LTC3642EDD#PBF datasheet by Linear Technology

LTC3642EDD#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3642EDD#PBF can handle?
  The maximum input voltage that the LTC3642EDD#PBF can handle is 36V, but it's recommended to operate it within the 6V to 24V range for optimal performance.
• How do I ensure the stability of the output voltage in the LTC3642EDD#PBF?
  To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled with a 10uF ceramic capacitor.
• What is the purpose of the SYNC pin in the LTC3642EDD#PBF?
  The SYNC pin is used to synchronize the switching frequency of multiple LTC3642EDD#PBF devices in a system, ensuring that they operate in phase with each other and reducing electromagnetic interference (EMI).
• How do I adjust the switching frequency of the LTC3642EDD#PBF?
  The switching frequency of the LTC3642EDD#PBF can be adjusted by connecting a resistor (RT) between the RT pin and the GND pin. The switching frequency can be calculated using the formula: fSW = 1.25 / (RT x 10^(-6)).
• What is the thermal shutdown temperature of the LTC3642EDD#PBF?
  The thermal shutdown temperature of the LTC3642EDD#PBF is 150°C. When the junction temperature exceeds this value, the device will shut down to prevent damage.
