Digital Configurable LLC and Multimode PFC Controller
The TEA6017AT is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. It includes both the LLC controller and PFC controller functionality. The PFC can be configured to operate in DCM/QR, CCM fixed frequency, or multimode which supports all operation modes to optimize the PFC efficiency. The TEA6017AT enables building a complete resonant power supply which is easy to design and has a very low component count. The TEA6017AT comes in a low profile and narrow body-width SO16 package.
The TEA6017AT digital architecture is based on a high-speed configurable hardware state machine ensuring very reliable real-time performance. During the power supply development, many operation and protection settings of the LLC and PFC controller can be adjusted by loading new settings into the device to meet specific application requirements. The configurations can be fully secured to prevent unauthorized copying of the proprietary TEA6017AT configuration content.
In contrast to traditional resonant topologies, the TEA6017AT shows a very high efficiency at low loads due to the LLC low-power mode. This mode operates in the power region between continuous switching (also called high-power mode) and burst mode.
The TEA6017AT complies fully to NXP’s profile for industrial applications.

Features
Distinctive Features
- Complete functionality of LLC and PFC controller in single small-size SO16 package
- Integrated high-voltage start-up
- Integrated drivers and high-voltage level shifter (LS)
- High-side driver directly supplied from the low-side driver output
- Accurate boost voltage regulation
-
PFC can be configured to operate in:
- DCM/QR
- DCM/QR/CCM (also called mixed mode operation)
- CCM fixed frequency
- Integrated X-capacitor discharge without additional external components
- Power good function
- PFC jitter for optimized EMI performance
- Excellent power factor (PF) and total harmonic distortion (THD), as the PFC current compensates for the input filter current
-
Several parameters can easily be configured during evaluation with
use of the graphical user interface (GUI), like:
- Operating frequencies to be outside the audible area at all operating modes
- Soft start and soft stop in burst mode, reducing the audible noise
- Accurate transition levels between operation modes (high-power mode/low-power mode/burst mode)
- Enabling/disabling the lower power mode
Green Features
- Valley/zero voltage switching for minimum switching losses
- Extremely high efficiency from low load to high load
- Compliant with latest energy-saving standards and directives (Energy Star, EuP)
- Excellent no-load input power (< 75 mW for TEA2017AAT/TEA2095T combination)
Protection Features
- Independently configurable levels and timers
- All protections can independently be set to latched, safe restart, or latched after several attempts to restart
- Supply undervoltage protection (UVP)
- Overpower protection (OPP)
- Internal and external overtemperature protection (OTP)
- Capacitive mode regulation (CMR)
- Accurate overvoltage protection (OVP)
- Overcurrent protection (OCP)
- Inrush current protection (ICP)
- Brownin/brownout protection
- Disable input
