdown mode is 0.1μA.
The XA6050 is available in a RoHS compliant
DFNWB2 2-8L Package.
