5A High Efficiency Synchronous Boost Flash LED Driver With 1-Wire Flash Dimming ◼ General Description The OCP8135 is a 2MHz fixed frequency synchronous boost converter, optimized for maximum 1.
5A camera flash application and maximum 800mA movie mode applications using high-current white LEDs in all single cell Li-ion powered products.
An adaptive regulation method ensures the current for each LED remains in regulation and maximizes efficiency.
Two simple logic control inputs (ENM and ENF) enable and disable flash and movie mode operation of the OCP8135.
Movie-mode and Flash-mode current levels are independently fixed by two separate resistors (RM and RF).
For Flash mode, a default timer can be used either to terminate a flash event or as a safety flash timer.
In flash mode, the flash LED current can be programmed in 16 steps by the 1-wire dimming interface at ENF pin.
One or two LEDs can be connected to the OCP8135; in the case of two LEDs the output...
