MP8761GLE-Z datasheet by Monolithic Power Systems

MP8761GLE-Z Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 4-layer PCB with a solid ground plane and thermal vias connecting the exposed pad to the ground plane is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
• How do I ensure stability and prevent oscillations in the output voltage?
  To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, a low-ESR output capacitor and a minimum of 10uF ceramic capacitor at the output are recommended to prevent oscillations.
• What is the maximum input voltage that can be applied to the device?
  Although the datasheet specifies a maximum input voltage of 26V, it's recommended to limit the input voltage to 24V to ensure reliable operation and prevent damage to the device.
• How do I implement overcurrent protection (OCP) and short-circuit protection (SCP) in my design?
  The MP8761GLE-Z has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the current limit threshold. For SCP, connect the SCP pin to a resistor divider network that sets the short-circuit detection threshold.
• What is the recommended input capacitor type and value for optimal performance?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to filter out noise and ensure stable operation.
