NCV494BDR2G Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the NCV494BDR2G is -40°C to 150°C.
  • To ensure proper biasing, connect the input pins (VIN) to a stable voltage source, and decouple the output pins (VOUT) with a capacitor to ground. Also, ensure the input voltage is within the recommended range (4.5V to 18V).
  • To minimize EMI, use a multi-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a shielded inductor. Also, place the input and output capacitors close to the device.
  • To calculate the output voltage ripple, use the following formula: ΔVOUT = (IOUT * RLOAD) / (fSW * COUT), where IOUT is the output current, RLOAD is the load resistance, fSW is the switching frequency, and COUT is the output capacitance.
  • The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 25V or higher, and an ESR of 0.1Ω or less.
