Vienna 3-Phase Power Factor Correction Reference Design

The Vienna 3-Phase Power Factor Correction Reference Design delivers a high‑efficiency, three‑phase AC‑DC front end for EV and HEV chargers and high‑power industrial applications requiring strict power‑quality compliance. Based on the Vienna rectifier topology, it achieves near‑unity power factor, low iTHD and high power density using a SiC‑optimized power stage capable of 140 kHz switching to reduce passive size. The design delivers up to 98.6% efficiency at 30 kW and uses a dsPIC33AK Digital Signal Controller for high‑bandwidth digital control, accurate grid synchronization and robust protection, including fast overcurrent response. An integrated CAN FD interface supports high‑speed monitoring and diagnostics for modern power platforms.

Automotive Oil Pump Reference Design

The Automotive Oil Pump Reference Design addresses the lubrication and cooling needs of internal combustion, hybrid, and electric vehicles by integrating the motor controller and gate drivers into a compact, single-chip integrated motor driver. Featuring sensor-less Field Oriented Control (FOC) for maximum efficiency and low noise, this solution supports a wide operating range, high power output, and robust CAN communications, making it ideal for oil pumps as well as other automotive applications such as water pumps, A/C systems and fans. This design features a compact, integrated motor driver solution utilizing a 100 MHz dsPIC33CDV256MP506 DSC and MCP8021 gate driver, delivering sensorless FOC control, high efficiency, low noise, and robust performance across a wide operating range, with CAN communication support. 

100V to 12V/2A Non-Isolated Auxiliary Power Supply Reference Design

The 100V to 12V/2A Non‑Isolated Auxiliary Power Supply Reference Design delivers a compact, high‑efficiency synchronous DC‑DC solution for auxiliary and bias rails in industrial, telecom and automotive systems. It supports a wide 14V to 85V operating range with up to 100V maximum input and provides a regulated 12V output at up to 2A, achieving peak efficiency of 95% while delivering 24W. The design features a compact 4.7 × 3.7 cm PCB, a programmable switching frequency, selectable CCM and DCM operating modes, as well as configurable current‑limit protection options. Flexible gate‑drive sourcing helps optimize efficiency and thermal performance in space‑constrained applications.

240W Non-Isolated 1/16th Brick DC-DC with GaN MOSFET Reference Design

The 240W Non‑Isolated 1/16th Brick DC‑DC Reference Design showcases a high‑power‑density solution using Microchip’s COT controller and GaN MOSFET technology. Operating from a wide 36V to 60V input range, it delivers a regulated 12V output at up to 20A with high efficiency at a 400 kHz switching frequency. The design supports on/off control, power‑good signaling, remote sensing and output voltage trim and is built around the MIC2129 controller, EPC2218 GaN FET and a Wurth inductor, making it well suited for applications requiring high current in compact power architectures.

100W Isolated 28V to 48V Flyback Converter Reference Design

The 100W Isolated 28V to 48V Flyback Converter Reference Design provides a flexible, digitally controlled isolated power solution for faster design development. Based on Microchip’s MCP19125 DEPA controller, it supports programmable output voltage (20V–55V), output current, protections and soft‑start via I²C, with onboard monitoring of key operating parameters. Operating from a 20V to 36V input range, the flyback design delivers up to 2A with greater than 80% efficiency, functional isolation between input and output, and an isolated communications interface, making it well suited for industrial and embedded power applications.
