Product details
Overview
TPS62095RGTR 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 to VIN) in a 3mm × 3mm VQFN-16 package. It achieves up to 95% efficiency at 1.8V/4A output, features 1.4MHz fixed-frequency PWM mode, automatic seamless transition to Power Save Mode, and supports low-profile point-of-load regulation in space-constrained battery-powered systems.
For engineers reviewing the TPS62095RGTR datasheet, TPS62095RGTR pinout, TPS62095RGTR application, or TPS62095RGTR equivalent, key selection criteria include its 20µA quiescent current in Power Save Mode, 100% duty cycle capability for ultra-low dropout, two-level hiccup-mode short-circuit protection, output discharge function via VOS pin, and compatibility with up to 150µF output capacitance for enhanced transient response.
Technical Context
The TPS62095RGTR implements DCS-Control™ - a hybrid regulation architecture combining hysteretic and voltage-mode control - enabling stable operation across wide input/output ranges without external compensation. Its functional block integrates a high-side/low-side MOSFET pair (RDS(on) = 50mΩ / 40mΩ), internal charge pump for gate drive, programmable soft-start via SS pin current (7.5µA), and precision 0.8V reference with ±1.4% feedback accuracy in PWM mode.
It operates in fixed-frequency PWM mode (1.4MHz nominal) under medium-to-heavy loads and transitions seamlessly into variable-frequency Power Save Mode at light loads, maintaining >80% efficiency down to 1mA. Critical protection features include undervoltage lockout (2.2V threshold, 200mV hysteresis), thermal shutdown (150°C, 20°C hysteresis), and startup-current-limited hiccup-mode short-circuit protection triggered after 32 overcurrent events.
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 pre-regulation. |
| Output Current | Up to 4.0A continuous - enables direct powering of high-current processors, SSDs, and HDDs. |
| Switching Frequency | 1.4MHz nominal - allows use of compact 1µH inductors and minimizes EMI in RF-sensitive applications. |
| Quiescent Current | 20µA in Power Save Mode - extends battery life in always-on, low-duty-cycle IoT and portable devices. |
| Feedback Reference | 0.8V ±1.4% (PWM mode) - enables precise output setting from 0.8V to VIN using standard resistor dividers. |
| Efficiency Peak | 95% at 1.8V/4A - reduces thermal load and PCB area vs. lower-efficiency alternatives in dense layouts. |
| Duty Cycle Max | 100% - sustains regulated output down to VIN ≈ VOUT + IOUT×(RDS(on) + RL), maximizing battery utilization. |
| Short-Circuit Protection | Two-level hiccup mode - limits fault energy during sustained shorts while enabling auto-recovery. |
Pinout & Package
TPS62095RGTR is housed in a thermally enhanced 3mm × 3mm, 16-pin VQFN package (RGT suffix) with an exposed thermal pad that must be soldered to AGND for optimal thermal performance (RθJA = 47°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2) | Power switch node | Connects to external inductor; carries high di/dt switching current - requires tight layout and Kelvin connection. |
| DEF (3) | Defeat pin | Must be tied to AVIN to enable internal logic; floating or low disables device functionality. |
| PG (4) | Power good open-drain | Signals regulation status; requires external pull-up ≤ VIN - not compatible with voltages > VIN. |
| FB (5) | Feedback input | Senses output via resistor divider; 0.8V reference sets VOUT = 0.8V × (1 + R1/R2). |
| AGND (6) | Analog ground | Reference for FB, SS, CP/CN, VOS - must be isolated from PGND except at single-point thermal pad. |
| CP / CN (7,8) | Charge pump terminals | Require 10nF ceramic capacitor between pins to generate gate drive voltage for high-side FET. |
| SS (9) | Soft-start control | Charged by 7.5µA current; sets startup ramp time - floating = minimum start time (~167µs). |
| AVIN (10) | Analog supply | Powers internal analog circuitry; must be decoupled with 100nF near pin and connected to PVIN externally. |
| PVIN (11,12) | Power input | Main input supply path; accepts 2.5–5.5V - requires local 22µF ceramic input capacitor. |
| EN (13) | Enable with pull-down | Active-high; internal 400kΩ pull-down ensures default disable - driven high ≥1V to activate. |
| PGND (14,15) | Power ground | High-current return path for SW and PVIN - must be solid copper plane under IC and connected to thermal pad. |
| VOS (16) | Output voltage sense | Direct connection to output rail enables fast discharge via 200Ω internal resistor when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Enables <1% load transient deviation and <10mV output ripple without external compensation components. |
| Adjustable soft-start | Capacitor on SS pin sets controlled inrush current - prevents input rail collapse during cold boot of multi-rail systems. |
| Output voltage tracking | SS pin accepts external voltage ramp to synchronize startup with other rails - supports sequencing in multi-core SoC designs. |
| Output discharge function | 200Ω internal resistor on VOS pin actively discharges output when disabled - ensures clean power-down and avoids latch-up. |
| Low-profile solution | Supports total height ≤1.2mm with 1µH inductor and 2×22µF output caps - meets strict Z-height requirements in ultrabooks and tablets. |
| Pin-to-pin compatibility | Direct replacement for TPS62090 - enables drop-in upgrade to 4A capability without PCB redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62090RGTR | 3A rated output, identical pinout and package; lacks 4A current limit and optimized thermal design for 4A continuous operation. | Suitable for ≤3A loads only; cannot sustain 4A without derating or thermal throttling. | Select TPS62090RGTR only if peak load remains below 3A and board layout does not support thermal pad rework. |
| TPS62130ARGTR | 6A rating, 2.95–6V input, 2.5MHz switching frequency; larger 4mm × 4mm VQFN package with different pinout. | Requires PCB redesign due to non-pin-compatible layout and higher minimum input voltage. | Choose TPS62130ARGTR only when >4A headroom or >5.5V input is required - not a drop-in replacement. |
Compared with TPS62095RGTR, TPS62090RGTR offers identical feature set at reduced current capability, while TPS62130ARGTR provides higher current and input range at the cost of larger footprint and layout changes - making TPS62095RGTR the optimal balance of size, efficiency, and 4A performance in space-constrained 2.5–5.5V systems.

FAQ
What is the maximum continuous output current supported by the TPS62095RGTR?
The TPS62095RGTR supports up to 4.0A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Its switch current limit is specified at 4.7–6.7A, but sustained 4A operation requires adequate copper area on PGND and thermal pad connection to maintain junction temperature below 125°C.
Does the TPS62095RGTR require external compensation components?
No, the TPS62095RGTR does not require external compensation components. Its integrated DCS-Control™ topology provides inherent stability across all input/output combinations and output capacitor values up to 150µF, eliminating the need for loop compensation networks and simplifying design validation.
How does the soft-start function work on the TPS62095RGTR?
The TPS62095RGTR charges an external capacitor on the SS pin with a constant 7.5µA current. The FB voltage ramps proportionally (VFB = VSS/1.56) until reaching 0.8V, controlling inrush current. With no capacitor, startup completes in ~167µs; a 100nF capacitor extends it to ~13.3ms - enabling safe sequencing in multi-rail systems.
Can the TPS62095RGTR operate with input voltage below 2.5V?
No, the TPS62095RGTR has a guaranteed operating input range of 2.5V to 5.5V. Its undervoltage lockout activates below typically 2.2V (with 200mV hysteresis), disabling the device. Operation below 2.5V is outside specification and may result in unstable regulation or failure to start.
What is the purpose of the VOS pin on the TPS62095RGTR?
The VOS pin on the TPS62095RGTR provides direct sensing of the output voltage and enables the internal 200Ω discharge resistor. When the device is disabled (EN low), thermal shutdown occurs, or UVLO triggers, the VOS pin actively discharges the output capacitor to prevent residual voltage from interfering with system reset or causing latch-up in downstream logic.
