AL5812
60V, 150mA ADJUSTABLE LINEAR LED DRIVER
Description
The AL5812 is an adjustable Linear LED driver offering excellent
temperature stability and output handling capability. The AL5812
simplifies the design of linear and isolated or non-isolated LED
drivers by setting the LED current with standard value resistors.
The AL5812 has an open drain output that can swing from 1V up to
60V enabling it drive long LED chains. Its low 0.5V RSET pin is outside
of the LED current path and so accuracy is maintained while
minimizing the required overheads to regulate the LED current. This
reduces its power dissipation when compared to traditional linear
LED drivers. This makes it ideal for driving LEDs up to 150mA
(commonly referred to as ½W LEDs).
Longer LED chains can be driven by tapping VCC from the chain,
where the chain voltage may exceed 60V.
The AL5812 is available in the exposed pad MSOP-8EP and
U-DFN3030-6 packages.

Function
Power Supply Input.
Connect a 0.1μF ceramic capacitor between VCC and GND as close as possible to the
device.
LED Current Setting Pin.
Connect a resistor from this pin to GND:
ILED = 750/RSET
May also be used to provide PWM dimming functionality.
Ground Reference Point of Device.
LED Current Sink Output.
No Connection.
Exposed Pad (bottom).
Used to improve thermal impedance of package.
It must be connected to GND directly underneath the package but not used as sole
GND potential terminal.
