NXP Semiconductors TEA2017AAT LLC & Multimode PFC Controller

NXP Semiconductors TEA2017AAT LLC and Multimode PFC Controller is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. The device includes an LLC controller and PFC controller functionality. The TEA2017AAT can help users build a complete resonant power supply, making it easy to design with a low component count.

The digital architecture is based on a high-speed configurable hardware state machine, ensuring reliable real-time performance. Each configuration can be secured to prevent unauthorized copying of the proprietary NXP Semiconductors TEA2017AAT configuration content. The device comes in a low profile and narrow body-width SO16 package.

Features

Complete functionality of a PFC and LLC controller in a single small-size SO16 package
Integrated high-voltage start-up
Integrated drivers and high-voltage level shifter (LS)
The high-side driver directly supplied from the low-side driver's output
Accurate boost voltage regulation
PFC can be configured to operate in
- DCM/QR
- DCM/QR/CCM (also called multimode 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 the 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

Valley/zero voltage switching for minimum switching losses
Extremely high efficiency from low load to high load
Compliant with the most current energy-saving standards and directives (Energy Star, EuP)
Excellent no-load input power (< 75 mW for TEA2017AAT/TEA2095T combination)
Independently configurable levels and timers
Many 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)
- Brown-in/brown-out protection
- Disable input
