8.3 Power Supply Recommendations

Follow these general guidelines when designing the power supply:

  1. The power supply should be designed to provide the operating conditions outlined in the recommended operating conditions section in terms of DC voltage, AC noise, and start-up ramp time.
  2. The DS160PR1601 does not require any special power supply filtering, such as ferrite beads, provided that the recommended operating conditions are met. Only standard supply decoupling is required. Typical supply decoupling consists of adequate numbers of 0.1 µF capacitors near device VCC pins, several 1.0 µF and 10.0 bulk capacitors on VCC power plane. The local decoupling (0.1 µF) capacitors must be connected as close to the VCC pins as possible and with minimal path to the DS160PR1601 ground pad. For more specific guidance, refer to DS320PR1601RSC-EVM User's Guide.
