TEA6017AT/1 Overview
A PFC (power factor correction) controller shapes the input current of an AC-DC power supply so that it follows the input voltage waveform, minimizing harmonic distortion and meeting regulatory requirements such as IEC harmonic limits. In the broader power-management hierarchy, it sits within the class of power supply control ICs and power controllers. The TEA6017AT/1 combines this PFC function with an LLC resonant converter controller, the topology of choice for high-efficiency, low-EMI isolated DC-DC stages in modern AC-DC supplies.
Key features include PFC operability in DCM/QR, CCM fixed-frequency, or multimode operation, allowing designers to optimize efficiency across the entire load range. The digital architecture is based on a high-speed configurable hardware state machine, delivering very reliable real-time performance without firmware. Complete resonant power supply functionality is achieved with a very low external component count, reducing BOM cost and board area.
Technically, the device is the industrial-market equivalent of the TEA2017AAT with improved driver performance, improved ESD performance, and enhanced reliability, per NXP product information. The hardware state machine implements protection and control timing deterministically, which simplifies compliance-focused designs. Applications include notebook adapters, USB-PD fast chargers, TV power supplies, and industrial AC-DC systems where high efficiency and low standby power are mandatory.
A key design consideration is configuring the PFC mode (DCM/QR, CCM, or multimode) to match the target power level and efficiency curve; multimode operation yields the best light-load efficiency. Ensure adequate creepage and gate-drive layout discipline around the LLC and PFC driver outputs.

Typical Applications
TEA6017AT/1 is suitable for 6 applications: USB-PD Fast Chargers and Adapters, Television and Monitor Power Supplies, Industrial AC-DC Power Supplies, Notebook and Gaming Laptop Adapters, Server and Telecom Front-End Supplies, LED Lighting Drivers with PFC Requirements.
USB-PD Fast Chargers and Adapters
The TEA6017AT/1 fits USB-PD fast chargers because its LLC stage delivers soft-switched, high-efficiency isolated conversion while the multimode PFC optimizes input-current shaping across light and full load, a requirement of CoC Tier 2 and DoE Level VI efficiency rules. In a typical adapter, the PFC boost stage operates in DCM/QR at low load and CCM at high load, while the LLC regulates the secondary rail feeding a USB-PD controller. The single SO16 package replaces two control ICs, shrinking board area inside compact charger enclosures. The 50 kHz to 200 kHz range allows small transformers, and the hardware state machine provides deterministic protection without firmware development effort.
Recommended
Television and Monitor Power Supplies
TV and large-monitor power supplies require high efficiency, low standby power, and low EMI - all strengths of the TEA6017AT/1. The LLC resonant stage minimizes switching losses and radiated emissions, easing EMI filter design in the tight enclosure of a flat-panel display. The multimode PFC keeps power factor high from standby through full brightness, and the DCM/QR mode preserves light-load efficiency when the set is idle. The very low external component count enabled by the combo controller reduces BOM cost, which is critical in the price-sensitive TV market. The SO16 package supports standard SMT assembly on high-volume production lines.
Recommended
Industrial AC-DC Power Supplies
The TEA6017AT is explicitly positioned by NXP as the industrial-market equivalent of the TEA2017AAT with improved driver performance, improved ESD performance, and enhanced reliability - exactly the attributes industrial 24V and 48V AC-DC supplies need. Factory automation and DIN-rail supplies face surge events, wide temperature, and long duty cycles; the enhanced ESD and driver robustness improve field survival rates. The digital hardware state machine delivers deterministic protection timing, which simplifies reliability analysis and safety documentation. The 50 kHz to 200 kHz operating range allows designers to balance magnetics size against efficiency targets in fanless industrial enclosures where every watt of loss matters thermally.
Recommended
Notebook and Gaming Laptop Adapters
High-wattage notebook adapters (90 W to 240 W) benefit directly from the TEA6017AT/1 combo architecture. The LLC stage achieves the peak-efficiency plateau that keeps adapters within regulatory average-efficiency limits, while CCM PFC mode handles the high input currents at 240 W. The hardware state machine implements burst mode and protection deterministically, supporting the low standby-power targets required for Energy Star compliance. Because the whole control function fits in one SO16 package, adapter PCBs remain small enough for wall-plug form factors. Improved ESD performance adds margin during handling and surge events typical of travel adapters used worldwide on uncertain mains networks.
Recommended
Server and Telecom Front-End Supplies
In compact server and telecom AC-DC front ends, the TEA6017AT/1 controls both the PFC pre-regulator and the LLC DC-DC stage, delivering the high efficiency demanded by 80 PLUS-class designs. The multimode PFC keeps power factor above 0.95 across the load profile seen in real server duty cycles, and the LLC soft switching reduces switching losses at the 100 kHz-plus end of the 50 kHz to 200 kHz range, allowing power density gains. Deterministic hardware-state-machine protection (no firmware) suits telecom designs that require predictable fault behavior. The very low component count of the combo solution shortens design cycles for platform power iterations.
Recommended
LED Lighting Drivers with PFC Requirements
High-power LED drivers for street lighting and industrial luminaires must meet power factor and harmonic limits, making the TEA6017AT/1 multimode PFC a strong fit. The LLC output stage provides flicker-free, regulated current to the LED string with soft switching that keeps electrolytic-capacitor stress and audible noise low, extending driver lifetime. DCM/QR light-load operation preserves efficiency during dimming, while CCM supports full-output operation. The enhanced ESD and reliability of the industrial-grade TEA6017AT suit outdoor luminaires exposed to surge and temperature cycling. The SO16 package and low component count fit compact IP-rated driver housings with limited board area.

- Firmware-free digital control (vs TEA2017AAT)
Design Notes
Select the PFC operating mode deliberately. DCM/QR gives the best light-load efficiency and simple magnetics, CCM fixed frequency suits continuous high-power operation with lower RMS currents, and multimode combines both for adaptive efficiency. Configuring the wrong mode for the target power level causes efficiency dips and possible instability at mode transitions. Use the NXP TEA6017DK1005 development kit to validate configuration before committing to a PCB spin.
Keep the gate-drive loops of the PFC switch and LLC half-bridge as short and tight as possible; the TEA6017AT has improved driver performance over the TEA2017AAT, so gate currents can be higher and loop inductance matters more. Star-ground the controller ground reference away from power return paths, and place the VCC decoupling capacitor directly at the supply pin. The low-profile narrow-body SO16 requires standard solder-mask-defined pads per the NXP datasheet footprint (SOT109-1 style SO16).
The LLC soft switching of the TEA6017AT/1 inherently reduces high-frequency harmonics versus hard-switched flybacks, but the PFC boost diode reverse recovery remains a dominant EMI source in CCM. Use a SiC or fast-recovery boost diode and snub it appropriately. Because the part is specified for improved ESD robustness versus the TEA2017AAT, industrial surge pre-compliance testing (classical ring-wave and surge tests) should still be performed on the complete adapter front end.
Estimated: size the PFC boost inductor and LLC resonant tank so the operating point stays within the 50 kHz to 200 kHz range at both minimum and maximum load; exceeding the frequency window pushes the controller outside its specified control range. Verify the controller VCC is sourced from an auxiliary winding that remains valid during burst and standby operation, a common failure mode in LLC supplies using combo controllers.
