LMZ14203DEMO/NOPB

| Simple Switcher® Power Module 42Vin, 3A Demonstration Board | Full production Lead Free (RoHS)
|
| $15.00 each | 1 |
The SIMPLE SWITCHER power module demonstration board is optimized for peak performance and small footprint. The output voltage and fast transient response can be adjusted by replacing the small passive components. The good thermal performance of the power modules is showcased using a 2-layer 1oz copper PCB.
Features
- Integrated shielded inductor (inside module)
- VIN = 6V to 42V
- Precision enable UVLO - 8V
- 3.3V output (output voltage is adjustable by changing 1 or 2 resistors)
- Operates at full load up to 80°C ambient at 12V input
- Efficiency
- Up to 92% (LMZ14203/LMZ12003)
- Thermal performance
- θJA = 20°C/W
- θJC = 1.9°C/W
- Uses 0603 passives on back side showcasing production ready layout
- 2.3 in. x 1.7 in. (5.8 cm x 4.3 cm) 2-layer PCB. Uses 1oz copper on top and bottom

LMZ14203EVAL/NOPB

| Simple Switcher ® Power Module 42Vin, 3A Eval Board | Full production Lead Free (RoHS)
|
| $24.00 each | 1 |
The SIMPLE SWITCHER power module evaluation board is optimized for peak performance and increased flexibility. By incorporating additional ceramic and an aluminum filter capacitor, the power module EVAL board demonstrates the low output ripple, fast transient response, and low conducted and radiated EMI performance of the device. Adjusting the output voltage, optimizing the control loop circuitry, and fine-tuning the filter capacitance is ease, with convenient size and placement of the passive components on the board. Finally, the excellent thermal performance of the power modules is enhanced using a 4-layer 1oz copper PCB.

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.
