TEA2095T Overview
A synchronous rectifier controller replaces the lossy output rectifier diodes of an SMPS with MOSFETs that are actively gate-driven, drastically cutting conduction losses. In a center-tapped LLC converter, two SR MOSFETs alternately rectify the two half-cycles; a dual SR controller such as the TEA2095T senses the drain voltages of both MOSFETs and drives the correct gate at the correct time. This device family sits in the NXP secondary-side AC-DC controller hierarchy under power management ICs and is part of the GreenChip energy-efficiency portfolio.
The defining feature of the TEA2095T is its adaptive gate drive method. Instead of a fixed minimum on-time, the controller continuously adapts the gate-drive window to the actual conduction interval of each SR MOSFET, maximizing energy savings at any load. This prevents both premature turn-off (body-diode conduction losses) and late turn-off (cross-conduction and reverse-current risks), which are the two classic failure modes of synchronous rectification in resonant converters.
The TEA2095T provides two driver stages, one per SR MOSFET, with direct drain sensing on the DSA and DSB pins. NXP documentation notes an interlock delay time with a typical value of 200 ns, which guarantees non-overlap between the two gate outputs even under transient conditions, protecting the SR MOSFETs from shoot-through. Internal circuitry connected to the DSA and DSB pins should not be polluted with series resistors, as NXP's application guidance explains that added resistance can degrade the adaptive-drive regulation through voltage offset.
Typical applications include LLC resonant converters in adapters and chargers for notebooks, high-power USB-PD chargers, LED driver power supplies, server and telecom auxiliary power stages, and TV power boards, wherever high efficiency across light and full load is mandated by energy regulations such as CoC and DoE.
A key design consideration: when migrating from the older TEA1795T, note that the DSA/DSB inputs behave differently, and the NXP community guidance warns that series resistors on these pins can degrade regulation; a PCB review is advised.

Typical Applications
TEA2095T is suitable for 6 applications: LLC Resonant Converter Secondary Rectification, High-Power USB-PD and Notebook Adapters, TV and Monitor Power Boards, Server and Telecom Auxiliary Power Supplies, LED Driver Power Supplies, Battery Charger and Adapter Efficiency Upgrades.
LLC Resonant Converter Secondary Rectification
The primary application of the TEA2095T is synchronous rectification on the secondary side of LLC resonant converters with center-tapped transformer outputs. Its two integrated adaptive gate-drive stages drive the two SR MOSFETs that alternately rectify each half-cycle, replacing Schottky diodes and cutting conduction losses dramatically at low output voltages and high currents. The adaptive method senses the drain voltage via DSA and DSB and gates each MOSFET exactly during its true conduction interval, avoiding body-diode loss at turn-off and reverse current at turn-on. The 200 ns typical interlock delay guarantees non-overlap, while direct drain sensing without series resistors preserves regulation accuracy as NXP application guidance requires.
Recommended
High-Power USB-PD and Notebook Adapters
High-power USB Power Delivery chargers and notebook adapters increasingly use LLC topologies to meet CoC Tier 2 and DoE Level VI efficiency limits, and the secondary side is where the last points of efficiency are won. The TEA2095T's adaptive gate drive saves the maximum energy at any load, which matters because adapters spend much of their life at partial load, where fixed-timing SR controllers either idle the MOSFET too briefly or leave it on too long. With its 8-pin SO footprint and dual drivers in one IC, the TEA2095T reduces BOM count versus two single-channel SR controllers, while the direct drain-sense inputs keep the adaptive window accurate despite wide input-voltage swings of the LLC bulk rail.
Recommended
TV and Monitor Power Boards
Television and monitor power boards commonly employ an LLC half-bridge stage to generate the 12 V and 24 V rails, with a center-tapped or full-wave secondary. The TEA2095T fits this secondary directly: its dual driver stages rectify the center tap, and its GreenChip control philosophy targets the standby and light-load efficiency that energy-star regulations demand. Because the drain-sense inputs tolerate the resonant node swings, the controller maintains correct gating across the whole line-voltage range. Designers migrating legacy TEA1795T-based TV boards should follow NXP's migration note: remove any series resistors on DSA/DSB, since TEA2095 internal pin circuitry makes such resistors counterproductive.
Recommended
Server and Telecom Auxiliary Power Supplies
Server and telecom systems use LLC-based auxiliary and intermediate-bus converters where every percentage point of efficiency reduces cooling cost. The TEA2095T contributes at the secondary by synchronously rectifying center-tapped outputs with adaptive timing that tracks the resonant operation over the entire load profile, from idle to full load. The single-IC dual-driver architecture halves controller count compared with two discrete SR controllers, improving reliability and layout density in cramped rack power supplies. The 200 ns interlock dead time also provides robust behavior during burst and transient modes common in cloud-server duty cycles, protecting the SR MOSFETs from simultaneous-conduction faults during load steps.
Recommended
LED Driver Power Supplies
High-bay and commercial LED drivers adopted LLC resonant stages for high efficiency and low EMI, and the output rectification loss is significant at the multi-amp LED currents involved. Placing the TEA2095T on the center-tapped secondary converts rectifier diode drops (0.5 V or more each) into I x RDS(on) losses that can be several times lower, directly improving driver efficiency and reducing heatsink size. The adaptive gate drive is particularly valuable in LED drivers that dim by phase-cut or PWM at the input, because the operating point sweeps continuously; the TEA2095T follows the changing conduction intervals automatically rather than relying on fixed timers that mis-gate under dimming transients.
Recommended
Battery Charger and Adapter Efficiency Upgrades
Legacy adapters designed with diode rectification or first-generation SR controllers can be upgraded by redesigning the secondary around the TEA2095T to satisfy newer efficiency regulations without changing the primary LLC stage. The adaptive gate-drive method yields measurable efficiency gains across the load range, which directly lowers no-load and average-mode power figures used for compliance marking. Because the controller integrates both drivers and needs only drain and gate connections plus supply, the retrofit footprint is small. Note the migration caveat from NXP: the DSA/DSB sensing differs from older GreenChip SR parts, so sense lines should connect directly without added series resistance for correct regulation.

Design Notes
Connect the DSA and DSB drain-sense pins directly to their SR MOSFET drains without series resistors. According to NXP's official community guidance on TEA1795T-to-TEA2095T migration, the TEA2095 has different internal circuitry on these pins, and added resistors can degrade the regulation of the adaptive gate drive because of voltage offset from the small currents flowing into DSA and DSB. Keep the drain-sense traces short and routed away from the gate-drive nets to avoid capacitive coupling that could disturb the adaptive timing window.
Power the TEA2095T VCC from a clean secondary-side auxiliary winding or a regulated bias rail, and decouple with a ceramic capacitor placed immediately at the VCC pin. Gate-drive switching of two SR MOSFETs creates pulsed supply currents; an undersized decoupling network causes VCC dips that can reset the controller mid-cycle. Verify the VCC range and UVLO thresholds against the current NXP datasheet values before finalizing the bias winding design, as those figures should be taken from the official document rather than from secondary sources.
Do not treat the TEA2095T as a drop-in for the older TEA1795T. Beyond the DSA/DSB sensing difference, the interlock delay time has a typical value of 200 ns on the TEA2095, which changes the non-overlap budget in the layout of the center-tap secondary. When migrating, re-check dead-time margins against your SR MOSFET switching times, and simulate light-load behavior, where the adaptive gate drive shortens on-times and body-diode conduction intervals appear at each half-cycle transition.
Compliance Information
Compliance details were not present in the retrieved web data. NXP GreenChip controllers are typically RoHS-compliant, but this must be confirmed on the official NXP TEA2095T product page before procurement decisions.
