Overview

NEW PRODUCT AL5815/AL5816 60V LINEAR LED CONTROLLER Description The AL5815 and AL5816 are 5-terminal adjustable constant current linear LED controllers offering excellent temperature stability and current capability.
They can work with a wide input voltage range from 4.
5V to 60V.
With its low 200mV current sense FB voltage, it controls the regulation of LED current with minimum power dissipation compared with traditional linear LED drivers.
This makes it ideal for medium to high current LEDs.
The device has an internal output drive up to 15mA, which enables it to drive external Bipolar transistors or MOSFETs.
It also provides the capability to drive longer LED chains with low drop out voltage and multiple LED channels.
AL5815 and AL5816 have their LED current adjusted and controlled by a sense resistor connected across FB pin and GND.
The voltage across this resistor is controlled to a precise 0.
2V thus controlling the current.
The AL5815 has an enable (ENB) pin.
Bringing ENB low to ...
