TEA2226AT/1Y Overview
An LLC controller governs a resonant half-bridge topology in which two MOSFET switches drive a series resonant tank (inductor-capacitor-inductor) through a transformer. By modulating the switching frequency, the controller regulates the output while the tank naturally achieves zero-voltage switching (ZVS), dramatically cutting switching losses compared with conventional hard-switched PWM converters. LLC controllers sit at the heart of the power management IC hierarchy, above generic PWM controllers and alongside PFC controllers in complete AC-DC solutions.
Key features of the TEA2226AT include a digital configurable architecture that enables power supply design with a very low component count, integrated gate drivers, and an internal level shifter for the high-side switch. The device contains a high-voltage silicon-on-insulator (SOI) controller stage for direct high-voltage start-up, eliminating the need for an auxiliary low-power startup supply. On-chip circuitry ensures zero-voltage switching under normal operation, and a suite of integrated protections guards the converter against fault conditions.
Architecturally, the TEA2226AT combines digital configurability with the robustness of an SOI high-voltage process. Digital configuration allows the resonant control behavior to be tailored to the application without extensive external analog component tuning, shortening design cycles and improving consistency between units.
Typical applications include notebook and desktop adapter power supplies, server and telecom rectifier stages, and consumer electronics adapters that must meet Energy Star, US Department of Energy (DoE), European Union Ecodesign, and European Code of Conduct efficiency regulations.
Design-wise, verify that the SUPHS floating supply for the high-side driver stays within the 18.2 V to 19.7 V window, and follow the NXP datasheet guidance for bootstrap and protection component selection.

Typical Applications
TEA2226AT/1Y is suitable for 6 applications: AC-DC Adapter Power Supplies, Server and Telecom Power Supplies, Consumer Electronics Adapters, LED Driver Power Supplies, Industrial Power Supplies, USB-PD Fast Charger Power Stages.
AC-DC Adapter Power Supplies
The TEA2226AT/1Y fits high-efficiency AC-DC adapters for notebooks, monitors, and consumer electronics, where Energy Star and DoE efficiency rules mandate low average operating efficiency losses and strict standby power. Its LLC resonant topology achieves zero-voltage switching, reducing switching losses across the wide load range typical of adapter duty cycles, while digital configuration tailors the resonant control to the specific tank design with minimal external components. The high-voltage SOI start-up stage removes the auxiliary low-power startup supply, cutting standby losses and board area. Placed as the half-bridge controller driving the resonant tank through integrated drivers and level shifter, it delivers a compact, regulation-compliant adapter design with high reliability thanks to integrated protections.
Recommended
Server and Telecom Power Supplies
Server PSUs and telecom rectifier front ends demand peak efficiency under continuous load to minimize heat and energy cost, and the TEA2226AT/1Y addresses this directly. NXP states the part enables highly efficient, reliable power supplies meeting European Code of Conduct and DoE guidelines - core requirements in datacenter and telecom procurement. The ZVS ensure circuitry keeps the half-bridge switching loss near zero at typical 50-100% server loads, and the digital configurable architecture allows the regulation loop to be tuned to server tank designs without extensive analog tuning. Integrated protections safeguard against the fault scenarios expected in always-on infrastructure, and the low component count improves long-term field reliability of high-availability power stages.
Recommended
Consumer Electronics Adapters
Set-top boxes, gaming consoles, printers, and smart-home hubs use compact AC-DC adapters where the TEA2226AT/1Y delivers both efficiency compliance and very low component count. According to NXP, no auxiliary low-power supply is required because the integrated SOI high-voltage start-up feeds the controller directly from the rectified mains, simplifying the adapter PCB and improving no-load power figures demanded by EU Ecodesign rules. The digital configurable control lets one controller platform serve multiple adapter power levels, reducing qualification effort across product families. ZVS operation also lowers audible noise and EMI filter burden, valuable in living-room consumer devices where acoustic and electromagnetic emissions are tightly scrutinized.
Recommended
LED Driver Power Supplies
High-power LED luminaires and street-lighting drivers benefit from the TEA2226AT/1Y LLC topology, which provides isolated, regulated output with high efficiency at the constant high load factors typical of lighting duty. NXP highlights that supplies built on this controller meet Energy Star and DoE efficiency regulations - prerequisites for ENERGY STAR certified luminaires in many markets. The ZVS resonant operation reduces switching stress on the primary switches, extending driver lifetime in sealed outdoor fixtures where thermal cycling and component aging dominate reliability. The very low component count and integrated protections allow compact driver form factors suitable for slim luminaire housings while meeting surge and fault protection expectations in lighting installations.
Recommended
Industrial Power Supplies
Industrial control cabinets, PLC power modules, and instrumentation supplies operate from wide mains conditions with high reliability expectations, matching the TEA2226AT/1Y profile. The controller's digital configurable architecture allows the LLC regulation behavior to be adapted to industrial tank designs and hold-up-time requirements, while integrated protections cover overload, fault, and abnormal operating conditions expected in factory environments. NXP positions the TEA2226AT as enabling easy-to-design supplies with very low component count, which shortens industrial design cycles and eases safety isolation layout on the primary side. The SO16 surface-mount package supports automated assembly for industrial volume production, and the 18.2 V to 19.7 V supply window accommodates standard auxiliary winding bias arrangements.
Recommended
USB-PD Fast Charger Power Stages
High-wattage USB-PD GaN and Si chargers increasingly adopt LLC resonant stages for efficiency and power density, and the TEA2226AT/1Y provides the resonant control in such designs. Its digital configurability supports the wide output voltage range characteristic of USB-PD (negotiated 5 V to 48 V rails), where the controller must regulate across large operating point swings while maintaining ZVS; the ZVS ensure circuitry addresses exactly this condition. NXP notes the low component count and easy design flow shorten charger development cycles, important in the fast-moving consumer charger market. Integrated high- and low-side drivers with level shifter allow direct drive of compact half-bridge switch pairs, maximizing power density in wall-cube form factors.

Design Notes
Keep the SUPHS high-side floating supply and the controller VCC within the specified 18.2 V to 19.7 V window under all line and load conditions. Size the bootstrap/auxiliary winding and its rectifier so the rail does not droop below the window at minimum burst-mode load or rise above it during transient events. Because the TEA2226AT integrates high-voltage SOI start-up, no separate startup resistor chain or auxiliary startup supply is needed, which also improves standby power - a key parameter for Energy Star and DoE compliance.
Place the high-side and low-side gate drive loops as compact as possible: the integrated drivers and level shifter mean the SUPHS, bootstrap, and driver ground return paths must be short, wide traces with solid ground planes to limit loop inductance. Keep the resonant tank capacitor and half-bridge switch node away from the controller's analog feedback and protection sensing pins. Follow the NXP datasheet layout recommendations for the SO16 package, and provide adequate copper for the high-voltage creepage and clearance distances from rectified-mains nodes to low-voltage controller pins.
Do not assume the TEA2226AT behaves like a generic analog LLC controller: it is digitally configurable, so protection thresholds, soft-start, and regulation behavior follow the configured profile rather than discrete external component values. Verify configuration settings against the datasheet before layout freeze, and confirm the ZVS ensure circuitry timing with your specific resonant tank - a mistuned tank can lose ZVS at light load, raising switching losses and EMI. Also confirm current RoHS/compliance declarations on the official NXP page, since distributor snippets do not carry them.
