Description:

450mA 23W Constant Current Buck LED Driver Micro-Module

Features

* 1
* 2 Integrated All Power Components Including the Power Inductor
* Wide Input Voltage Range : 4.5V - 60V
* Constant Switching Frequency at 800kHz
* High Contrast Ratio (Minimum Dimming Current Pulse width < 16µs)
* Drives up to 16 LEDs in series at 60V input

Applications

* with up to 95% power efficiency. It accepts an input voltage ranging from 4.5V to 60V and delivers a 350mA LED current as default. The LED current is adjustable from 300mA to 450mA by charging a single external resistor. The module operates at constant switching frequency (800kHz) with low Electro M
