MAX1562HESA+ datasheet by Maxim Integrated Products

MAX1562HESA+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX1562HESA+?
  The recommended PCB layout for the MAX1562HESA+ involves placing the input capacitors close to the VIN pin, and the output capacitors close to the VOUT pin. Additionally, the PCB should be designed to minimize noise and EMI.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, and to choose a capacitor with a low ESR (Equivalent Series Resistance). Additionally, the output voltage can be adjusted using the FB pin.
• What is the maximum input voltage that the MAX1562HESA+ can handle?
  The MAX1562HESA+ can handle a maximum input voltage of 28V. However, it is recommended to operate the device within the specified input voltage range of 7V to 23V for optimal performance.
• How do I protect the MAX1562HESA+ from overcurrent conditions?
  The MAX1562HESA+ has a built-in overcurrent protection (OCP) feature that limits the output current to a maximum of 3.5A. Additionally, it is recommended to add external overcurrent protection devices, such as fuses or PTC thermistors, to protect the device from excessive current.
• What is the thermal shutdown temperature of the MAX1562HESA+?
  The thermal shutdown temperature of the MAX1562HESA+ is typically 150°C. When the device temperature exceeds this threshold, it will shut down to prevent damage.
