TEA2095T-1-S30J 概述
A synchronous rectifier controller is a specialized power management IC that replaces the output rectifier diodes of a switched-mode power supply with actively driven MOSFETs. Because a MOSFET channel exhibits a far lower voltage drop than a Schottky or fast-recovery diode, SR controllers dramatically reduce conduction losses and raise overall conversion efficiency. In the power-supply hierarchy, the TEA2095T belongs to the family of secondary-side power conversion controllers used alongside LLC resonant converters and other resonant topologies.
The TEA2095T incorporates NXP's adaptive gate drive method, which evaluates the conduction state of the SR MOSFETs cycle by cycle and adjusts gate-drive timing to save the maximum amount of energy at any load. Its two integrated driver stages are dedicated to driving the SR MOSFETs that rectify the outputs of a center-tapped transformer secondary, which is the standard configuration for low-voltage, high-current LLC resonant converters.
Architecturally, the device is a dedicated controller for synchronous rectification on the secondary side of resonant converters. The adaptive algorithm extends SR operation down to light load, where conventional fixed-timing SR controllers would turn the MOSFETs off prematurely, and it guards against reverse current at low load, improving both full-load efficiency and light-load standby power - key requirements of modern energy-efficiency regulations such as those addressed by NXP's GreenChip portfolio.
Typical applications include the secondary side of LLC resonant converters in notebook adapters, server and telecom power supplies, LED TV power boards, and high-density USB-PD fast chargers, wherever a center-tapped secondary with low-output-voltage, high-output-current rectification demands minimal conduction loss.
A key design consideration is correct placement and routing of the SR sense signals; because the controller drives two MOSFETs synchronously with the resonant half-cycle, layout symmetry between the two drive channels and short, low-inductance gate loops are essential to avoid spurious turn-on and to preserve the efficiency benefit at 100 kHz-class resonant frequencies.

典型应用
TEA2095T-1-S30J 适用于 6 应用s: LLC Resonant Converter Secondary-Side Rectification, Notebook and USB-PD Fast Charger Adapters, Server and Telecom Power Supplies, LED TV and Monitor Power Boards, Industrial Auxiliary and Battery-Charging Power Supplies, High-Density DC-DC Modules and Point-of-Load Front Ends.
LLC Resonant Converter Secondary-Side Rectification
The TEA2095T is purpose-built for synchronous rectification on the secondary side of resonant converters, and its two driver stages map directly onto the center-tapped transformer secondary of a half-bridge or full-bridge LLC converter. With adaptive gate drive, the controller senses the conduction interval of each SR MOSFET cycle by cycle and adjusts turn-on/turn-off timing, so conduction losses that would otherwise be dominated by diode drops (about 0.5 V each) fall to I x Rds(on) levels. In a 12 V / 20 A output this can save several watts of loss; the 4.75 V to 38 V supply range and 90 uA consumption keep control power negligible.
推荐
Notebook and USB-PD Fast Charger Adapters
High-power adapters (65 W to 240 W) universally adopt an LLC stage with a synchronous-rectified secondary to meet CoC Tier 2 and DoE Level VI efficiency limits. The TEA2095T fits this role because its adaptive gate drive maintains high efficiency from full load down to light load, where fixed-timing SR controllers degrade efficiency or risk reverse current. Its 8-SOIC package occupies minimal board area, and the -40C to +125C junction rating tolerates enclosed adapter thermals. Designers pair it with low-Rds(on) 30 V to 60 V SR MOSFETs and verify sense-pin routing for clean half-cycle synchronization.
推荐
Server and Telecom Power Supplies
Server PSUs and telecom rectifiers use LLC resonant front ends whose secondaries are center-tapped and carry tens of amperes; even 100 mV of rectifier drop costs multiple watts. The TEA2095T's dual driver stages rectify both half-cycles synchronously, and its adaptive algorithm protects against reverse current at light load - a critical standby-power requirement in always-on server infrastructure. The 38 V maximum supply accommodates 24 V-rail-derived auxiliary supplies, and the 90 uA quiescent draw supports ORing and housekeeping circuits. Layout symmetry between the two gate channels preserves balance at 100 kHz-class resonant frequencies.
推荐
LED TV and Monitor Power Boards
LED television power boards integrate an LLC resonant converter feeding a center-tapped secondary for the 12 V main rail, and they must meet strict standby-power and average-efficiency regulations. The TEA2095T improves conversion efficiency with its two SR driver stages and adaptive gate drive, reducing rectifier losses relative to Schottky diodes at the 10 A-class 12 V output. Its 8-SOIC package suits the cost- and space-constrained single-board architecture, and the 90 uA supply current helps satisfy sub-100 mW standby budgets when combined with a low-standby primary controller.
推荐
Industrial Auxiliary and Battery-Charging Power Supplies
Industrial 24 V bus systems frequently use LLC or quasi-resonant converters with synchronous secondary rectification for battery chargers and control-rail supplies. The TEA2095T's 4.75 V to 38 V supply range tolerates wide auxiliary-rail excursions common on industrial buses, while the -40C to +125C junction rating covers unconditioned factory-floor and outdoor-cabinet environments. Adaptive gate drive maintains efficiency across the broad load range typical of battery charging, from trickle to bulk phase, avoiding the reverse-current events that fixed-timing SR controllers exhibit near charge completion.
推荐
High-Density DC-DC Modules and Point-of-Load Front Ends
Brick-style and open-frame DC-DC modules operating from 48 V telecom inputs often employ an LLC stage whose low-voltage secondary is center-tapped. The TEA2095T provides both SR gate drives from one 8-SOIC controller, minimizing component count and board area in power-dense modules. Because the controller is secondary-side and self-powered from a 4.75 V to 38 V rail, no optocoupler or primary-side signal is needed for SR timing; the adaptive method derives timing from the SR MOSFET conduction itself, which also makes the module tolerant of burst-mode operation at light load.

关键差异点
- Dual integrated SR driver stages for center-tapped secondaries （对比 NCP4305 (onsemi))
- Adaptive gate drive across all loads （对比 Fixed-timing SR controllers)
- Wide 4.75 V to 38 V supply with 90 uA consumption （对比 TEA2095T/1J)
设计说明
Keep the two SR gate-drive loops short, symmetrical, and low-inductance. Because the TEA2095T drives two MOSFETs synchronously with the resonant half-cycles, mismatched trace lengths between the controller and the two SR MOSFETs introduce timing skew that degrades efficiency at light load and can cause spurious turn-on. Route the sense/supply traces away from the gate traces, and use a solid ground plane under the controller to return gate-drive current with minimal loop area.
The controller accepts 4.75 V to 38 V on its supply pin with only 90 uA consumption, but verify the auxiliary rail stays within range during all transients, including output short-circuit and startup bursts. Feed the controller from a small ceramic decoupling capacitor (typ. 100 nF) placed directly at the 8-SOIC supply pin, supplemented by bulk capacitance, to prevent supply dips during gate-charge delivery to the two SR MOSFETs.
Do not substitute cross-brand single-channel SR controllers (e.g., onsemi NCP4305, TI UCC24610, STMicroelectronics SRK2001) onto a TEA2095T footprint: they have different packages, pinouts, and only one driver channel, so a redesign is mandatory. Similarly, when selecting TEA2095T orderable suffixes, confirm the exact suffix (e.g., /1/S30J vs /1J) against the NXP ordering information, as suffixes encode package and packing differences that affect tape-and-reel quantity and footprint availability.
