Follow these general guidelines when designing the power supply:
- The power supply should be designed to provide the recommended operating conditions outlined in Specifications in terms of DC voltage, AC noise, and start-up ramp time.
- The maximum current draw for the DS280BR820 is provided in Specifications. This figure can be used to calculate the maximum current the supply must provide. Typical mission-mode current draw can be inferred from the typical power consumption inSpecifications.
- The DS280BR820 does not require any special power supply filtering, such as ferrite beads, provided the recommended operating conditions are met. Only standard supply decoupling is required. Typical supply decoupling consists of a 0.1-μF capacitor per power pin, and single 1.0-μF and 10-μF bulk capacitors.
