TEA2095T-1J Overview
A synchronous rectifier controller is a power-management IC that replaces lossy output rectifier diodes with MOSFETs switched in synchronism with the transformer secondary voltage. In the power-conversion hierarchy it sits at the secondary side of an AC-DC or DC-DC system, alongside secondary-side feedback and supervisory controllers, and is a key efficiency lever in GreenChip-based SMPS designs.
Key features include two dedicated gate driver stages for SR MOSFETs, an adaptive gate drive method that saves the maximum amount of energy at any load, and operation tuned for resonant converter topologies. The adaptive approach shortens conduction time of the SR MOSFETs near zero-current crossings to prevent reverse current, avoiding the efficiency penalty of fixed-timing SR controllers.
Technically, the TEA2095T senses the drain-source voltage of the SR MOSFETs to detect conduction intervals, then drives the gates with accurate timing margins. This sensing-based method delivers robust performance over line, load, and temperature without needing primary-side synchronization signals, simplifying magnetics design and board routing in isolated converters.
Typical applications include LLC resonant converters for notebook adapters, high-density chargers, server and telecom power supplies, and any center-tapped secondary output requiring high-efficiency rectification, where low rectification losses directly reduce heatsinking requirements.
A key design consideration is careful PCB layout of the gate drive and sense loops; keep gate traces short and place the sense connections directly at the MOSFET pins to prevent false switching caused by parasitic ringing.

Typical Applications
TEA2095T-1J is suitable for 6 applications: LLC Resonant Converter Power Supplies, Notebook Adapters and Fast Chargers, Server and Telecom Power Supplies, Industrial AC-DC Power Supplies, LED Driver Power Supplies, Consumer Set-Top Box and TV Power Supplies.
LLC Resonant Converter Power Supplies
The TEA2095T-1J is purpose-built for the secondary side of LLC resonant converters, where it drives two SR MOSFETs rectifying a center-tapped secondary winding. Its drain-voltage-sensing architecture needs no primary-side synchronization signal, which simplifies the isolated boundary and magnetics design. The adaptive gate drive turns the MOSFETs off precisely near zero current, avoiding reverse-current losses that plague fixed-delay SR schemes and keeping efficiency high from light load to full load. In a typical 12 V, 200 W LLC stage, replacing Schottky rectifiers with TEA2095T-controlled MOSFETs removes several watts of conduction loss, shrinking heatsink size and improving the adapter's ability to meet CoC/DoE-class efficiency targets.
Recommended
Notebook Adapters and Fast Chargers
High-density notebook adapters and USB-PD fast chargers almost universally use LLC secondaries with synchronous rectification to hit efficiency and thermal targets in a small enclosure. The TEA2095T-1J fits this space-constrained role with a single SOIC-8 that integrates both SR drivers, halving the controller count versus two single-channel alternatives such as the NCP4305 or UCC24610. Its adaptive drive maintains efficiency across the wide load range these chargers see, from trickle charge to full 65-100 W output, while low standby losses support no-load input power limits. Short gate loops and direct drain sensing keep timing accurate despite the tight, high dv/dt layouts typical of charger PCBs.
Recommended
Server and Telecom Power Supplies
Server PSUs and telecom rectifier modules demand peak efficiencies above 94-96% to control heat in dense racks. In the LLC stage of these supplies, the TEA2095T-1J's dual adaptive SR drive minimizes secondary conduction loss at the high output currents typical of 12 V server rails, directly reducing waste heat and fan load. Because its sensing method adapts to line, load, and temperature variation, rectifier timing remains correct during burst, transient, and light-load operating modes required by server energy-saving standards. The SOIC-8 footprint also integrates cleanly into the multi-board or card-based formats common in telecom rectifiers, where board area and height are both constrained.
Recommended
Industrial AC-DC Power Supplies
Industrial power supplies for automation, instrumentation, and control benefit from the TEA2095T-1J's robust, sensing-based SR control, which operates reliably over wide line and load ranges without primary-side feedback wiring. In 24 V or 12 V industrial rails derived from LLC converters, the adaptive gate drive preserves efficiency at the light standby loads these systems spend most of their life in, while full-load performance reduces enclosure heating in sealed DIN-rail or panel-mount formats. Using one SOIC-8 for both rectifier MOSFETs simplifies the BOM and improves long-term sourcing resilience. Designers should still verify surge and stability performance of the complete supply under inrush and capacitive-load conditions per the system requirements.
Recommended
LED Driver Power Supplies
High-power LED drivers for street, industrial, and stage lighting use resonant or quasi-resonant converters where secondary rectification loss directly erodes lumens-per-watt figures. The TEA2095T-1J recovers this loss by synchronously rectifying center-tapped secondaries with adaptively timed MOSFETs, improving driver efficiency and reducing the thermal budget of the LED luminaire. Because LED drivers operate at high output currents and often in high-ambient enclosures, the reduced rectifier dissipation from SR also relieves the driver PCB's thermal design, extending electrolytic capacitor lifetime. The controller's load-adaptive timing accommodates the dimming-related deep dim and burst operating modes commonly required in professional lighting installations.
Recommended
Consumer Set-Top Box and TV Power Supplies
Set-top boxes, TVs, and home-audio products must meet strict active-mode efficiency and sub-0.5 W no-load input power regulations. An LLC secondary using the TEA2095T-1J converts more of the input power into usable output at both full load and the light loads typical of standby-adjacent operation, thanks to the adaptive gate drive that adjusts SR timing to every load condition. The dual-driver SOIC-8 consolidates what would otherwise require two single-channel SR ICs, cutting BOM cost and board space in cost-sensitive consumer power boards. Its sensing-based scheme also tolerates the wide tolerance of consumer magnetics, supporting low-cost transformer sourcing without retuning rectifier timing.

- No primary-side synchronization signal required (vs SRK2001)
Design Notes
Route the gate drive traces from the TEA2095T to each SR MOSFET as short and wide as practical, and return the gate current directly to the MOSFET source pin with a compact ground reference. Connect the drain-sense network directly at the MOSFET drain pins so switching-node ringing does not cause premature or false gate transitions. Because the IC senses drain-source voltage for timing, keep it clear of the high dv/dt node and provide a solid local ground under the controller.
Estimated: rectification loss savings scale with load current and RDS(on) - replacing a 0.5 V forward-drop Schottky at a 10 A secondary saves roughly I x dV = 5 W of conduction loss, so verify the selected SR MOSFET's RDS(on) x I^2 is well below the diode loss it replaces. Provide VCC energy harvesting per the NXP data sheet supply scheme and decouple VCC with a local ceramic capacitor placed at the IC pins to prevent supply dips during gate transitions.
Do not substitute single-channel SR controllers such as the NCP4305, UCC24610, or SRK2001 into a TEA2095T footprint - they are functionally similar but not pin-compatible, and a dual center-tapped secondary needs two channels of coordinated timing. Also note NXP's data sheet hierarchy: the full product data sheet prevails over the short data sheet, so confirm all electrical limits (VCC, gate drive, sensing range) against the full TEA2095T specification before release to production.
