9 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 DS160PR412 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 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 device

ground pad.

3. The DS160PR412 voltage regulator output pins require decoupling caps of 0.1 µF near each pins. The

regulator is only for internal use. Do not use to provide power to any external component.
