THINKANTECH Launches New 100W GaN Power Supply Solution, Captivating the Power Amplifier Market
THINKANTECH announced the launch of its latest 100W power adapter solution, which has quickly gained significant traction and widespread acclaim within the power amplifier market.
The power supply features an open-frame PCBA design with 3.96mm pitch pin terminals for both input and output, facilitating easy and secure connections. Its sleek, rectangular form factor embodies a minimalist yet robust design. The adapter delivers a stable 100W output at 12V/8.33A and has secured multiple international certifications, including UL, FCC, CE, PSE, VI, EAC, NOM, and KC, ensuring compliance and reliability for global deployment.
By integrating THINKANTECH's flagship Gallium Nitride (GaN) and Silicon Carbide (SiC) components, this power solution enables power amplifiers to achieve exceptional performance characteristics: compact size, superior efficiency, minimal heat generation, a wide operating voltage range, low power loss, and low impedance.
Customers experience tangible improvements in their final products, which are now smaller, lighter, and operate at significantly lower temperatures, mitigating overheating concerns. The power supply's stability ensures consistent amplifier performance even under fluctuating voltage conditions. Furthermore, its high efficiency translates directly into energy savings.
Since its market introduction, the power solution has been met with strong customer approval, driving significant order volume.
Technical Teardown:THINKANTECH 100W GaN Power Supply
A teardown of the adapter reveals its sophisticated internal design.
Architecture and Appearance
The power supply utilizes a high-efficiency PFC + LLC resonant topology, with synchronous rectification on the output stage.
Key components include:
PFC Boost Circuit: One THINKANTECH's X3G6516B5 GaN HEMT.
PFC Rectifier: One THINKANTECH's XD065A0065 SiC Diode.
LLC Half-Bridge: Two THINKANTECH's X3G6516B5 GaN HEMTs.
The module's output specification of 12V at 8.33A is ideally suited for compact, high-power amplifier applications. A view of the PCBA's reverse side shows the layout from left to right: PFC boost switch, PFC rectifier, LLC half-bridge switches, and the synchronous rectifier.
PCBA Dimensions: 81.49mm (L) x 55.84mm (W) x 23.71mm (H).
In-Depth Module Analysis
This section explores how the integration of GaN technology transforms the performance of the power module.
Specifications:
Input: 100-240V~, 50/60Hz, 2A
Output: 12V, 8.33A, 100W
The board layout, from left to right, comprises the input EMI filter circuit, PFC boost inductor, high-voltage filter capacitors, and the LLC transformer. The output stage features vertically arranged solid-state filter capacitors. Both input (3.96mm 3-pin) and output (3.96mm 4-pin) use convenient plug-in terminals for seamless integration into host devices.
Component Analysis
This 100W power module is engineered around the NXP TEA2017AAT for combined PFC and LLC control and the TEA2095 for LLC synchronous rectification. The primary side features one THINKANTECH's X3G6516B5 GaN HEMT for PFC boost and two additional X3G6516B5 GaN HEMTs forming the LLC half-bridge. The PFC rectification is handled by an THINKANTECH's XD065A0065 SiC diode, which effectively reduces reverse recovery losses in Continuous Conduction Mode (CCM).
1. NXP TEA2017AAT Digital LLC+PFC Combo Controller
The NXP TEA2017AAT is a digital, configurable controller for high-efficiency resonant power supplies. It can be configured to operate the PFC in DCM/QR, fixed-frequency CCM, or a multi-mode operation that optimizes efficiency across all conditions. The TEA2017AAT simplifies the design of a complete resonant power supply with a minimal number of external components. Its digital architecture, based on a high-speed configurable hardware state machine, ensures reliable, real-time performance. Housed in a compact narrow-body SO16 package, its proprietary configuration is secured against unauthorized duplication. The controller's low-power LLC mode delivers exceptional efficiency at light loads.
2. THINKANTECH's X3G6516B5 GaN HEMT (PFC Boost Switch)
The PFC boost stage uses the THINKANTECH's X3G6516B5, a 700V (rated, 650V in description) enhancement-mode GaN switch. It features a low on-resistance (Rds(on)) of 150mΩ and supports a continuous current of 13A. Key characteristics include low input capacitance, zero reverse recovery loss, and suitability for high-frequency operation.
3. THINKANTECH's XD065A0065 SiC Diode (PFC Rectifier)
This 650V SiC diode provides a current rating of 6A at 163°C. It exhibits zero reverse recovery current and a positive temperature coefficient, which simplifies parallel operation. Its high-speed switching capability results in low switching losses and reduced thermal management requirements.
4. THINKANTECH's X3G6516B5 GaN HEMT (LLC Half-Bridge Switches)
The LLC half-bridge is composed of two X3G6516B5 GaN switches, identical to the PFC switch. Their superior characteristics are critical for achieving high efficiency and power density in the LLC stage.
