MPN: TEA2096T/1J ✓ NakahandaTEA2096T/1J Ulas
A synchronous rectifier controller replaces the rectifier diodes on the secondary side of an SMPS with MOSFETs driven by a dedicated controller, dramatically reducing conduction losses. Within the power management hierarchy, the TEA2096T sits in the secondary-side controller category of switching controller ICs. Where a diode drop of 0.5 V to 0.7 V wastes power at high output currents, a synchronously driven MOSFET with low RDS(on) can cut that loss by a factor of 5 to 10, which is why SR controllers are standard in high-efficiency adapters and server power stages.
Key characteristics of the TEA2096T include its dual-channel architecture (two SR MOSFET drivers in one SO-8 package), an adaptive gate drive scheme that optimizes conduction time and dead-time at any load, and GreenChip design principles targeting high efficiency and low standby power. The dual-driver integration reduces external component count versus single-channel SR controllers in center-tapped secondary windings.
Technically, the TEA2096T senses the drain-source voltage of the SR MOSFETs to detect current direction, turning the gates on when the body diode conducts and off before reverse current flows. This adaptive control prevents cross-conduction and reverse-current losses that reduce efficiency in fixed-timing SR schemes, especially at light load where fixed-delay controllers typically mis-time gate transitions.
Typical applications include LLC resonant converters in AC-DC adapters, USB-PD fast chargers, and server/telecom power supplies with center-tapped or full-bridge secondary rectification. High-current 5 V and 12 V rails benefit most, where diode losses dominate.
Design consideration: proper placement of the sense lines close to the SR MOSFET drains is critical; long sense traces pick up switching noise and can cause false turn-on, degrading efficiency or damaging the MOSFETs.

LLC Resonant Converter Secondary Rectification
The TEA2096T is a dedicated synchronous rectifier controller for the secondary side of resonant converters such as LLC half-bridge and full-bridge topologies. Its two driver stages directly suit center-tapped secondary windings, where two SR MOSFETs alternate conduction each half cycle. According to the NXP data sheet, the adaptive gate drive method maximizes efficiency at any load: the controller senses current direction via the MOSFET drain-source voltage and adjusts on/off timing dynamically. This avoids the reverse-current and dead-time losses of fixed-timing SR schemes, which are most severe at light load. Result: several percentage points of efficiency gain over Schottky rectification in 12 V and 5 V outputs delivering 5 A to 30 A.

USB-PD Fast Chargers and Adapters
High-power USB-PD chargers (45 W to 140 W) use LLC or other resonant topologies with synchronous secondary rectification to meet efficiency and thermal requirements in compact enclosures. The TEA2096T fits because it integrates both SR drivers in one SO-8 package, minimizing board area in tightly constrained adapter housings, and its adaptive timing keeps SR MOSFET switching losses low across the wide load range typical of charging profiles. The GreenChip design philosophy targets high average efficiency and low standby input power, supporting regulatory efficiency standards. Typical MOSFET choices are 60 V to 100 V devices for 20 V output rails; gate-charge compatibility with the TEA2096T driver should be confirmed in the datasheet.

Server and Telecom Power Supplies
Server PSUs and telecom rectifiers demand very high efficiency at high output currents, where secondary diode losses would be prohibitive. At 12 V/50 A, a diode drop near 0.6 V dissipates roughly 30 W, whereas SR MOSFETs with RDS(on) in the low milliohm range dissipate only a few watts. The TEA2096T drives two SR MOSFETs with adaptive timing, preserving efficiency from full load to the light-load states that servers frequently occupy. SO-8 packaging supports dense power-supply layouts with parallel MOSFETs. Design attention should go to Kelvin-sensing the SR MOSFET drains with short traces to avoid false triggering from switching noise, per the datasheet layout guidance.

Industrial AC-DC Power Supplies
Industrial power supplies for PLCs, instrumentation, and factory automation use resonant converters when efficiency, density, or thermal budgets are tight. The TEA2096T provides secondary-side synchronous rectification that improves efficiency by 2 to 5 percentage points versus diode rectifiers, directly reducing heatsink size and enclosure temperature. Its adaptive gate drive compensates for the wide line and load ranges typical of industrial inputs (universal AC mains with variable loads), maintaining correct SR timing without a primary-side synchronization signal, simplifying isolation design. The SO-8 package is available from broadline distributors with same-day shipping, easing sourcing for long-lifecycle industrial products.

Battery Charging Systems
Multi-cell battery chargers for e-mobility, power tools, and energy storage use resonant AC-DC front ends with high-current low-voltage outputs. The TEA2096T's dual SR drivers fit center-tapped secondaries common in these designs, and adaptive timing prevents reverse-current discharge from the battery back through the SR MOSFETs at the end of the charge cycle - a failure mode of fixed-timing SR controllers that drains batteries in standby. Efficiency gains also reduce charge-cycle heat, protecting cell longevity. When the charger idles, proper SR control keeps no-load standby losses low, supporting energy-star type requirements for charging equipment.

LED Driver Power Supplies
High-power LED drivers for stage, street, and horticultural lighting use resonant or quasi-resonant converters where output rectification loss directly reduces lumens-per-watt. Replacing output diodes with TEA2096T-controlled SR MOSFETs raises driver efficiency, reducing LED heatsinking requirements and extending luminaire lifetime through lower internal temperatures. The controller's load-adaptive timing handles dimming-related load changes without timing misadjustment, and the dual-driver SO-8 integration fits compact LED driver PCBs. Since LED drivers run continuously for tens of thousands of hours, even small efficiency improvements compound into significant energy and thermal-relief benefits over the product lifetime.

Talaan ng Disenyo
SR controller performance depends heavily on sense-line routing. Route the drain-sense connections of both SR MOSFETs directly to their MOSFET drain pads with short, direct traces; long sense traces act as antennas for primary-side switching transients and can cause false gate activation or timing jitter. Keep the TEA2096T ground connection at a quiet point of the power ground and avoid sharing high-di/dt return paths with the sense ground reference.
Estimated: the efficiency benefit of SR versus a Schottky diode scales with output current. For example, at 10 A output, a 0.6 V diode dissipates about 6 W, while a 5 mOhm RDS(on) MOSFET dissipates about 0.5 W (P = I^2 x R). Confirm the selected MOSFET's total gate charge is within the TEA2096T driver capability per the NXP datasheet electrical characteristics before finalizing the design.
Do not substitute between NXP SR controllers (TEA2095, TEA2096) without comparing pinout and gate-drive timing behavior on the bench. These GreenChip SR controllers use adaptive timing schemes whose thresholds and blanking behavior differ between parts; a mismatch can cause cross-conduction or body-diode conduction periods that negate the efficiency benefit or overstress the MOSFETs.
