Follow these general guidelines when designing the power supply:

1. Design the power supply so that it provides the DC voltage, AC noise, and start-up ramp time outlined in the Recommended Operating Conditions section.
2. The DS320PR410 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 a 0.1 µF capacitor per VCC pin, one 1.0 µF bulk capacitor per device, and one 10 µF bulk capacitor per power bus that delivers power to one or more DS320PR410 devices. The local decoupling (0.1 µF) capacitors must be connected as close to the VCC pins as possible and with minimal path to the DS320PR410 ground pad.
