MAX1564ETE datasheet by Maxim Integrated Products

MAX1564ETE Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX1564ETE?
  The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 6.3V. A larger capacitor can be used to improve input ripple rejection and transient response.
• How do I ensure the MAX1564ETE is stable and does not oscillate?
  To ensure stability, make sure to follow the layout guidelines in the datasheet, keep the input and output capacitors close to the device, and use a low-ESR output capacitor. Also, avoid using a capacitor with a high ESL (Equivalent Series Inductance) on the output.
• What is the maximum input voltage that the MAX1564ETE can handle?
  The maximum input voltage that the MAX1564ETE can handle is 28V. Exceeding this voltage can cause damage to the device.
• Can I use the MAX1564ETE in a high-temperature environment?
  The MAX1564ETE is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the MAX1564ETE?
  The output voltage of the MAX1564ETE is set by the resistive divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 0.6V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
