Design Notes

For optimal performance, place the input and output capacitors as close as possible to the IC pins. Use a 10µF ceramic capacitor for input and output, and a 0.1µF capacitor for high-frequency decoupling. The exposed pad should be connected to a large ground plane to improve thermal dissipation.

The LTC3114IDE#PBF can dissipate significant power at high input-output differentials. Ensure adequate copper area on the PCB for heat sinking. The 16-TSSOP exposed pad package has a thermal resistance of approximately 40°C/W; calculate junction temperature to avoid exceeding the 125°C maximum.

Do not exceed the absolute maximum input voltage of 40V. Use a proper input capacitor with low ESR to handle ripple current. The programmable output current (ITHR pin) should be set according to the load requirements; leaving it unconnected may result in higher current limit than intended.
