Zhuhai Chengfeng Electronic Technology Co., Ltd. was established in 2015 and is headquartered in Zhuhai, a core city on the west bank of the Pearl River Estuary in the Greater Bay Area. The company has established branches and offices in Changsha, Suzhou, Hefei, Shanghai, Beijing, Shenzhen, Chengdu, Wuhan, Thailand, Singapore and other places at home and abroad. It focuses on the research and development, production and sales of semiconductor optical inspection equipment, has completely independent intellectual property rights, self-developed multiple sets of optical microscopy imaging technology, and has mastered and accumulated many years of core graphics detection algorithms. It has launched multiple mass-produced models in the fields of wafer manufacturing and mask manufacturing, including CFW920 and CFW820 series for wafer front-end process control; CFY210 and CFY401 series for mask manufacturing front-end process control; and CF910 six-sided inspection series for back-end process defect detection. It helps the semiconductor industry in process monitoring​

Looks like majority of the analog technology for New energy vehicle charging station is foreign.

These are all old technology, there's no excuse for not able to be self sufficient on this.

China have a lot of room to improve on this. Many industrial products still using tons of US analog chips.

1)The isolation amplifier is from Broadcom, model ACPL-C790, and is used for input current sensing isolation.

2)ON Semiconductor MC33274A 4-op amp is used for current signal amplification.

3)Three voltage regulator chips are used to power the isolation amplifier. The voltage regulator chip comes from STMicroelectronics, model LD1117S50TR, with an input voltage of 15V, an output voltage of 5V, an output current of 800mA, and is packaged in SOT-223.

4)The auxiliary power supply main control chip comes from STMicroelectronics, model UC2845B, which is a high-performance current mode controller in SO8 package.

5)The driver chip comes from Microchip Technology, model MIC4428, which is a dual-channel low-side driver with an output current of 1.5A. It uses a SOIC-8 package and is used to drive the auxiliary power transformer.

6)Close-up of STMicroelectronics' LD1117S50TR voltage regulator chip.

7)ON Semiconductor MC33274A 4 op amp for voltage sampling

8)The PFC (Power Factor Correction)controller comes from Texas Instruments, model TMS320F2808PZA. The chip integrates a C2000 32-bit MCU with a main frequency of 100MHz, built-in 128KB FLASH, supports linkage calculations, has fast interrupt response and processing, and uses LQFP100 packaging.

9) On Semi , Close-up of the 1.8V voltage regulator chip that powers the controller core.

10)ON Semiconductor MC33274A op amp is used for signal acquisition and amplification

11)STMicroelectronics LM239 quad voltage comparator is used for signal processing.

12)Close-up of the ON Semiconductor LM293 dual voltage comparator, which comes in a SOIC8 package and has five in total.

13)The step-down chip comes from Texas Instruments, model TPS5410, supports 36V input voltage, output current of 1A, internally integrated switching tube, and uses SOIC-8 package.

Isn't 台达 a Taiwan company?

Correct me if I am wrong but I think Delta Electronics is from Taiwan province. So their engineers are probably more bias to use US made components

Maybe
But I check majority of products of china main analog chips suppliers for this type of current and voltage control, they seem to be lacking.

Sgmicro, crmicro, silan, 3peak, analogix, fudan microelectronics,

Yet it's astonishing I hear stuff from the media that the F-35 is said to use Chinese chips. True or not I don't know.

Are these foreign branded but made in Chinese plants?
