LM3401-MR16DEMO/NOPB
| LM3401 MR16 Bulb Reference Design for Non-Dimming & Dimming LED Applications | Full production
Lead Free (RoHS)
|
| $20.00 each | 1 |
 This reference design was based on the released LM3401 evaluation board and associated application note AN- 1657. The circuit and BOM was modified to optimize performance in MR16 solutions. A PCB was created that fits
into the MR16 cavity. For fast bench set-up, the LM3401 evaluation board can be modified with the LM3401 MR16
bill of materials that is listed in the design document.
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 transformer’s maximum rated output current which will degrade the
reliability of the transformer and reduce its operating lifetime. This LM3401 evaluation board is designed to
operate (flicker-free) with common Electronic Low Voltage dimmers, and Electronic Transformers.
This design also generates a constant LED current over most of the power cycle when an electronic transformer is
on versus the short bursts of current applied to an LED stack from the off the shelf LED MR16 bulbs. This results in
better power factor and more stable circuit operation.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
