Summary of reference designs
CorEnergy Nenghua
Nenghua 36W gallium nitride adapter solution
The traditional Si adapter scheme works in CCM mode, in addition to the conduction loss and switching loss of the main switching device, there is also the loss of the secondary side reversing the transfer to the primary side, and the junction charge of the Si MOS is relatively large, and the switching speed is slow, resulting in a relatively large switching loss. Therefore, the overall loss of the primary side main switch device is relatively large, and it is necessary to increase a large piece of aluminum heat sink, and increase the manual screwing and other processes, which greatly slows down the production speed and keeps the processing cost high.
The gallium nitride adapter scheme launched by Nenghua adopts QR mode to achieve complete ZVS under low-voltage input conditions, no switching loss, and no loss transferred from secondary side reverse recovery, only conduction loss, so the heat generation is greatly reduced, TO-252 chip package can be used, and SMT process is directly adopted without increasing heat sink to assist heat dissipation, avoiding the labor-intensive processing method of large heat sink and screwing, which greatly improves production efficiency.
DX Nitrogen Silicon Technology
Nitrosilicon Technology's 120W GaN adapter solution
GaN is in full swing in the field of fast charging, but with the continuous update of technology, GaN has gradually begun to develop in multiple dimensions, and now it has intensified in the field of adapters. The low conduction resistance and high efficiency advantages of GaN can further reduce the size of the product, improve energy efficiency, and bring the power density of adapters to a new level.
Recently, the charging head network learned from the official channel of Nitrosilicon Technology that for the field of adapters, Nitrosilicon Technology has launched two GaN adapter solutions of 120/240W to provide customers with more cost-effective adapter solutions.
Nitrogen Silicon Technology's 120W GaN adapter solution, the main control IC uses TEA2017+NCP4318B, with DXC1065S2C/DX65F130.
The average efficiency of the 120W GaN adapter solution is above 92% throughout the load phase, with the highest efficiency reaching 94.50%. In terms of standby power consumption, the 120W GaN adapter solution of Nitrosilicon Technology has a standby power of only 0.139-0.274W for light and medium loads, and only 0.435W for heavy loads
Nitrogen Silicon Technology 240W GaN adapter solution
Nitrogen Silicon Technology's 240W GaN adapter solution, the main control IC adopts TEA2017+NCP4318B, with DXC1065S2C/DX65F080.
The average efficiency of the 240W GaN adapter solution is above 93% in the entire load stage, and the highest full-load efficiency is 94.81%, which is at the leading level in the industry. The 240W GaN adapter solution of Nitrogen Silicon Technology has a standby power of only 0.16-0.261W for light and medium loads, and only 0.441W for heavy loads, which can well meet the relevant requirements in terms of energy efficiency.
Innoscience 英诺赛科
Innoscience's 60W GaN LED driver solution
Innoscience's 60W LED driver reference design is a single-stage, high-PF flyback design with primary-side feedback, no optocoupler, output current sense resistor, and constant current control circuitry. The constant voltage control is completed in the primary stage, and the circuit is simplified, simplifying the design and improving the conversion efficiency.
This 60W LED driver is housed with Innoscience INN700TK350B GaN switch in a TO252 package and is rated at 700V and 800V transient for mains applications. The power supply adopts the XP3358 high PF flyback controller, and the output adopts diode rectification and electrolytic capacitor filtering.
After the introduction of gallium nitride into the LED power supply, the high conversion efficiency advantage of low switching loss can reduce the heat dissipation demand of the power supply, reduce the volume of the power supply, and also reduce the overall cost of the power supply, which is energy-saving and low-carbon, and more environmentally friendly.
Innoscience 300W GaN Adapter Solution
Compared with the conventional Si MOS adapter, it is adopted at the same 300W output power
InnoGaN's solution can be reduced by 30% and the power density can be increased by 8W/in^3.
Innoscience's 2KW PSU Titanium Solution
The solution is perfectly aligned with the 80 Plus Titanium efficiency with a peak efficiency of 96.5%, which is key to reducing power and increasing efficiency in targeted applications such as data center power supplies, communications power supplies, and LED lighting power supplies.
Innoscience's 2KW PSU solution features a totem-pole bridgeless PFC+LLC structure with an AC-DC bridgeless totem-pole PFC at the front end and a DC-DC isolated full-bridge LLC converter at the back.
Innoscience's 2KW 12V PSU solution can not only reduce power consumption and increase efficiency for data center links, but also reflect the advantages of small size and high efficiency in applications such as communication power supply and LED lighting.
