EV3213DH-00B

The EV3213DH-00B is a Low Noise Block (LNB) power supply evaluation board for the MP3213. It is configured to provide a digitally switchable 13.2V or 19.5V output at up to 0.5A from a 12V input. The output is set to 13.2V when EN2 is low and 19.2V when EN2 is high. The circuit also provides output disconnect when EN1 is low and overload and short circuit protection.

The high switching frequency (700kHz or 1.3MHz) of the MP3213 allows for smaller external components, producing a compact solution for a wide range of load currents. Two user selectable frequency options offer flexibility for easy filtering and low noise. The PCB heatsink with the exposed pad improves thermal performance and efficiency at medium to heavy loads.
