Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the IC. The input and output tracks should be kept short and away from noise sources. A decoupling capacitor of 10uF or more should be placed close to the IC.
To ensure reliability in high-temperature applications, it is recommended to follow Panasonic's derating guidelines for the IC. The operating temperature range should be limited to 85°C or lower, and the power dissipation should be reduced accordingly. Additionally, the PCB should be designed to minimize thermal resistance and ensure good heat dissipation.
Panasonic recommends a soldering profile with a peak temperature of 260°C or lower, and a dwell time of 10-30 seconds. The soldering process should be done in a nitrogen atmosphere to prevent oxidation. It is also recommended to use a solder with a melting point of 217°C or higher.
To troubleshoot issues with the ASQ10618, it is recommended to check the input voltage, output voltage, and current consumption using an oscilloscope and a multimeter. The PCB layout and component placement should be verified to ensure that they meet Panasonic's recommendations. The input and output capacitors should be checked for their values and ESR. If the issue persists, it is recommended to contact Panasonic's technical support for further assistance.
Panasonic recommends an input capacitor with a value of 10uF or more, and an ESR of 100mΩ or less. The capacitor should be a low-ESR type, such as an X5R or X7R ceramic capacitor, and should be placed close to the IC.
