LM3401-MR16DEMO: 1A @ 6.2V Max, 12VAC, MR16

Manufacturer: Texas Instruments

This design was developed to minimize the current spikes coming out of an electronic transformer to less than 5A, which is a typical transformer rating, when driving an LED MR16 circuit. The off the shelf LED MR16 solutions exhibit spikes that significantly exceed a transformers maximum rated output current which will degrade the reliability of the transformer and reduce its operating lifetime. T…

EVL130W-STRLIG(1): 48V @ 2.7A, 85 ~ 305 VAC

Manufacturer: STMicroelectronics

* For Constant Current, the board must be modified as described on page 8 of the user guide. * Streetlight applications require that the power supply designed to power an LED lamp must have high efficiency and at least an equivalent lifetime in order to guarantee maintenance-free operation during the life of the LED.

EVL6562A-LED: 350mA @ 45V Max, 36 ~ 60V in

Manufacturer: STMicroelectronics

Whenever a lighting application, such as street lighting for example, requires an elevated number of LEDs, there are basically two solutions: the first is to connect all the diodes in series in a single "string"; the second is to place several strings in parallel with fewer elements in each one.

STEVAL-ILL016V2: 350mA, 700mA, 1A @ 40V Max, TRIAC

Manufacturer: STMicroelectronics

This application note presents a low-cost driver for LEDs that is compatible with TRIAC phase-control dimmers. The design gives luminaire manufacturers a low-cost, commonly available dimming option for home fixtures. A side benefit is that, when not wired to a dimmer, the unit's power factor is over 0.9. The design is based on the L6562A transitionmode PFC controller driving a single stage PFC-fl…
