Description:The MA03 series is a range of isolated 3W DC-DC converter modules in a small SIP-package. There are 12 models available with 5V, 12V or 24VDC input. These products have a typical load regulation of 5.0% to 7.0% depending on model.
The recommended PCB layout involves placing the DC-DC converter near the power source, using a solid ground plane, and keeping the input and output capacitors close to the converter. For thermal management, ensure good airflow, use a heat sink if necessary, and follow the recommended operating temperature range.
To ensure EMC, follow proper PCB design and layout guidelines, use shielding if necessary, and ensure the converter is placed at least 10mm away from other components. Additionally, use a common-mode choke and filter capacitors to reduce EMI.
The maximum allowable capacitance for the input capacitor is 220uF, and for the output capacitor, it is 100uF. Exceeding these values may affect the converter's stability and performance.
Yes, the MA03-12S05 is designed to withstand vibrations up to 10G. However, it's essential to ensure the converter is properly secured to the PCB and the PCB is securely fastened to the system to prevent damage or dislodging.
To ensure reliable operation, it's recommended to derate the input voltage by 10% to account for voltage drops and tolerances. For example, if the input voltage is 12V, use a derated value of 10.8V.
