Diodes – AL5815/16 – 60V LED Dimmable Linear Controller
AL5815 and AL5816 are adjustable constant current LED linear 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.
The AL5815 has an enable (ENB) pin. ENB low enables the device; ENB high puts the device into a low quiescent current shutdown state.
If high speed dimming is required the AL5816 has a PWM pin. This device can run at frequencies greater than 20kHz.
AL5815 and AL5816 are available in the SOT25 package.
