TEA2017ABT/2 Overview
A combo controller is a power management IC that merges two control functions on a single die: the power factor correction (PFC) stage, which shapes the AC input current to achieve near-unity power factor, and the LLC resonant converter stage, which provides isolated, high-efficiency DC conversion via a resonant tank. Within the power supply controller hierarchy, the TEA2017ABT belongs to the AC-DC controller family, sitting above discrete PWM controllers and below full digital power supervisory systems. Combo integration reduces board area, simplifies inter-controller handshake logic, and lowers the total component count of the complete resonant power supply.
Key features include a digital architecture based on a high-speed configurable hardware state machine, which ensures very reliable real-time control performance without the latency or software-dependency of a microcontroller-based design. The PFC stage supports DCM (discontinuous conduction mode) and QR (quasi-resonant) operation only, while the LLC stage is identical to that of the TEA2017AAT variant. During power supply development, many operation and protection settings of both the LLC and PFC controllers are digitally configurable, giving designers flexibility typically reserved for digital power platforms.
Technically, the state-machine-based digital architecture executes cycle-by-cycle control decisions deterministically, supporting valley switching, adaptive dead time, and multi-mode protection handling. Because the LLC engine and the PFC engine are coordinated on-chip, burst-mode operation and shutdown sequencing can be tightly coupled, improving light-load efficiency.
Typical applications include AC-DC adapters for notebooks and high-power chargers, open-frame and enclosed industrial power supplies, and LED lighting drivers where high efficiency, low standby power, and a low component count are required.
When designing with the TEA2017ABT, note that the PFC operates only in DCM/QR mode: for applications demanding continuous conduction mode PFC at higher power levels, evaluate the TEA2017AAT variant instead.

Typical Applications
TEA2017ABT/2 is suitable for 6 applications: AC-DC Power Adapters, Open-Frame Industrial Power Supplies, LED Lighting Drivers, High-Density Chargers and USB-PD Bricks, Set-Top Box and TV Power Boards, Networking and Telecom Auxiliary Power.
AC-DC Power Adapters
High-power notebook and universal AC-DC adapters benefit directly from the TEA2017ABT/2 combo architecture. The DCM/QR PFC shapes input current for high power factor while avoiding the boost-diode reverse-recovery losses of continuous-conduction designs, and the LLC stage delivers efficient isolated conversion with zero-voltage switching across the load range. Because both controllers share one die, adaptive burst-mode handshaking between PFC and LLC reduces standby power, a key regulatory metric for external adapters. Digitally configurable protection (set during development per NXP) lets adapter makers tune OCP/OVP thresholds without changing hardware. The low component count stated by NXP shrinks BOM cost and board area in puck- and brick-format adapters.
Recommended
Open-Frame Industrial Power Supplies
Industrial open-frame supplies in the tens-to-hundreds of watts class use the TEA2017ABT/2 to meet efficiency and standby regulations while minimizing design iterations. The high-speed configurable hardware state machine gives deterministic cycle-by-cycle control, which simplifies compensation across wide AC input ranges typical of industrial sites. NXP notes the device enables a complete resonant power supply with a very low component count - valuable where conformal coating and small PCBs reduce cost. The -40C to +150C (TJ) rating per distributor data supports harsh factory-floor ambients. Engineers configure protection and operating parameters digitally during development, avoiding resistor-tree tuning and enabling platform reuse across power variants of the same frame.
Recommended
LED Lighting Drivers
High-bay, street, and industrial LED drivers require high power factor, low flicker, and high efficiency - all natural fits for a DCM/QR PFC plus LLC combo. The TEA2017ABT/2's quasi-resonant PFC reduces switching losses at the partial loads where LED drivers spend most of their lifetime, while the LLC stage maintains efficiency over wide output ranges as LED strings age or dim. Deterministic state-machine control avoids the firmware-approval overhead (e.g., functional-safety review of code) associated with MCU-based digital power in lighting certification. The narrow-body SO16 keeps controller footprint small on circular or linear driver boards. Digitally configurable protection simplifies derivative designs across wattage families sharing one PCB layout.

High-Density Chargers and USB-PD Bricks
Gallium-nitride-era chargers still need a robust, low-standby control platform for the PFC and resonant stages. The TEA2017ABT/2 integrates both controllers, so designers achieve the two-stage (PFC + LLC) topology demanded for high power factor in >65 W chargers without a second controller IC. Burst-mode coordination between stages on a single die lowers no-load input power, helping meet CoC Tier-2 / DoE Level VI style standby targets. The configurable digital architecture allows fast prototyping of frequency and protection settings during development, shortening time to market for multiple wattage derivatives. The narrow SO16 fits the tight controller real estate available inside compact brick housings.

Set-Top Box and TV Power Boards
Consumer AV equipment demands low standby power, low EMI, and high efficiency from a compact single power board. The TEA2017ABT/2 serves the main supply of set-top boxes and LCD/LED televisions: the QR PFC switches at valley points to soften EMI signatures, easing filter design against CISPR-class limits, while the LLC stage provides well-regulated low-ripple rails for panel backlight and main SoC supplies. On-chip coordination of burst mode between PFC and LLC reduces light-load power draw during network-standby states. Because operation and protection settings are digitally configurable, one PCB platform can span regional wattage variants, an approach NXP explicitly enables with its very-low-component-count combo design.
Recommended
Networking and Telecom Auxiliary Power
Routers, switches, and small telecom hardware use compact AC-DC front ends where efficiency regulations and thermal constraints overlap. The TEA2017ABT/2 supplies the main rails: the DCM/QR PFC handles universal AC input without CCM boost-diode stress, and the LLC stage provides tight regulation feeding downstream DC-DC points of load. The digital state machine's deterministic behavior aids margining and protection consistency across production units. Junction rating to +150C (TJ) per distributor data supports confined enclosures with limited airflow. NXP's configurable protection lets designers set asymmetric fault responses for telecom brown-out profiles during development, and the low component count eases conformance re-qualification across product families sharing the same power platform.

Design Notes
The TEA2017ABT PFC supports DCM/QR operation only. Confirm during architecture definition that your power level and inductor design work in discontinuous/quasi-resonant conduction; above roughly the range where CCM PFC becomes advantageous, select the TEA2017AAT multimode variant instead. Both parts share the identical LLC stage, so resonant tank design carries over unchanged if you migrate between the two versions.
Per the NXP datasheet, many operation and protection settings of the LLC and PFC controllers are digitally configurable during development. Document your final configuration set and lock it into production documentation - designs that rely on uncommitted configuration values risk inconsistent behavior across builds. Also verify that your gate-drive layout keeps the LLC and PFC driver return paths separated to prevent cross-stage ground bounce.
Use the SO16 narrow-body footprint with short, direct traces from the driver outputs to the PFC and LLC MOSFET gates, and keep the gate loop inductance low to exploit the QR valley-switching benefits. Place VCC decoupling close to the IC per the NXP application section. Because the combo controller coordinates burst mode between stages, route feedback signals away from the LLC resonant tank to avoid coupling into burst-mode detection.
Estimated: verify junction temperature against the -40C to +150C (TJ) rating stated in distributor data. The controller itself dissipates little power, but locate it away from the PFC boost diode and LLC transformer hotspots on the PCB; in compact adapter enclosures, thermal coupling through the board can raise local ambient well above room temperature, reducing margin at high line and full load.
