Bel Power Solutions recommends a PCB layout with a solid ground plane and a minimum of 2 oz copper thickness to ensure optimal thermal performance. Additionally, keeping the components away from the power converter and using thermal vias can help to reduce thermal resistance.
To ensure reliable start-up and operation with a low input voltage, it is recommended to add a soft-start circuit to reduce the inrush current and to use a bulk capacitor with a low ESR value to filter the input voltage. Additionally, the input voltage should be monitored and the converter should be shut down if it falls below the minimum specified voltage.
The maximum allowed capacitance on the output of the AM1001-7P is 2200uF. Exceeding this value can cause instability and affect the reliability of the converter.
The AM1001-7P has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. Additionally, an external current sense resistor can be used to monitor the output current and shut down the converter if it exceeds the maximum allowed value.
The recommended fuse rating for the input of the AM1001-7P is 5A slow-blow. This ensures that the fuse can handle the inrush current during start-up and provides protection against overcurrent faults.
