EPC21603 – 40 V, 10 A eToF Laser Driver IC –PRELIMINARY40 Volt, 10 Amp Peak, High-Frequency, Integrated Laser Driver Description The EPC21603 is a laser driver that is control ed using LVDS logic at high frequencies of up to 100 MHz to modulate VDD GND GND laser driving currents of up to 10 Amps. Full driver integration is achieved using EPC’s proprietary GaN IC technology. Wafer level chip-scale packaging is used resulting in a BGA package that measures only 1.5 mm x 1 mm x 0.68 mm. IN+ IN- D The BGA package has low inductance and lays out very wel with the laser system. 1.5 mm x 1 mm, 0.5 mm pitch Bump side view The EPC21603 uses a 5 V logic supply and is capable of interfacing to digital controllers. It can switch at frequencies exceeding 100 MHz. Features • VLaser operating range up to 30 V • 10 Amp peak current • Switching frequency greater than 100 MHz • Voltage switching time less than 500 ps • 5 V nominal logic power supply • LVDS logic compatible input control • 2 ns minimum input pulse width • 2.9 ns delay time from input to output Functional Block Diagram Applications • Time of flight measurement o Gesture recognition o Gaming o Driver monitoring o Robotic vision o Vacuum cleaners o Industrial safety o Machine vision • ToF module using VCEL laser for camera modules, laptops and smart phones Subject to Change without Notice www.epc-co.com COPYRIGHT 2021 Page 1
