OCP1201
1.5A flash LED driver for smart phone application
General Description
The OCP1201 is a constant current driver for high
current white LED. Two simple logic control inputs
(ENM and ENF) enable and disable flash and movie
mode operation of the OCP1201.Movie-mode and
Flash-mode, current levels are dependent on the duty
of PWM signal. The maximum current of Flash mode
and movie mode are 1.5A and 0.3A. For Flash mode, a
default timer can be used either to terminate a flash
event or as a safety flash timer. It is an ideal power
solution for WLED photo flash applications within small
PCB layout dimension and used in Lithium-ion/polymer
battery operated products.
The OCP1201 contain over-temperature
shutdown, under voltage lock-out (UVLO) and LED
short to ground protection functions; Built-in circuitry
prevents excessive inrush current during start-up. The
shutdown feature reduces quiescent current to less
than 1.0μA.
The device is available in 6-pin 2mmX2mm DFN
package or in 6-pin TSOT package and is rated over
the -40°C to 85°C.
