A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane and ensure good thermal conduction to the surrounding components.
Use a high-quality output capacitor with low ESR, ensure the input capacitor is properly decoupled, and add a 10nF capacitor between the FB pin and GND to reduce noise.
The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
The output voltage accuracy is typically ±2% over the entire operating range. Calculate the output voltage using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the feedback resistors.
A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close as possible to the VIN pin.
