COM OCP8138A High Efficiency Synchronous Boost Converter For 2.
0A WLED Flash ◼ General Description The OCP8138A is a 2MHz fixed frequency synchronous boost converter, optimized for maximum 2.
0A 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 OCP8138A.
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.
One or two LEDs can be connected to the OCP8138A; in the case of two LEDs the output current is matched between each diode.
Thermal regulation is integrated in Flash mode to limit the IC’s temperature and co...
