In the first of two PCIM interviews with Tomás from Monolithic Power Systems (MPS), ipXchange learns about MPS’ high-power AC/DC IC solutions. In this example, these devices are being used to control a highly efficient 3 kW totem pole + LLC reference design.
This datacentre solution uses silicon carbide MOSFETs for fast switching at up to 100 kHz, and these devices are controlled by MPS’ MPF32010 digital totem-pole controller that features an integrated GUI for easy parameter configuration, resulting in faster time-to-market for your design. Under normal conditions, the power factor of this design is greater than 99%, and the efficiency is greater than 98.5% for 1 kW output and above.
With supporting gate drivers and current sensor ICs, MPS provides the complete solution for integrating their high-power components, which can be used in a wide range of applications including automotive, datacentres, renewable energy, and uninterruptable power supplies.
Keep designing!
