MP3204 详细介绍

MP3204】1.3MHz固定频率5颗白光LED驱动器LED开路保护
MP3204可串联5个白灯. 输入电压2.5V-6V, 最高可耐压30V.反馈电压0.104V。
The MP3204 is a step-up converter designed for driving up to 5 series white LEDs from a single cell Lithium Ion battery. The MP3204 uses current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The MP3204 includes under-voltage lockout, current limiting and thermal overload protection
preventing damage in the event of an output overload. The MP3204 is available in a small 6-pin TSOT23 package.
