Description

The BP2831A is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting. The BP2831 integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low. So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.

Description

The EL7L is a high power GaAs IRED mounted In a clear plastic package. With lensed package, this small device has narrow beam angle.

An infrared emitting diode (IR LED) is a type of LED that emits infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. IR LEDs are used in a variety of applications where the emission of IR radiation is required, such as in remote controls, security systems, motion sensors, and medical equipment.

Like other LEDs, an IR LED is a semiconductor device that emits light when a current is passed through it. However, unlike visible LEDs, which emit light in the visible spectrum, IR LEDs emit light in the infrared spectrum. IR LEDs typically emit light at wavelengths between 700 nanometers (nm) and 1 millimeter (mm), which is beyond the range of human vision.

1. Compact ( 3.3mm )

2. Narrow beam angle

3. Low-cost
