Linear LED Driver

Heat dispersion is connected to an external power shunt resistor, and the power previously consumed inside the linear IC is awakened by an external resistor to reduce the temperature rise of the IC.

     

Without MCU control, the chip has its own fade in and out effect, the fade in and out time can be set by external resistance, IS32LT3144 ICTRL can support analog dimming, with NTC can be used for LED overtemperature drop current.

Switching LED Driver

As for the function of spread spectrum, it is the function of alleviating the noise concentrated in a specific switching frequency by deliberately modulating the switching frequency. Spread spectrum can extend the total electromagnetic emission energy to a larger range and significantly reduce the average energy of electromagnetic interference. Under spread spectrum conditions, electromagnetic interference testing can use a smaller size and lower cost filter circuit; With the popularization of vehicle electrification and automatic driving, the EMC registration requirements for on-board equipment are becoming more and more stringent. By increasing the spread spectrum function, as long as a small number of peripheral filter parts can easily pass the CISPR25/Class5 EMC standard, analog dimmer ICTRL is used for over-temperature and current reduction protection, and NTC thermistor is connected. As the LED current temperature rises, the thermistor resistance value decreases, the VICTRL voltage decreases, and the output current can be derated according to the voltage of the ICTRL pin.

LED Lighting

For lighting devices with batteries, due to size and total cost considerations, Sinomin needs to provide an additional adapter with a maximum power of 24W or less. We successfully persuaded the R&D department to use type-C interface and add PD sick controller ap33771/2 instead of the original power interface, which can reduce the charging time of the end-user's existing higher power PD adapter. It reduces the total cost and pollution of the earth by e-waste.

Car Backlight LED

The side design has no lead frame, thus obtaining excellent brightness performance, also because the side has no lead frame, after adding white reflective material on it, the Angle can reach 180·, the light display around except the top side, this is because there is a white silicone reflector on the top of the LED package, it will display a red light from the top, but because of the white silicone mirror, You will gain a greater perspective.

Ambient Light Driver

The high frequency is to eliminate the resistance noise, but the ghosting will increase. The low frequency is conducive to eliminating ghost, but the phenomenon of high frequency noise of large capacity ceramic capacitors. Customers can adjust the PWM frequency according to the actual situation of the board, choose the optimal setting, multi-chip series method as long as the MCU frequency is fast enough, you can cascade multiple IS32FL3726A, chip communication rate can support up to 30MHz.

AMD EPYC Genoa Server (Server)

AMD will reduce the cache size to fit more cores, but beyond that, this will be AMD's high-kernel-count solution, with up to 128 cores per slot. Genoa-X will break the L3 cache barrier of 1GB/socket. Using standard Genoa, we can get up to 384MB of L3 cache per socket or 768MB of L3 cache per 2P server. With Milan-X, we have 64 cores and up to 768MB of L3 cache per slot, and Genoa-X will target applications, such as those in the HPC space, where adding 3D V-cache increases data locality and thus reduces power waste on moving data.

ASPEED Cupola360 (Panoramic Camera)

Cupola 360 developed by ASPEED is a software and hardware integrated solution. In addition to chip processing, ASPEED also brings a mature enough APP that supports both iOS and Android platforms. It supports H.264/HEVC video recording. It can record 4K/30fps video screen, shoot 4K static images, and provide three functions of photography, video and live broadcast in the shooting interface. Live broadcast does not require a third-party plug-in, as long as there is a corresponding code to push the stream. At present, the APP only supports manual adjustment of exposure brightness.
