Power supplies (PSUs) are the core of all electronic products, providing them with primary power. With the trend towards energy conservation and carbon reduction, international regulations are imposing increasingly stringent power consumption requirements on products, driving the industry towards low power consumption, high efficiency, and high reliability.
From low-voltage handheld device chargers to high-power uninterruptible power systems (UPS) and server power supplies, whether it's AC-DC conversion or DC-DC Brick architecture, the design requirements for components are extremely stringent.
Golfee offers a complete range of discrete components, an indispensable key component in power supply design solutions. Our product portfolio includes:
-
SMT bridge rectifier
-
MOSFETs with low FOM (factor of quality) contribute to increased power density.
-
ESD protection components and TVS (surge suppression components): effectively protect the main power management IC and reduce damage caused by external instantaneous high voltage.
Golfee is committed to providing high-quality components to help customers create high-efficiency power supply products that meet stringent standards.

Power supplies and chargers Solutions
Power supplies are the energy core of electronic devices, providing stable power through transformers and chargers. This not only improves the performance of the devices but also helps save energy consumption to meet international energy standards such as 80 Plus®, ErP Lot 6, and Energy Star.
As people carry more electronic devices, the market demand for transformers and chargers is shifting towards thinner, lighter, more efficient, and faster charging speeds.
The widespread adoption of electronic products has necessitated a key development in fast charging and PD technology. This has led to the need for solutions that increase charging convenience, shorten charging time, and maintain high-efficiency output. Fast chargers and **PD chargers** on the market represent solutions to this trend.
PD Chargers enable fast charging via USB ports or USB Type-C interfaces, while also serving as a stable power source for electronic devices. They are compatible with a wide voltage range, covering electronic products from 5V to 28V.
Golfee fully understands its customers' needs for different power density designs and their market promotion considerations.
From the MOSFETs in the HV/LV power switch to the ESD protection components in the USB Type-C interface,Golfee offers a diverse product portfolio and optimal solutions to help customers develop high-efficiency power products that meet market trends.
Server power solutions
With the surge in demand for cloud computing, Internet of Things (IoT) devices, and smart transportation systems, the scale, density, and number of global data centers are growing at an alarming rate. This has led to persistently high electricity demand and carbon emissions, making it crucial to improve the power conversion efficiency at each stage of power supplies to reduce carbon emissions.
To ensure uninterrupted operation of large data centers, their server power systems must have higher output power, power density, and energy efficiency. Currently, 12V DC-DC conversion is the most common server power system architecture, while 48V DC-DC conversion is also widely used.
Golfee offered a range of optimal solutions for this purpose, including:
MOSFET: Used for high-efficiency power conversion.
FRED (Fast Recovery Diode): A new fast recovery diode technology that further improves efficiency.
TVS components: provide voltage suppression over a wide electrical range to protect power management ICs.
These components can effectively help customers design more energy-efficient and reliable server power solutions.
DC-DC Module Power Supply Solutions
DC-DC Brick power converters are characterized by their small size and high efficiency, effectively meeting engineers' stringent requirements for space utilization and time-to-market.
These DC-DC power converters can be directly soldered onto printed circuit boards (PCBs), and their size and power must comply with the standards of the Distributed Power Open Systems Alliance (DOSA).
Due to their compact size and high efficiency, DC-DC power bricks greatly enhance engineers' design flexibility.
Golfee offers a variety of SGT MOSFET solutions to meet different size and power design requirements, helping customers develop high-performance DC-DC Brick products.
Uninterruptible Power Supply (UPS) Solutions
Uninterruptible power supply (UPS) systems primarily use 12V or 24V power supply and can be divided into three main categories based on their operating method:
Offline/Standby UPS
Line-Interactive UPS
Online/Double-Conversion UPS
Golfee provides complete electronic component solutions for various UPS systems, ensuring system stability and efficiency:
Primary Side: Provides components such as HV MOSFET (High Voltage Metal Oxide Field Effect Transistor) and FRED (Fast Recovery Diode).
Secondary Side: Offers Schottky diodes, MV MOSFETs, Bridge rectifiers, and FREDs, all of which offer advantages such as high voltage withstand capability, high efficiency, and low power consumption.
With these high-quality components, Sangchan can effectively assist customers in designing more reliable and energy-efficient UPS products.
