A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise and EMI.
To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor's ESR is less than 1 ohm. Also, avoid using ceramic capacitors with high ESL.
The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
The LV5609LP-E is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
Use an oscilloscope to check the input and output waveforms, and verify the input voltage, output current, and temperature. Check the PCB layout and component values, and ensure proper thermal design and heat sinking.
