RH1086MH datasheet by Linear Technology

RH1086MH Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the RH1086MH?
  The maximum input voltage that can be applied to the RH1086MH is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the RH1086MH is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF capacitor between the VIN and GND pins to filter out noise.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms, but it's recommended to use a capacitor with an ESR of 0.05 ohms or less for optimal performance.
• Can I use the RH1086MH in a high-temperature environment?
  The RH1086MH is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent thermal shutdown.
• How do I calculate the output voltage ripple of the RH1086MH?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESR) / (f x C), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and C is the output capacitance.
