Frequently Asked Questions
Can the LM5113SDE drive GaN FETs, and what gate current does it deliver for fast switching?
Yes. The LM5113SDE is specifically optimized for GaN FET gate drive, providing up to 5 A peak output current to charge and discharge gate capacitances quickly. This supports high switching frequencies in DC-DC converters operating at up to 100 V, minimizing switching losses.
What topology does the LM5113SDE support, and how does its high-side bootstrap work up to 100 V?
The LM5113SDE supports a half-bridge topology with a bootstrap-based high-side driver rated to 100 V. The bootstrap capacitor charges during the low-side on-time, allowing the high-side gate drive to float up with the switching node and reliably turn on the top FET at high supply voltages.
How does the Schmitt trigger input of LM5113SDE benefit noisy power converter PCB environments?
The Schmitt trigger input structure provides hysteresis on the logic threshold, rejecting high-frequency noise and dV/dt coupled transients common in half-bridge power stages switching at 100 V. This prevents false triggering of the gate driver during fast switch-node transitions without requiring additional RC filtering.
What is the package type and pin count of the LM5113SDE, and how does it affect thermal management in power designs?
The LM5113SDE comes in a WSON-10 (S-PDSO-N10) 10-pin surface-mount package with an exposed thermal pad. The compact package reduces parasitic inductance in the gate drive loop and allows the thermal pad to provide a direct heat conduction path to the PCB copper pour, aiding thermal management at high switching currents.
