MOSFET power blocks

Save space, improve efficiency, and simplify power supply design

Our power blocks combine optimized control and synchronous MOSFETs with PowerStack™  packaging technology to eliminate parasitics and achieve higher efficiency. The power block portfolio consists of devices for general power supply and devices that pair with our motor drivers to deliver a complete solution for cordless power tools and appliances.

Power block for power supply

Our power blocks integrate two MOSFETs into a single PowerStack™ package that eliminates parisitic inductance and improves efficiency. These devices operate seamlessly with our synchronous buck and boost controllers.

Power block for motor control

Three devices share a single switch node for a simplified layout of our motor control power blocks. Additionally, our DualCool™ package reduces PCB space by 50% and enables high current capability with ultra-low on resistance to minimize conduction
