NCP1521BMUTBG Frequently Asked Questions (FAQ)

  • The recommended PCB layout for the NCP1521BMUTBG is to use a 4-layer board with a solid ground plane, and to keep the input and output capacitors close to the device. Additionally, it's recommended to use a Kelvin connection for the sense pins to minimize noise and improve accuracy.

  • 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 recommended to add a small resistor (e.g. 10Ω) in series with the output capacitor to dampen any potential oscillations.

  • The maximum input voltage that can be applied to the NCP1521BMUTBG is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent damage to the device.

  • The NCP1521BMUTBG is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Additionally, make sure to follow the recommended thermal design guidelines to prevent overheating.

  • To troubleshoot issues with the NCP1521BMUTBG, start by checking the input and output voltages, and ensure that the device is properly powered and configured. Use an oscilloscope to check for any oscillations or noise on the output, and verify that the output voltage is within the expected range. If the issue persists, check the PCB layout and component values to ensure they meet the recommended guidelines.
