The NCD57252 evaluation driver board enables evaluation of the NCD57252, a high-current gate driver which can directly drive two independent IGBTs in any configuration. The driver provides 5 kVrmss of internal galvanic isolation from input to each output and functional isolation between the two output channels.Â
This demonstration board uses the AL17052, a buck converter IC operating from a universal mains input voltage, to build a cost-effective solution for high-voltage buck converter applications. The AL17052 integrates a 700V MOSFET and can work with a single-winding inductor and very few external components to provide an accurate constant-voltage output and good dynamic performance.
The STEVAL-DIGAFEV1 evaluation board from STMicroelectronics enables designers to evaluate the performance of the TSC1641, a 16-bit, high-precision current and power monitor which has a MIPI I3C/I2C interface.
The EVALSTGAP2SICS half-bridge board from STMicroelectronics enables evaluation of the STGAP2SICS, an isolated single-channel gate driver for silicon carbide (SiC) MOSFETs. The STGAP2SiCS produces an output drive current of up to 4 A, and offers galvanic isolation of 6 kV.Â
In the EVALSTGAP2SiCS board, the STGAP2SiCS drives a half-bridge power stage with a voltage rating of up to 1,200 V. The components are easy to access on the board and to modify. Â
The board supports negative gate driving. Onboard isolated dc-dc converters supply the high- and low-side gate drivers, with maximum isolation of 5.2 kV.Â
The configuration of the drive voltage can be easily selected from the following options:
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.
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.Â
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.
