GaN Switching Frequency: Using Gallium Nitride Technology in Next-Generation High-Frequency Circuits

Renee Yawger, Director of Marketing

Gallium nitride (GaN) is a very hard, mechanically stable wide bandgap semiconductor that is used in the production of power devices as well as RF components and light-emitting diodes (LEDs). GaN switching frequency is substantially higher than silicon, enabling power electronics designers to create smaller, more efficient, and higher-performing systems that were previously challenging to achieve with silicon technologies.

eToF™ Laser Driver ICs for Advanced Autonomy Lidar

John Glaser , Ph.D., Director of Applications

Co-written by Steve Colino

Laser drivers for light distancing and ranging (lidar) are used in a pulsed-power mode. What are the basic requirements for these laser drivers?

A new family of integrated laser driver ICs meets all these requirements.  The first release, the EPC21601 laser driver IC, integrates a 40 V, 10 A FET with integrated gate driver and 3.3 V logic level input in a single chip for time-of-flight (ToF) lidar systems used in robotics, surveillance systems, drones, autonomous cars, and vacuum cleaners. This chip offers frequency capability up to 200 MHz in a low inductance, economical, 1 mm x 1.5 mm BGA package.
