A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the device.
Use a soft-start circuit to limit the inrush current during startup. For shutdown, ensure a controlled shutdown sequence to prevent voltage spikes and oscillations.
Use a common-mode choke, X-capacitors, and Y-capacitors to filter EMI. Ensure the filter components are placed close to the device and the PCB layout is optimized for EMI reduction.
Use a low-standby-power controller, such as the NCP1031, and optimize the design for low quiescent current. Ensure the device is in a low-power state during standby mode.
Use a heat sink with a thermal resistance of <1°C/W. Ensure good thermal contact between the device and heat sink. Consider using thermal interface material and a fan for forced convection cooling.
