LM3401EVAL
用于高功率 LED 驱动的 LM3401 滞后 PFET 控制器评估模块
LM3401EVAL
概述
The LM3401 is a switching buck regulator derived current source designed to drive a series string of high power, high brightness LEDs. The LM3401 controls an external P-FET, allowing the user to select a power device for the desired level of forward LED current. The LM3401 demo board can supply continuous current as high as 1.0A from an input voltage range of 4.5V to 35V. It is designed to operate at ambient temperatures up to 75°C.
