Description:The MSDW1000 series is a range of isolated 2W DC-DC converter modules featuring fully regulated output voltages and wide 2:1 input voltage ranges. The products come in a compact SMD package with a small footprint and low package height of just 0.31 inch.
Minmax recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A minimum of 1 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal interface material.
Minmax recommends following the recommended soldering profile, using a solder with a melting point below 260°C, and avoiding excessive soldering temperatures or times. The device should be handled with care to avoid mechanical stress, and the recommended storage conditions should be followed to prevent moisture absorption.
Minmax recommends using low-ESR capacitors with a value of 10uF to 22uF for the input and output capacitors. The capacitors should be placed as close as possible to the device pins, and the PCB layout should be designed to minimize parasitic inductance and resistance.
Minmax recommends checking the input voltage, output load, and PCB layout for any issues. Verify that the device is properly soldered and that the thermal management is adequate. Use an oscilloscope to monitor the output voltage and current, and check for any signs of oscillation or instability. Consult the datasheet and application notes for troubleshooting guidelines and contact Minmax technical support if necessary.
Minmax recommends using a high-quality, low-noise input voltage source with a minimum voltage rating of 1.5 times the maximum input voltage of the MSDW1012. The input voltage source should be able to provide a minimum current rating of 1.5 times the maximum input current of the device.
