- 适用于lidar的大功率激光二极管高速驱动ecogan™和高速栅极驱动器参考设计
lidar传感器不仅适用于车辆的自动驾驶应用，还适用于工业和基础设施领域的众多应用。lidar传感器需要具备更远的感测距离和高分辨率，不仅要提高激光二极管的特性，还需要以更快的速度和更高的功率驱动激光二极管。rohm拥有905nm脉冲的高功率窄线宽激光二极管产品群（rld90qzwx系列）。另外，rohm还提供包括可高速驱动的下一代gan器件“ecogan™”和用于gan hemt的高速栅极驱动器在内的参考设计，这将非常有助于提高lidar传感器的特性（距离、分辨率）。
- enables high-speed driving of laser diodes - a key device in lidar applications
- includes next-gen ecogan™ devices
- built-in high-speed gate driver for gan hemts (bd2311nvx-c)
- two circuit types: square wave and resonant
-
- logicoa™ solution buck converter (12v input, 5v output, 25w)
logicoa001-evk-001 is a reference design for a buck converter that uses rohm's analog-digital fusion control technology logicoa™, which includes a microcontroller ml62q2035 suitable for logicoa™, a 100v gate driver bd2320efj-la, ldo bd950n1wg-c, bd900n1wg-c, operational amplifier bu7481sg, and shunt resistor ltr100ljzpfsr020. design data, sample software, and an operating system for power supply control are available for this reference design, as well as a reference board. we hope that you will have a chance to experience the analog-digital fusion control logicoa™ and make use of it in your future power supply device development.
reference program
we offer a reference program comprising an os for power control and firmware for buck converter control. additionally, we provide a communication gui that allows communication from a windows pc. please utilize these as design references. reference program and communication gui are available here.
