LM3754EVAL/NOPB
| 4-Phase 100A Master/Slave Evaluation Board | Full production
Lead Free (RoHS)
|
| $180.00 each | 1 |
 Description:
The LM3754 evaluation board is designed to provide the design engineer with a fully functional power converter based solution using two LM3754 2-Phase Buck Controllers. This evaluation board produces an output voltage of 1.2 V at 25A per phase for a total of 100A. The switching frequency for the converter is set to 300 kHz per phase, for an effective 1.2 MHz at the input and output. The gate signals for each controller’s outputs are 180 degree out of phase, with the two controllers having a 90 degree phase shift from each other. The printed circuit board consists of 4 layers of FR4 material with 2 ounce copper on all layers.

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.
