TEA2096T Overview
A synchronous rectifier controller replaces the conventional output diodes of an SMPS secondary side with MOSFETs, switching them on only when forward current flows. Because a modern low-RDS(on) MOSFET dissipates far less power than a Schottky diode at high current, SR control is a key efficiency lever in the power-supply hierarchy (SR controller -> power supply controller -> power management IC). The TEA2096T is a dedicated secondary-side controller for synchronous rectification on resonant converters, such as LLC and partially resonant (quasi-resonant) topologies used in high-efficiency adapters and supplies.
Key features include two integrated driver stages for driving two SR MOSFETs, an adaptive gate-drive scheme that maximizes efficiency across the full load range, and GreenChip design principles that minimize standby and light-load losses. Dedicated sensing inputs allow the controller to detect the conduction state of each SR MOSFET and prevent cross-conduction and premature turn-off, which protects efficiency gains in continuous-conduction and burst modes.
Technically, the device handles the challenging SR timing problem in resonant converters: because resonant tank current is sinusoidal, naive SR control causes body-diode conduction losses or reverse-current events. The TEA2096T adaptively adjusts turn-on and turn-off timing based on measured drain-source voltage behavior, ensuring the SR MOSFETs conduct only during the proper current interval. This is especially valuable at light load and in discontinuous operation, where fixed-timing SR controllers lose efficiency or risk shoot-through.
Typical applications include LLC resonant converters in notebook adapters, USB-PD chargers, LED TV power supplies, server and telecom auxiliary supplies, and high-density industrial power modules where secondary-side diode loss dominates. Two driver channels allow a center-tapped secondary or full-wave SR arrangement from a single controller.
Design consideration: proper layout of the sense connections is critical; keep the drain-sense traces short and away from gate-driver loops to avoid false triggering from dv/dt, and follow NXP layout guidance in the TEA2096T datasheet.

Typical Applications
TEA2096T is suitable for 6 applications: LLC Resonant Converter Secondary Rectification, USB-PD Fast Chargers and Adapters, LED TV and Monitor Power Supplies, Server and Telecom Auxiliary Power, Industrial Power Modules, High-Density Notebook Adapters.
LLC Resonant Converter Secondary Rectification
The TEA2096T is purpose-built for synchronous rectification on the secondary side of LLC resonant converters. Because LLC secondary current is sinusoidal and shifts with load and input voltage, the TEA2096T's adaptive gate drive continuously retimes the SR MOSFET turn-on and turn-off to the true conduction interval, eliminating body-diode conduction losses and preventing reverse-current events. In a typical center-tapped secondary, the two integrated driver stages control both SR MOSFETs from one SO-8 IC, replacing two Schottky diodes and cutting secondary-side conduction loss substantially at outputs of 12 V to 20 V and currents of several amperes. Layout must keep drain-sense traces short to avoid dv/dt-induced false switching.
Recommended
USB-PD Fast Chargers and Adapters
USB-PD adapters operate from trickle charge to full-power profiles, so SR controllers with fixed timing lose efficiency at light load. The TEA2096T's adaptive gate drive maximizes efficiency at any load, which directly raises average efficiency and eases compliance with DoE Level VI and CoC Tier 2 external-supply efficiency requirements. Its dual driver stages suit the center-tapped secondary windings common in high-power (65 W to 240 W) GaN-based USB-PD designs, and the compact 8-SO package preserves board space in wall-cube form factors. Quiescent and burst-mode behavior must be reviewed against the no-load standby power targets in the NXP datasheet.
Recommended
LED TV and Monitor Power Supplies
Television and monitor power boards typically combine an LLC stage for the main 12 V/24 V rail with multiple buck-derived low-voltage rails. Placing the TEA2096T on the LLC secondary replaces output diodes whose loss otherwise dominates the efficiency budget at multi-ampere loads. The adaptive timing handles the wide line range (90 V AC to 264 V AC) and burst-mode operation used to meet regulatory standby limits. Because the two SR MOSFETs alternate conduction each half-cycle, the controller's independent channel sensing prevents cross-conduction during the resonant transition intervals, protecting both efficiency and reliability in cost-sensitive consumer boards.
Recommended
Server and Telecom Auxiliary Power
Server standby and telecom auxiliary converters use LLC or quasi-resonant topologies where secondary diode loss reduces the achievable efficiency at the multi-ampere 12 V output. The TEA2096T provides dual-channel SR control in an SO-8 footprint that fits dense power boards and mezzanine supplies. Its adaptive drive sustains efficiency during burst and light-load periods common in server idle states, contributing to overall platform energy metrics. Designers should verify the controller's VCC supply arrangement from the primary or an auxiliary winding per the NXP application information, and use Kelvin sensing at the SR MOSFET source to maintain accurate current-interval detection under high di/dt.
Recommended
Industrial Power Modules
Industrial 24 V and 48 V intermediate-bus converters and DIN-rail power supplies benefit from synchronous rectification to meet the efficiency and thermal targets of sealed enclosures. The TEA2096T's two driver stages allow full-wave SR on a center-tapped secondary from a single controller, reducing component count and improving Mean Time Between Failures by removing hot diodes. The adaptive scheme tolerates the wide input transients typical of industrial mains. In module designs, keep the SR MOSFET power loop compact, place the controller close to the transformer secondary, and follow NXP layout recommendations in the TEA2096T datasheet to keep drain-sense nodes free of switching noise.
Recommended
High-Density Notebook Adapters
Notebook adapters (45 W to 120 W) demand both high average efficiency and very low standby power. The TEA2096T addresses both: adaptive SR timing maintains efficiency at the light loads typical of a charged battery, while GreenChip control techniques minimize controller overhead loss. The dual-channel SO-8 controller suits the half-bridge LLC stages common in these adapters, and its small footprint leaves room for EMI filtering components constrained by CISPR limits. Designers should pair the controller with low-Qg SR MOSFETs, because the adaptive drive assumes gate speed consistent with the resonant half-cycle durations documented in the NXP product specification.

Design Notes
The TEA2096T detects the SR MOSFET conduction interval from drain-source voltage sensing. Keep the drain-sense traces short, direct, and routed away from gate-driver loops and the main power loop. Any dv/dt or di/dt coupling into the sense nodes can cause premature turn-on or turn-off, creating reverse-current loss or shoot-through. Use Kelvin connections at the SR MOSFET source for the controller ground reference, per the NXP TEA2096T datasheet application section.
Estimated: SR efficiency gain depends on replacing diode loss (approximately Vf x Iout) with MOSFET loss (Iout^2 x RDS(on)). For example, at 5 A output, a 0.5 V Schottky dissipates about 2.5 W, while a 10 mOhm SR MOSFET dissipates about 0.25 W - roughly a 2.25 W saving per SR switch. Confirm final numbers with the chosen MOSFET RDS(on) at operating junction temperature and the current waveform in your LLC design.
Do not treat the TEA2095T as a blind substitute: it is a single-channel SR controller and cannot drive the two SR MOSFETs of a center-tapped secondary. Also, controller VCC must remain within datasheet limits during startup and burst mode; an underpowered auxiliary winding can cause erratic SR gating at light load. Always confirm electrical limits in the current NXP TEA2096T product specification before releasing production files.
