EUP2468-1.5A Synchronous Boost LED Flash Driver with I2C Compatible Interface 

Description
The EUP2468 is a 2MHz or 4MHz fixed frequency, current mode synchronous boost converter with two current sources. The device is designed to operate 1.5A constant current driver for single channel.
An industry-standard I2C serial digital input is used to enable, disable and set the current for flash LED. The EUP2468 has four logic inputs including a hardware Flash Enable (STROBE), a Flash Interrupt input (TX), a hardware Torch Enable (TORCH/TEMP), Acitve High Enable (HWEN). In flash mode, the LED current source provides target current levels from 21.8mA to 1.5A. And also in torch mode, the programmable current ranges from 1.954mA to 358mA.
The EUP2468 contains serveral protect functions in abnormal conditions such as: Overvltage Protection, Current Limit, NTC Monitoring Protection, Undervoltage Lockout Protection, Thermal Shutdown Protection and LED/OUT short Protection. Built-in circuitry prevents excessive inrush current during start-up. The chip's quiescent current is less than 1.0μA in shutdown mode.
EUP2468 is available in a small 12-bump WCSP package.
