Heavy new product | Nanxin Technology launches industrial grade SSR controllers for electric tools and TVMonitor applications

As a pioneer in the localization of PD fast charging, Nanxin Technology has launched a complete set of solutions for the USB-PD adapter market, including secondary feedback (SSR) controllers suitable for a wide output voltage range, ultra fast turn off secondary synchronous rectification (SR) controllers, and protocol chips integrated with CC/CV control loops. We are committed to creating high power density, high safety, and high reliability fast charging products for customers, meeting various application scenarios.

 

Recently, Nanxin Technology has launched an industrial grade SSR series control chip - SC303x/SC304x, mainly targeting industrial and TV/Monitor markets, providing users with more reliable and cost-effective solutions.

 

The parameter selection is as follows:

 

Product Introduction

SC303x provides adaptive switching frequency reversal, achieving higher efficiency throughout the entire load range. When overloaded or fully loaded, its operating frequency can reach 65kHz. When the load decreases, its working mode can smoothly transition to green mode, and the voltage valley is opened to achieve high efficiency. When unloaded, the IC will operate in Burst mode to reduce power consumption. In addition, the implementation of Peak Load Mode (PLM) to minimize the design of transformer size requires high transient load capacity. It has functions such as low startup current, fast startup speed, and low standby power consumption. Burst mode, extremely low operating current, significantly reduces standby power consumption, and meets efficiency requirements.

 

SC303x provides comprehensive protection to prevent circuit damage in abnormal situations. In addition, the characteristics of frequency jitter and intelligent driving function can greatly reduce noise and improve EMI performance.

 

 

The SC303x series can operate in CCM/QR/DCM mode, and its high-precision busbar voltage overvoltage protection (Line OVP) can protect the power system from damage in more harsh grid environments, with overvoltage protection accuracy reaching± 5%; Support peak power output, allowing the system to output more than twice the rated power in a short period of time, meeting the instantaneous power demand of the load without increasing volume and cost.

 

The SC303x series can be used for power tools, laptop adapters, printers, speakers, small household appliances, and more.

 

The current new TV/Monitor motherboards tend to integrate the power supply, LED backlight driver, and signal processing communication motherboards on the same board to improve performance and reduce assembly costs; The integration and complexity of the board have increased, posing higher requirements for the reliability and safety of the components on the board, especially the power supply part.

 

  SC304x series

 

The SC304x series is suitable for TV/Monitor applications, and independent bus voltage detection can achieve fast shutdown of AC power failure; In addition, the IC has more than 10 protection functions: input bus undervoltage protection, two-stage output overcurrent protection, output short-circuit protection, output overvoltage protection, secondary diode short-circuit protection, secondary winding short-circuit protection, sampling resistor short-circuit protection, MOS transistor cycle by cycle current limiting protection, VDD overvoltage and undervoltage protection, over temperature protection, etc;

SC3040 has an independent BNO pin, which can quickly identify bus voltage information and achieve fast bus power-off protection; Internally integrated with two levels of high-precision OCP protection function, it can easily pass new safety regulations testing, with higher safety and reliability. The jitter characteristics in full working mode enable the system to have good EMI performance under different operating conditions.

 

SC3040 DEMO (For TV Application)

 

SC3041 has independent OTP pins and precise over temperature protection is achieved through external NTC resistors; Switching between DCM/CCM working modes allows the system to have extremely low noise; In addition, SC3041 can be used with a secondary CC/CV controller to achieve zero voltage output applications.

Summary

 

The industrial grade SSR series control chips recently launched by Nanxin Technology provide users with more reliable and cost-effective solutions, which can be widely used in industrial, TV/Monitor and other markets, bringing customers better choices.
