WWW.ORIENT-CHIP.COM OCP81373 High Efficiency Synchronous Boost Converter With Dual Independent 1.5A Current Sources ◼ General Description The OCP81373 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The OCP81373 utilizes a 2-MHz or 4-MHz fixed-frequency synchronous boost converter to provide power to the dual 1.5A constant current LED sources. The total LED current the OCP81373 boost can deliver is 1.5A (ILED1+ ILED2). The dual 128 level current sources provide the flexibility to adjust the current ratios between LED1 and LED2 with each driver capable of delivering a maximum of 1.5A. An adaptive regulation method ensures the current sources remain in regulation and maximizes efficiency.
