LTC1147CS8-5#PBF Frequently Asked Questions (FAQ)

  • A good PCB layout for the LTC1147CS8-5 involves keeping the input and output traces short and separate, using a solid ground plane, and placing the bypass capacitors close to the device. A 4-layer board with a dedicated power plane and a dedicated ground plane is recommended.

  • To ensure stability, make sure to follow the recommended compensation network, use a minimum output capacitance of 10uF, and keep the input and output resistors within the recommended range. Also, avoid using long input traces and keep the device away from noise sources.

  • The maximum input voltage that the LTC1147CS8-5 can handle is 15V, but it's recommended to keep the input voltage below 12V to ensure reliable operation and to prevent damage to the device.

  • The LTC1147CS8-5 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.

  • The output voltage ripple of the LTC1147CS8-5 can be calculated using the formula: ΔVout = (Iout * Rout) / (fsw * Cout), where Iout is the output current, Rout is the output resistance, fsw is the switching frequency, and Cout is the output capacitance.
