A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching node (SW) away from sensitive analog nodes and ensure good thermal conduction to the PCB ground plane.
Use the provided compensation network calculator tool or follow the guidelines in the datasheet to select the correct values for RCOMP, CCOMP, and RFB. The goal is to achieve a stable loop with adequate phase margin.
The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability. Exceeding 28V can cause damage to the device.
Use a soft-start circuit to limit the inrush current during start-up. For shutdown, ensure a controlled ramp-down of the output voltage to prevent voltage spikes and oscillations.
Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 4.7µF and 10µF. This helps to filter input noise and reduce voltage ripple.
