OCP8136

WWW.ORIENT-CHIP.COM OCP8136 High Efficiency Dual Color Temperature Dimming Dual-1.2A Flash LED Driver With Separate 1-Wire Flash Dimming ◼ General Description The OCP8136 is a dual-channel 2MHz fixed frequency synchronous boost converter, optimized for maximum 2.4A(1.2A/channel) camera flash application and maximum 1000mA (500mA/channel) 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. The dual-channel flash LED drivers are independent. ENM1 and ENF1 pins control channel 1 flash LED driver; ENM2 and EMF2 pins control channel 2 flash LED driver. Two simple logic control inputs (ENM1/2 and ENF1/2) enable and disable flash and movie mode operation of the OCP8136. Movie-mode and Flash-mode current levels are independently fixed by two separate resistors (RSETM1/2 and RSETF1/2). For Flash mode, a default timer can be used either...
