NCP1090DRG Frequently Asked Questions (FAQs)

  • A good PCB layout for the NCP1090DRG involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces to reduce EMI. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure stability, make sure the output capacitor is within the recommended range (22uF to 47uF), the input capacitor is at least 10uF, and the feedback resistors are within the recommended range (1kΩ to 10kΩ). Also, ensure the PCB layout is well-designed and the device is properly decoupled.
  • The NCP1090DRG can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The NCP1090DRG is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
  • The output voltage of the NCP1090DRG can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (2.5V), R1 is the feedback resistor connected to the output, and R2 is the feedback resistor connected to the input.
