Murata recommends a PCB layout with a solid ground plane, minimal thermal resistance, and adequate clearance around the module. A thermal interface material (TIM) with a thermal conductivity of 1-2 W/m-K is recommended between the module and the heat sink. The heat sink should have a thermal resistance of ≤ 1°C/W.
To ensure reliable start-up and operation, Murata recommends using a soft-start circuit to limit the inrush current, and a bulk capacitor with a low equivalent series resistance (ESR) to minimize voltage droop. The output filter should be designed to meet the recommended output impedance and stability criteria.
Murata provides derating curves for temperature, input voltage, and output current in the application notes or upon request. These curves help engineers determine the module's performance and reliability under various operating conditions.
Murata recommends using external OVP and UVP circuits to protect the module from input and output voltage faults. The OVP and UVP circuits should be designed to meet the recommended voltage thresholds and response times.
Murata recommends using input and output filters with a combination of capacitors, inductors, and resistors to meet the recommended electromagnetic interference (EMI) and electromagnetic compatibility (EMC) standards. The filter components and configurations should be designed to meet the specific application requirements.
