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.

LM3450AEV230V30: 700mA @ 45V Max, 180 ~ 265 VAC

Manufacturer: Texas Instruments

The LM3450A evaluation board is designed to provide an AC to LED solution for a 30 W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 700 mA for a series string of 1 to 13 LEDs (maximum LED stack voltage of 45 V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120 VAC or 230 VAC.

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…

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.

LM3404HVEVAL: 1A @ Vin Max, 6 ~ 75V in

Manufacturer: Texas Instruments

The LM3404HV circuit and BOM have been designed to provide a constant forward current of 1.0A to a single LED with a forward voltage of approximately 3.7V from an input of 48V ±10%. Over the input voltage range of 6V to 75V the average LED current, IF, is 1.0A ±10%, the ripple current, ΔiF, will not exceed 400 mAP-P, and the switching frequency is 200 kHz ± 10%.

ZXSC400EV4: 1 LED @ 350mA, 1.8 ~ 3 Vin

Manufacturer: Diodes Incorporated

The ZXSC400 is voltage mode boost converter in SOT23-6 package. Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor with minimal losses. The ZXSC400EV4 is configured as a boost converter to drive a 1W LED from two NiCd / NiMH batteries.
