产品概述
描述
The EVL80WLED-STCH03 demonstration board implements a wide range 80 W - LED driver for street lighting applications with a primary current sensing control loop. The LED driver is a fixed current source with a very fast start-up time, protections to short-circuit and to open load. The board is optimized to supply an LED string load in the range from 40 V to 80V with a fixed 1 A current source with a very low current ripple.
Due to current primary side STCH03 control loop, the output stage is composed of a simple diode rectification and the output capacitor.
Form factor is compatible with street lighting application.
At full load the efficiency is above the 90% at nominal voltages and remains very close to this value till half the load.
Output short-circuit and no-load protections are auto-restart for a safe operation in lighting environment.
Low input power is there at no-load conditions.
