- About SGMICRO
The SGM37864 is a dual LED flash driver that is compact and highly customizable. It employs a synchronous Boost converter with a fixed frequency of 2MHz or 4MHz to drive the dual constant current LED sources, each up to 2A. The dual current sources, each with 256 levels, allow for flexible adjustment of the current ratios between LED1 and LED2. The utilization of an adaptive control method ensures that the current sources are regulated and efficiency is maximized.
The device's features include an I2 C interface for management, hardware flash and torch pins (STROBE and TORCH/TEMP), an NTC thermistor monitor, and a TX interrupt. The LEDs can operate in either flash or torch mode, with independently programmable currents in each output leg.
The SGM37864 also includes options for 2MHz or 4MHz switching frequency, adjustable current limit, input voltage flash monitor (IVFM) and over-voltage protection (OVP), making it possible to use small, low-profile inductors and 10µF ceramic capacitors. It operates within a temperature range of -40℃ to +85℃.
