Product details
Overview
TPS62095 from Texas Instruments is a 4A synchronous step-down DC/DC converter with DCS-Control™ topology, operating from 2.5V to 5.5V input and delivering adjustable output (0.8V–VIN) in a 3mm × 3mm VQFN-16 package. It achieves up to 95% efficiency at 1.8V/4A, features 20µA quiescent current in Power Save Mode, and supports 100% duty cycle for ultra-low dropout-ideal for battery-powered SSDs and processor core rails.
For engineers reviewing the TPS62095 datasheet, TPS62095 pinout, TPS62095 application, or TPS62095 equivalent, key selection criteria include its DCS-Control™ transient response, two-level hiccup short-circuit protection, soft-start programmability via SS pin, and compatibility with high-ESR-output-capacitor designs up to 150µF.
Technical Context
The TPS62095 implements DCS-Control™-a hybrid regulation architecture combining hysteretic speed with voltage-mode stability-to enable seamless PWM-to-Power-Save-Mode transition without output voltage disturbance. Its fixed ON-time control loop uses input feed-forward to maintain ~1.4MHz switching frequency across input voltage and load variations.
Internally, it integrates high-side (50mΩ) and low-side (40mΩ) MOSFETs, a charge pump for gate drive, and dedicated analog/digital power domains (AVIN/PVIN). Functional modes include adjustable soft-start (7.5µA constant-current ramp), output voltage tracking via SS pin, and 200Ω active discharge through VOS during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, USB, and wide-input industrial rails without external pre-regulation. |
| Output Current | Up to 4.0A continuous - sufficient for modern SoC cores, FPGAs, and SSD controllers. |
| Switching Frequency | 1.4MHz nominal - enables compact 1µH inductors and minimizes EMI in noise-sensitive RF systems. |
| Quiescent Current | 20µA in Power Save Mode - extends battery runtime in always-on subsystems like embedded controllers. |
| Feedback Reference | 0.8V ±1.4% - sets output accuracy baseline; used with external resistor divider (e.g., R1=200kΩ, R2=160kΩ for 1.8V). |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design. |
| Power Good Threshold | 90% to 95% of VOUT - provides reliable system sequencing signal with open-drain PG output. |
| Short-Circuit Protection | Two-level hiccup mode - limits startup current to ~1.8A below 0.6V, then escalates to full 5.5A limit and cycles on fault. |
Pinout & Package
TPS62095 is housed in a thermally enhanced 3.00 mm × 3.00 mm, 16-pin VQFN package (RGT) with exposed thermal pad soldered to AGND. The package supports ≤1.2mm total solution height and requires controlled-impedance layout per TI SLVSBD8A layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2) | Power switch node | Connects to inductor; carries high di/dt switching current-requires short, low-inductance trace and local ceramic decoupling. |
| DEF (3) | Internal logic reference | Must be tied to AVIN; enables internal bias generation and stabilizes control circuitry. |
| PG (4) | Open-drain power-good indicator | Sinks ≤1mA; requires external pull-up to ≤VIN; asserts high when VOUT is within ±5% of regulation. |
| FB (5) | Voltage feedback input | Monitors resistive divider output; regulates VOUT to 0.8V reference-accuracy directly impacts output tolerance. |
| AGND (6) | Analog ground reference | Separate from PGND; connects to thermal pad and all analog pins (AVIN, CP, CN, SS, VOS, FB) to minimize noise coupling. |
| CP/CN (7,8) | Charge pump flying capacitor terminals | Requires 10nF ceramic capacitor between them; supplies gate drive voltage for high-side MOSFET. |
| SS (9) | Soft-start timing control | Charged at 7.5µA; sets startup ramp time-floating = minimum start time; larger capacitor delays rise to reduce inrush. |
| AVIN (10) | Analog supply input | Powers internal reference, error amplifier, and control logic; must be bypassed with ≥1µF ceramic near pin. |
| PVIN (11,12) | Power input supply | High-current VIN path; connects to input capacitor and shares return with PGND pins (14,15). |
| EN (13) | Enable input with internal 400kΩ pull-down | Active-high; logic threshold is 1V min / 0.4V max; allows simple microcontroller or sequencer control. |
| PGND (14,15) | Power ground return | Low-impedance path for switch current; must be connected to input/output capacitor grounds and thermal pad. |
| VOS (16) | Output voltage sense | Direct connection to output rail; enables 200Ω active discharge during disable/shutdown to prevent floating rail. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <10µs load transient recovery with <20mV undershoot at 4A step-critical for burst-mode processors. |
| Adjustable soft-start | Programmable via SS pin capacitor; prevents inrush-induced input droop or false UVLO triggering in multi-rail systems. |
| Output voltage tracking | SS pin accepts external ramp signal to coordinate startup sequence with other rails (e.g., I/O before core). |
| 100% duty-cycle operation | Extends usable battery range by maintaining regulation down to VIN ≈ VOUT + IOUT×(RDS(on)+RL), e.g., ~2.0V for 1.8V/4A. |
| Two-level short-circuit protection | Reduces startup current limit to ~1.8A until VOUT > 0.6V, preventing inductor saturation during bulk capacitor charging. |
| Output discharge function | 200Ω internal discharge path via VOS pin ensures safe, rapid rail collapse-eliminates need for external bleed resistors. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62090RGTT | Pin-to-pin compatible; identical 3mm × 3mm VQFN-16 package and DCS-Control™ architecture but rated for 3A max output current. | Suitable for lower-power applications (e.g., microcontrollers, sensors) where 4A headroom is unnecessary. | Select TPS62090RGTT only if peak load remains ≤3A-avoids overdesign while maintaining identical layout and control behavior. |
| TPS62130ARGTR | Higher 6A rating and 2.7–6V input range; uses different regulation scheme (adaptive on-time) and larger 4mm × 4mm VQFN-16 package. | Better suited for higher-input-voltage industrial rails (e.g., 5V or 12V intermediate bus) requiring >4A. | Choose TPS62130ARGTR when input exceeds 5.5V or output current demand exceeds 4A-requires PCB footprint change and layout revalidation. |

FAQ
What is the maximum output current capability of the TPS62095RGTT?
The TPS62095RGTT delivers up to 4.0A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its internal high-side and low-side MOSFETs have RDS(on) values of 50mΩ and 40mΩ respectively, enabling this rating with typical efficiency >90% at 1.8V/4A and 3.6V input. Derating applies above 85°C ambient or with inadequate copper area.
How does the TPS62095RGTT achieve seamless transition between PWM and Power Save Mode?
The TPS62095RGTT uses TI's proprietary DCS-Control™ topology, which employs a single control loop with input feed-forward and adaptive on-time modulation. This eliminates mode-switching discontinuities-ensuring no output voltage glitch or audible noise during the transition from fixed-frequency PWM (1.4MHz) to variable-frequency Power Save Mode at light loads.
Can the TPS62095RGTT operate with a 2.5V input and deliver 1.8V at full 4A load?
Yes-the TPS62095RGTT supports 2.5V to 5.5V input and can sustain 1.8V/4A output at 2.5V input using 100% duty-cycle operation. However, efficiency drops to ~80% (per Figure D001), and thermal design must accommodate higher conduction losses; junction temperature must remain ≤125°C with adequate PCB copper and airflow.
What is the purpose of the VOS pin on the TPS62095RGTT, and how should it be connected?
The VOS (Voltage Output Sense) pin on the TPS62095RGTT provides an active discharge path (200Ω internal resistor) to safely collapse the output voltage during shutdown, disable, or fault conditions. It must be connected directly to the regulated output rail-no series resistor or RC network-to ensure rapid, controlled discharge and prevent floating voltages that could damage downstream logic.
Does the TPS62095RGTT support output voltage tracking, and how is it implemented?
Yes-the TPS62095RGTT supports voltage tracking via its SS (soft-start) pin. By injecting a controlled ramp voltage into SS (e.g., from another regulator's output), the TPS62095RGTT's output follows that ramp, enabling coordinated startup with other rails. Tracking accuracy depends on external resistor ratios and the 7.5µA SS current, with typical configurations achieving <1% tracking error.
