Why do we choose digital control power supply？

NXP is a globally renowned semiconductor company, which means that using NXP CNC chips in our power products can help achieve higher efficiency, less loss, smaller size, and better heat dissipation/lifespan performance.

Our NXP digital control chip (Digital Control/Digital Signal Controller) has the following key advantages compared to traditional analog controllers:

1. Higher control accuracy and stronger programmability

Digital control chips allow for flexible configuration of control parameters (such as switching frequency, mode switching, protection threshold, low-power mode, etc.) through software/firmware - rather than relying solely on fixed hardware analog circuits. This way, you have more room for optimization in the product solution, and can better adapt to changes in power, load, and environmental temperature of your product.

2. Higher efficiency+lower standby power consumption

For power products, using such digital control chips can help the overall solution: reduce losses, lower heat generation, improve lifespan, and enhance green and energy-saving performance. These are all competitive advantages that customers value.

3. More comprehensive protection functions and higher system reliability

Digital control allows for the integration of more "programmable protection/monitoring" functions: over temperature protection (OTP), over-current protection (OCP), over-voltage protection (OVP), open-loop protection (OLP), X-capacitor discharge monitoring, low-power mode switching, burst/static mode switching, etc.

The programmable protection threshold and mode switching of digital chips mean that products have stronger adaptability when facing anomalies, load shocks, temperature changes, and aging processes

4. Higher integration of the solution/fewer external components in the system/more flexible design

This means that a single chip can cover PFC+LLC resonance control, driving, boost start, mode switching, and other functions, reducing external components, lowering scheme complexity, and improving reliability.

Most Taiwanese manufacturers only use chips from the Hongguan brand for their power supplies, while we use the globally renowned brand NXP. NXP uses digital control, while Hongguan uses analog control. In our power supply product, we use NXP's digital control chip instead of traditional analog control solutions. This brings:

1. More precise control, able to maintain high efficiency from light loads to high loads;

2. Lower standby power consumption and better energy-saving performance;

3. Stronger protection functions and system reliability;

4. The system requires fewer peripheral components, has a simpler structure, and has fewer fault points;

We have made more investment in design and material selection to ensure that the product is superior in performance, lifespan, and market adaptability.

Compared to traditional solutions that use analog control chips, our solution is more future oriented, reliable, and trustworthy.
