AL5816Q
Description
The AL5816Q is a 5-terminal adjustable constant current linear LED controller offering excellent temperature stability and current capability. The AL5816Q can work with a wide input voltage range from 4.5V to 60V. With its low 200m V current sense FB voltage, it controls the regulation of LED current with minimum power dissipation pared with traditional linear LED drivers. This makes it ideal for medium to high current LEDs.

PWM 1
5 VCC
GND 2
The device has an internal output drive up to 15m A, 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.
The AL5816Q has 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 AL5816Q can be dimmed by PWM signal through PWM pin, it can run at...
