RH1011W datasheet by Linear Technology

RH1011W Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the RH1011W?
  The RH1011W can withstand input voltages up to 60V, but it's recommended to limit the input voltage to 40V for reliable operation.
• How do I ensure the RH1011W is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 100nF capacitor between the VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the RH1011W to operate?
  The RH1011W can operate with input voltages as low as 7V, but the output voltage regulation may not be guaranteed below 8V.
• Can I use the RH1011W in a high-temperature environment?
  The RH1011W is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
• How do I calculate the output voltage of the RH1011W?
  The output voltage (VOUT) can be calculated using the formula: VOUT = (R1 / R2) * (VIN - VREF), where R1 and R2 are the resistors connected to the FB pin, VIN is the input voltage, and VREF is the internal reference voltage (1.25V).
