A good PCB layout for the LM5026MTX/NOPB involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the input and output capacitors are of high quality and have low ESR. It's also important to decouple the input voltage with a capacitor and to use a low-impedance output capacitor.
The LM5026MTX/NOPB can handle input voltages up to 42V, but it's recommended to keep the input voltage below 36V to ensure reliable operation and to prevent damage to the device.
The output voltage of the LM5026MTX/NOPB can be calculated using the following formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the feedback resistors, Vin is the input voltage, and Vref is the reference voltage (typically 1.25V).
The LM5026MTX/NOPB can deliver up to 2A of output current, but it's recommended to keep the output current below 1.5A to ensure reliable operation and to prevent overheating.
