RECOM recommends a PCB layout with a large copper area (at least 1 inch²) connected to the module's thermal pad, and multiple vias to dissipate heat to the bottom layer. A thermal interface material (TIM) can also be used to improve heat transfer.
To ensure reliability, RECOM recommends operating the module within the specified temperature range (-40°C to +85°C). Additionally, consider derating the output power and using a heat sink or forced air cooling to keep the module temperature below 80°C.
RECOM recommends using a low-ESR ceramic capacitor (X7R or X5R dielectric) with a value of 10-22 μF, placed as close as possible to the module's input pins. This helps to filter input noise and ensure stable operation.
Yes, the RKZ3-0505S/H can be used in redundant or parallel configurations, but RECOM recommends consulting their application notes and performing thorough testing to ensure reliable operation and avoid potential issues with synchronization or current sharing.
The RKZ3-0505S/H has a built-in undervoltage lockout (UVLO) that shuts down the module when the input voltage falls below 2.5 V. The module will automatically restart when the input voltage recovers to a level above 3.5 V.
