Same-package drop-in variants for temperature grades (vs LTC3114EFE-1#PBF)

Design Notes

For optimal performance, place the input and output capacitors as close as possible to the PVIN and PVOUT pins. Use low-ESR ceramic capacitors (e.g., 10uF) to minimize voltage ripple. The switch node (SW) should have a short, wide trace to reduce parasitic inductance and EMI. The exposed pad must be soldered to a large copper area for heat dissipation.

The LTC3114EFE#PBF can dissipate significant power at high input-output differentials. For example, at VIN=5V, VOUT=12V, and 1A load, the power loss is approximately 7W (assuming 85% efficiency). The 16-TSSOP package with exposed pad has a thermal resistance of about 40C/W; ensure adequate copper area or airflow to keep the junction temperature below 125C.

Do not exceed the absolute maximum input voltage of 40V. Ensure the feedback resistors are 1% tolerance to maintain output accuracy. The RUN pin should be tied to VIN if not used. The ITHR pin sets the average output current limit; leave it floating or connect a resistor to ground to set the desired limit. Incorrect setting can cause premature current limiting or overcurrent damage.
