- Lower output current than TPSM82823 (vs TPSM82823)
Design Notes
Place input and output capacitors as close to the VIN and VOUT pins as possible to minimize parasitic inductance. Use a 10 µF ceramic capacitor for input and a 22 µF ceramic capacitor for output, as recommended in the datasheet. Ensure a solid ground plane for thermal and electrical performance.
The TPSM82822A's µSiP package has limited thermal dissipation capability. For high-current operation, ensure adequate copper area on the PCB to dissipate heat. The datasheet provides thermal resistance values; calculate junction temperature to ensure it stays within limits.
Do not exceed the input voltage range of 5.5 V. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The enable pin must be driven high to start the converter; floating it may cause unpredictable behavior.
