OCP81372

WWW.ORIENT-CHIP.COM OCP81372 High Efficiency Synchronous Boost Converter With Dual Independent 1.5A Current Sources ◼ General Description The OCP81372 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The OCP81372 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 OCP81372 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. Features of the OCP81372 are controlled via an I2C-compatible interface. These features include: hardware flash and hardware torch pins (STROBE and TORCH/TEMP), a TX interrupt, and an NTC thermistor monitor. The device offers independently progr...
