PAM2861ABR datasheet by Diodes Incorporated

PAM2861ABR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
• How do I ensure stable output voltage regulation?
  To ensure stable output voltage regulation, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, decoupling capacitors should be placed close to the IC, and the input capacitor should be a low-ESR type.
• What is the maximum input voltage that can be applied to the PAM2861ABR?
  Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the IC.
• Can I use the PAM2861ABR in a high-temperature environment?
  While the PAM2861ABR is rated for operation up to 85°C, it's essential to consider the thermal derating curve and ensure that the IC does not exceed the maximum junction temperature (150°C) to prevent damage or malfunction.
• How do I troubleshoot issues with the PAM2861ABR?
  To troubleshoot issues, start by verifying the input voltage, output voltage, and current consumption. Check for proper PCB layout, component values, and decoupling capacitor placement. If issues persist, consult the datasheet and application notes or contact Diodes Incorporated's technical support.
