General Description

The BCT3144 is a dual LED flash driver that provides a high level of adjustability within a small solution size.

The BCT3144 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 BCT3144 boost can deliver is 1.5A (ILED1+ ILED2).

Overview

BCT3144 High Efficiency Synchronous Boost Converter With Dual Independent 1.5A Current Sources BCT3144 High Efficiency Synchronous Boost Converter With Dual Independent 1.

Key Features

of the BCT3144 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 programmable currents in each output leg to drive the LEDs in a Flash or Movie Mode (Torch) condition. The 2-MHz or 4-MHz switching frequency options, over voltage protection (OVP), and adjustable current limit allow for the use of tiny, low-profile inductors and (10-µF.
