LM36010 LM36010同步升压LED闪光灯驱动器

描述The LM36010 is an ultra-small LED flash driver that provides a high level ofadjustability. With a total solution size of 7 mm2, it can produce up to1.5 A of LED flash current or up to 376 mA of torch current.The device utilizes a 2-MHz or 4-MHz fixed-frequency,synchronous boost converter to power the 1.5-A constant current LED source. An adaptive regulationmethod ensures the current source remains in regulation and maximizes efficiency as it controls thecurrent from 11 mA up to 1.5 A in flash mode or from 2.4 mA up to 376 mA in torch mode.Features of the LM36010 are controlled via an I2C-compatibleinterface. These features include: hardware flash (STROBE) and 128 programmable currents for bothflash and movie mode (torch). The 2-MHz or 4-MHz switching frequency, overvoltage protection (OVP),and adjustable current limit allow for the use of tiny, low-profile inductors and ceramiccapacitors. The device operates over a –40°C to +85°C ambient temperature range.特性Accurate and Programmable LED Currents Flash / IR Currents Ranging from 11 mA up to 1.5 A (128Levels) Torch Currents Ranging from 2.4 mA up to 376 mA(128 Levels) Flash Time-Out up to 1.6 SecondsOptimized Flash LED Current During Low Battery Conditions (IVFM) Grounded Cathode LED Operation for Improved Thermal ManagementSmall Total Solution Size: < 7mm2Hardware Strobe Enable (STROBE)Input Voltage Range from 2.5 V to 5.5V400-kHz I2C-Compatible Interface I2C Address = 0x64All trademarks are the property of their respective owners.
