Key Differentiators
- Dual 50A or single 100A output capability (vs LTM4650EY#PBF)
- PMBus digital power system management (vs LTM4650EY#PBF)
- Wide input voltage range of 4.5V to 16V (vs LTM4650EY#PBF)
Design Notes
The LTM4700EY#PBF can dissipate significant power at 100A output. Ensure adequate thermal management by using a multi-layer PCB with thermal vias under the BGA package. The datasheet recommends a minimum of 4 layers with 2oz copper for the power and ground planes. Consider adding a heatsink or forced airflow for high ambient temperature operation.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use low-ESR ceramic capacitors for high-frequency decoupling. The datasheet provides recommended capacitor values and placement guidelines. Ensure the PCB layout supports high current paths with wide traces and multiple vias.
Do not exceed the maximum input voltage of 16V. Ensure the PMBus address is correctly configured using the address pins. The FAULT pins are open-drain and require pull-up resistors. Minimize capacitance on the address pin to ensure accurate detection. Follow the datasheet's layout guidelines to avoid noise issues.
Compliance Information
