LM27342MYEVAL
| LM27342MY (10-Pin eMSOP Package) - 2MHz 2A Wide Input Range Step-Down DC-DC Regulator with Frequency Synchronization | Full production
|
| $50.00 each | 1 |
| Description:
The LM27342 demonstration board is designed to provide the power supply design engineer with a fully functional regulator design which can be synchronized to an external clock between 1000 kHz and 2350 kHz. The evaluation board provides a 3.3V output with a 2A current capability. The wide input voltage ranges from 5V to 20V. Without an external synchronization signal, the design operates at 2000 kHz reducing the solution size and keeping switching noise out of the AM radio band. The printed circuit board consists of 4 layers of copper on FR4 material. There is a ground plane on the internal layer directly beneath the LM27342.and a ground plane on the bottom layer. The LM27342 is thermally tied to the ground planes by thermal vias directly underneath the device. The second internal layer is tied half to VIN and half to VOUT.
Features:
- Input Range: 5 to 20V
- Output Voltage: 3.3V
- Output Current: 0 to 2A
- Frequency of Operation: 1000 kHz - 2350 kHz
- Board Size: 1.1 X 1.3 inches

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.
