TEA2226AT Digital Configurable LLC Controller
The TEA2226AT is a digital configurable controller for high-efficiency resonant power supplies. The power supply is easy to design and has a very low component count. It meets the efficiency regulations of Energy Star, the Department of Energy (DoE), the Eco-design directive of the European Union, the European Code of Conduct, and other guidelines. So, no auxiliary low-power supply is required.
Product Details
Features
Distinctive Features
- LLC controller in a 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
- Integrated X-capacitor discharge without additional external components
- Power good function
-
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
- 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 TEA2226AT/TEA2095T combination)
Protection Features
- 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)
- Brownin/brownout protection
- Disable input
- Input to reset all protections
Product Longevity Program
- This product is included in the NXP Product Longevity program with assured supply for a minimum of 10 years after launch
Part numbers include: TEA2226AT.
