40 Volt EPC21603 eToF Laser Driver IC for Augmented Reality Based Applications
Efficient Power Conversions (EPC) has introduced the EPC21603, a laser driver with a 40V, 10A FET integrated with a gate driver and low-voltage differential signaling (LVDS) logic level input in a single chip. Controlled by using the LVDS logic, the new laser driver is capable of very high frequencies exceeding 100MHz and super short pulses (< 2 ns) to modulate laser driving currents up to 10 A.
The new single-chip driver plus eGaN FET uses EPC’s proprietary GaN IC technology in a chip-scale BGA form factor that measures only 1.5 mm x 1.0 mm. The LVDS logic control allows the eToF laser driver IC to be controlled from an FPGA for applications where noise immunity is critical, such as augmented reality.
The integrated device in single-chip ensures the easier design, easier layout, easier assembly, increased efficiency, reduced cost and saves space on the PCB. The new family of products will provide faster adoption and increased ubiquity of ToF solutions in various applications such as time-of-flight lidar systems used in robotics, drones, augmented reality, and gaming applications.
The EPC9156 development board features EPC21603 eToF laser driver IC and is primarily intended to drive laser diodes with short, high current pulses. The EPC21603 EToF laser drive IC is priced at less than $1.00 at 500 ku.
