Key Differentiators
- Pre-programmed for AM64x processors (vs TPS6521815RSLR)
- Seven output rails in a compact 48-VQFN package (vs TPS6521815RSLR)
- Industrial temperature range -40°C to +105°C (vs TPS6521815RSLR)
Design Notes
Ensure input capacitance is adequate for the chosen input source. For Li-Ion battery input, place a 10uF ceramic capacitor close to the VIN pin. For 5V adapter input, consider a larger bulk capacitor to handle transient loads. Refer to the TPS6521855 datasheet for recommended input capacitance values.
Place output capacitors for each rail close to the respective VOUT pins to minimize parasitic inductance and ensure stable regulation. Use multiple vias to the ground plane for thermal and electrical performance. The 48-VQFN package has an exposed pad that should be soldered to a thermal land for proper heat dissipation.
Do not exceed the absolute maximum input voltage rating. For designs requiring custom power sequencing, use the TPS6521815 instead of the TPS6521855, as the latter is pre-programmed for AM64x. Verify I2C address and communication settings to avoid conflicts in multi-device systems.
