The LMR10530 evaluation module is designed to provide the power supply design engineer with a fully functional regulator
design using the LMR10530 3 MHz switching regulator in an LLP-10 package. The evaluation module is configured to provide
an output of 1.2V at up to 3A from an input voltage range of 3V to 5.5V.
The printed circuit board consists of 4 layers of copper on FR4 material. The middle layers are solid ground layers with the first
middle layer having a small polygon cut out for the VIN node. The intermediate ground layer helps in minimizing the AC current
loop. The LMR10530 is thermally tied to the other layers by thermal vias directly underneath the device. This user's guide
contains the evaluation module schematic, a quick setup procedure, and a Bill-of-Materials (BOM). Refer to the LMR10530
datasheet for complete circuit design information.
The module has a Cff capacitor footprint reserved for applications requiring higher VOUT. The Cff cap also helps to minimize the
output voltage overshoot during sluggish startup. Please refer to the LMR10530 datasheet for suggested cap values. The
module also has a reserved footprint for an additional output cap, Co2, for certain applications requiring more capacitance.
