Power supply layout guidelines.

A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.4 Power Supply Filtering The device Vdd supply pins should be bypassed with low impedance 0.1 µF surface mount capacitors. To reduce EMI, the capacitors should be places as close as possible to the component Vdd supply pins, preferably between the supply pins and the vias connecting to the power plane.

2) POWER SUPPLY DESIGN CRITERIA REQUIRED In order to start the design of the transformer some parameters must be defined from the power supply specification. These are:-1) Minimum operating frequency - f min 2) Estimated power supply efficiency - η ≈ 0.85~0.9 (High Vout), 0.75~0.85 (Low Vout) 3) Minimum DC bus voltage - V minA switch-mode AC-DC power supply. Almost every low-voltage device needs a power supply to function. These devices operate on DC voltage which isn’t directly available from the AC sockets in buildings and our homes. An AC-DC power supply is designed to convert and lower AC mains to a safe and suitable level of DC for low-voltage components.
