MAX756EPA+ datasheet by Maxim Integrated Products

MAX756EPA+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MAX756EPA+ can handle?
  The MAX756EPA+ can handle input voltages up to 12V, but it's recommended to keep the input voltage below 10V for optimal performance and to prevent overheating.
• How do I ensure the MAX756EPA+ is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the distance between the input and output pins.
• What is the minimum input voltage required for the MAX756EPA+ to operate?
  The MAX756EPA+ can operate with input voltages as low as 2.5V, but the output voltage regulation may not be guaranteed below 2.7V. For optimal performance, it's recommended to keep the input voltage above 3V.
• Can I use the MAX756EPA+ in a high-temperature environment?
  The MAX756EPA+ is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper heat sinking to prevent overheating.
• How do I calculate the output voltage of the MAX756EPA+?
  The output voltage of the MAX756EPA+ is adjustable and can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 1.25V to 11V.
