- Pin-compatible with TPS53622RSBR (vs TPS53632RSBR)
Design Notes
Place the TPS53622RSBT close to the power stage MOSFETs to minimize parasitic inductance in the PWM and sense traces. Use a solid ground plane and place decoupling capacitors (0.1uF and 1uF) near the VIN and VDD pins. For the PMBus lines, add pull-up resistors as specified in the datasheet. Ensure the exposed thermal pad is soldered to a large copper area for heat dissipation.
The TPS53622RSBT requires a bootstrap capacitor for each phase (BOOT1 and BOOT2). Use a 0.1uF ceramic capacitor rated for at least 25V. The input supply should be decoupled with bulk capacitors (e.g., 10uF) and high-frequency ceramic capacitors (0.1uF) to handle transient currents. The output voltage sense lines should be routed as Kelvin connections to the load to avoid voltage drops.
The TPS53622RSBT's power dissipation is primarily in the external power stages, but the controller itself generates heat. The WQFN-40 package has an exposed thermal pad that must be connected to a copper pour. For high-current applications, ensure adequate airflow or heatsinking. The operating temperature range is -40Β°C to 125Β°C, so verify the junction temperature stays within limits under worst-case conditions.
