Rohm

The range of uses for LiDAR sensors is expanding to include not only autonomous driving, but also applications in the industrial and infrastructure fields. Improvements to LiDAR sensors are producing longer range and higher resolution.

In addition to improving the characteristics of the laser diode, it is necessary to drive the laser diode at higher speeds and power. The ROHM RLD90QZWx series is a line of 905 nm, high-power, narrow emission-width laser diodes.

The REFLD002-1 reference design includes the BD2311NVX-LB gate driver to drive the RLD90QZWx laser diode. The high speed of the BD2311NVX-LB contributes to improved LiDAR sensor range and resolution.

STMicroelectronics

The EVL012LED is an LED driver board. The architecture is based on a two-stage approach: a front-end PFC pre-regulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that integrates the controllers of both sections in a single device. 

The main features of this design are high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced component count. 

The board also has a full set of protection features including output overload, short-circuit, and over-voltage, all of which can be easily defined as latched or auto-restart by changing a value in the non-volatile memory of the controller.

Power Integrations

The RDK-877 reference design describes an isolated flyback converter which provides a nominal output voltage of 12 V at 0.5 A load from a wide input-voltage range of 90 V to 305@nbsp;V ac, as well as an isolated zero-crossing detection signal. 

This power supply uses the LNK3306D from the LinkSwitch-TNZ family of ICs. The kit contains the complete power-supply specifications, bill-of-materials, transformer construction, circuit schematic and PCB layout, along with performance data and electrical waveforms.

 

Power Integrations

The RDK-866 reference design describes a non-isolated buck converter power supply with an input-line zero-crossing detection output signal. The nominal output is 5 V/500 mA across the input range of 90 V to 300 V ac. 

The system is powered by the LinkSwitch-TNZ IC controller. The LinkSwitch-TNZ family of ICs combines power conversion with lossless generation of an ac zero-crossing signal used typically for system clock and timing functions. The device incorporates a 725 V power MOSFET, oscillator, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry in a monolithic IC. 

Designs using the highly integrated LinkSwitch-TNZ ICs are more flexible than discrete implementations, reducing component count by 40% or more. The key design goal is low cost, low audible noise and compact form factor for use in wireless and relay power supplies.

Infineon

The OPTIGA™ Trust M IoT Security Development Kit is the easiest way to develop and evaluate end-to-end security use cases for IoT devices. The kit enables designers to build prototypes of security applications and build full-featured IoT applications. The board includes:

  • OPTIGA Trust M security solution
  • PSoC™ 62, an Arm® Cortex®-M4/Cortex-M0+-based microcontroller
  • AIROC™ CYW43012, a low-power system-on-chip which supports dual-band 2.4 GHz and 5.0 GHz Wi-Fi®/Bluetooth® 5.0 networking

This development board is supplied with two ready-to-use security use cases:

  • Secured communication with AWS over MQTT using cryptography support from the OPTIGA Trust M
  • Secure, zero-touch cloud provisioning using a CIRRENT™ Cloud ID and the pre-provisioned X.509 certificate delivered with the OPTIGA Trust M

The kit is supported by the ModusToolbox™ design tool. The OPTIGA Trust M host library is available as open source code.

 

Melexis

The EVB90394 evaluation board from Melexis provides an easy way to connect the MLX90394 Triaxis® magnetometer IC to a microcontroller or measurement device.

The MLX90394 IC is mounted on the EVB90394 together with a 100 nF decoupling capacitor and three pull-up resistors. Two precision headers are available for compatibility with the Melexis Triaxis DVKMagnetic board, which is supplied separately. 

The DVKMagnetic kit provides an easy way to connect the EVB90394 to magnetic devices such as a rotary knob, linear slider and joystick, which are included in the kit along with an off-axis magnet holder. The interface also provides pin-outs for an external LCD display and Arduino/Mbed boards, which are not included.
