Product details
Overview
TEA2016AAT/2 from NXP Semiconductors is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. It integrates both DCM/QR-mode PFC control and LLC resonant control in a single SO16 package, regulates output power via primary capacitor voltage (not frequency), supports three programmable operating modes (high-power/low-power/burst), and delivers <75 mW no-load input power in combination with TEA2095T - enabling Energy Star and EU Eco-design compliant 90–500 W adapters and PC power supplies.
For engineers reviewing the TEA2016AAT/2 datasheet, TEA2016AAT/2 pinout, TEA2016AAT/2 application, or TEA2016AAT/2 equivalent, key selection considerations include its VCAP-based regulation architecture, independently configurable protections (OCP/OVP/OTP/OPP/CMR), integrated HV start-up and X-cap discharge, valley/zero-voltage switching capability, and MTP-programmable transition levels between operating modes.
Technical Context
The TEA2016AAT/2 implements a digital hardware state machine-not firmware-ensuring deterministic real-time response for LLC and PFC control loops. Its regulation core measures divided primary resonant capacitor voltage (SNSCAP) to compute output power linearly, eliminating frequency-dependent gain variation and enabling stable low-load regulation.
It features dual-supply architecture: HV start-up via DRAINPFC pin charges SUPIC; operational supply derived from LLC auxiliary winding; high-side driver floating supply (SUPHS) bootstrapped from GATELS output per US Patent 82059363US01. All protections-including capacitive mode regulation (CMR), inrush current protection (ICP), and brown-in/brown-out detection-are parameterized in MTP memory and support latched/safe-restart/disable-after-attempts behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PFC Mode | Discontinuous Conduction Mode (DCM) and Quasi-Resonant (QR) - enables high efficiency at light loads and reduced EMI |
| LLC Regulation Method | Voltage across primary resonant capacitor (SNSCAP) - provides linear power-to-voltage relationship and constant-loop-gain control |
| No-Load Input Power | <75 mW (with TEA2095T) - meets Energy Star v3.0, DoE Level VI, and EU Eco-design Tier 2 requirements |
| Operating Modes | High-power mode (continuous switching), low-power mode (3-half-cycle burst with energy-per-cycle boost), and burst mode - all programmable via MTP |
| Protection Features | OCP, OVP, OTP (internal/external), OPP, CMR, OLP, UVP, ICP, brown-in/brown-out, disable input - each independently configurable for latch/safe-restart behavior |

FAQ
What is the primary regulation method used by the TEA2016AAT/2?
The TEA2016AAT/2 regulates output power by measuring the voltage across the primary resonant capacitor (via SNSCAP pin) rather than adjusting switching frequency. This VCAP-based method provides a linear relationship between ΔVCr and delivered power, ensuring stable loop gain across all load conditions - a fundamental distinction from conventional frequency-controlled LLC controllers. This architecture is implemented in the TEA2016AAT/2's digital hardware state machine.
Does the TEA2016AAT/2 require an external microcontroller or firmware?
No, the TEA2016AAT/2 operates autonomously using a high-speed configurable hardware state machine - not software or firmware. Configuration is stored in on-chip multi-time programmable (MTP) memory and loaded at startup; no external MCU, code compilation, or runtime updates are needed. All control logic, protection responses, and mode transitions execute deterministically in hardware, as confirmed in the TEA2016AAT/2 product data sheet Rev. 1.
How does the TEA2016AAT/2 achieve <75 mW no-load input power?
The TEA2016AAT/2 achieves <75 mW no-load input power through coordinated low-power and burst modes, integrated X-capacitor discharge (via DRAINPFC), valley/zero-voltage switching, and regulated optocoupler current (85 µA at SNSFB). These features are co-optimized in the TEA2016AAT/2's digital architecture and validated in combination with TEA2095T - meeting Energy Star v3.0, DoE Level VI, and EU Eco-design Tier 2 requirements without auxiliary supplies.
Can the TEA2016AAT/2 be used without the TEA2095T companion IC?
Yes, the TEA2016AAT/2 can operate standalone with discrete external MOSFETs and gate drivers, but the <75 mW no-load specification and full feature set (e.g., integrated X-cap discharge, optimized burst timing) are validated only in the TEA2016AAT/2 + TEA2095T reference design. Using the TEA2016AAT/2 alone requires careful layout of HV nodes and external bootstrap management, and may increase no-load power beyond regulatory limits.
What protections are configurable in the TEA2016AAT/2 and how are they programmed?
The TEA2016AAT/2 supports independent configuration of OCP, OVP, OTP, OPP, CMR, UVP, ICP, and brown-in/brown-out protections - each with programmable thresholds, timers, and response types (latch, safe restart, or restart-after-attempts) stored in MTP memory. Programming is performed once during manufacturing using NXP's TEA2016 programming tool and JTAG interface; no field reprogramming capability is provided in the TEA2016AAT/2.
