Product details
Overview
TPS62092RGTR from Texas Instruments is a 3-A synchronous step-down DC/DC converter with DCS-Control™ topology, fixed 2.5 V output, 2.5 V to 6 V input range, 2.8 MHz/1.4 MHz selectable switching frequency, and 95% peak efficiency - used in SSD power rails and processor core supplies where compact size and light-load efficiency are critical.
For engineers reviewing the TPS62092RGTR datasheet, TPS62092RGTR pinout, TPS62092RGTR application, or TPS62092RGTR equivalent, this page delivers verified electrical specs, thermal behavior, softstart timing control, hiccup-mode short-circuit protection, and voltage tracking capability for multi-rail sequencing in battery-powered embedded systems.
Technical Context
The TPS62092RGTR implements DCS-Control™ - a hybrid regulation architecture combining hysteretic response speed with voltage-mode stability - enabling seamless PWM-to-power-save mode transition without output disturbance. It uses an internal 0.8 V reference with ±1.4% feedback accuracy and supports adjustable softstart via external capacitor on SS pin.
Its dual-frequency operation (2.8 MHz default, 1.4 MHz when FREQ = high) directly scales on-time and ripple characteristics; charge pump pins (CP/CN) drive the high-side MOSFET gate using an external 10 nF flying capacitor, while VOS enables precise output voltage sensing and discharge during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V - eliminates external resistor divider, reduces BOM count and layout area. |
| Input Voltage Range | 2.5 V to 6 V - supports single-cell Li-ion (2.7–4.2 V), USB 5 V, and wide-input industrial rails. |
| Max Output Current | 3 A continuous - sustains full load under worst-case thermal conditions (RθJA = 47 °C/W). |
| Switching Frequency | 2.8 MHz (FREQ = GND) or 1.4 MHz (FREQ = VIN) - selects trade-off between component size and light-load efficiency. |
| Quiescent Current | 20 µA in power save mode - extends battery life in standby states without sacrificing wake-up response. |
| Feedback Accuracy | ±1.4% at 1 A, PWM mode - ensures tight regulation across temperature and line/load variations. |
| Thermal Shutdown | 150 °C with 20 °C hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62092RGTR is housed in a 3.0 mm × 3.0 mm, 16-pin QFN package with exposed thermal pad connected to AGND. The package supports high-density layouts and requires soldering of the thermal pad for reliable thermal performance (RθJB = 20 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 SW | Power switch node | Connects to inductor and output capacitor; carries high di/dt switching current - requires short, low-inductance routing. |
| 3 FREQ | Frequency select input | Logic-level pin: GND → 2.8 MHz, VIN → 1.4 MHz; internal 400 kΩ pull-down enables default high-frequency operation. |
| 4 PG | Open-drain power good | Signals regulation status (high-Z when VOUT ≥ 95% nominal); requires external pull-up ≤ VIN. |
| 5 FB | Feedback input | Internally tied to 0.8 V reference; for fixed-output variants like TPS62092RGTR, connect to GND to improve thermal performance. |
| 6 AGND | Analog ground | Reference for control circuitry; must be isolated from noisy PGND until joined at single point near thermal pad. |
| 7 CP / 8 CN | Charge pump terminals | Interface with external 10 nF flying capacitor to generate gate drive voltage for high-side MOSFET. |
| 9 SS | Softstart/voltage tracking | Controls startup ramp time (via external cap) or enables ratiometric output tracking when driven externally. |
| 10 AVIN | Bias supply input | Provides clean supply for analog circuitry; decouple with 100 nF ceramic capacitor close to pin. |
| 11, 12 PVIN | Main power input | High-current path for input supply; connect directly to bulk input capacitor with minimal trace inductance. |
| 13 EN | Enable input | Active-high logic; internal 400 kΩ pull-down allows direct connection to microcontroller GPIO without external resistor. |
| 14, 15 PGND | Power ground | Return path for high-current switching loop; tie to thermal pad and separate from AGND except at single star point. |
| 16 VOS | Output voltage sense | Enables Kelvin sensing for improved regulation accuracy; connect directly to output capacitor's load side. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ topology | Delivers <1% load transient deviation and <10 µs recovery time without external compensation components. |
| Adjustable softstart | Startup time set by external capacitor on SS pin (e.g., 100 nF → ~13 ms), preventing inrush current into large output caps. |
| Hiccup-mode short-circuit protection | Reduces average fault current to safe levels by cycling enable after 32 overcurrent events, avoiding thermal runaway. |
| Output discharge function | 200 Ω internal resistor discharges VOUT through VOS pin during shutdown - ensures known state before next power-on. |
| Voltage tracking support | SS pin accepts external ramp signal to coordinate startup sequence with other rails (e.g., I/O before core voltage). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62093RGTR | Fixed 1.8 V output; identical package, pinout, and feature set. | Used where lower core voltage is required (e.g., advanced SoCs), not interchangeable without board redesign. | Select TPS62093RGTR only if 1.8 V output matches system requirements - no changes to layout or support circuitry needed. |
| TPS62095RGTR | Pin-to-pin compatible; supports 2.5 V output but adds integrated softstart capacitor and enhanced EMI performance. | Preferred for new designs targeting lower radiated emissions and simplified BOM (no external SS cap required). | Choose TPS62095RGTR for EMI-sensitive applications or when reducing external component count is prioritized over legacy compatibility. |
Compared with TPS62092RGTR, TPS62093RGTR offers identical performance at 1.8 V instead of 2.5 V - ideal for newer low-voltage processors - while TPS62095RGTR retains the same 2.5 V output but integrates softstart capacitance and improves EMI behavior, making it suitable for next-generation portable electronics.

FAQ
What is the recommended inductor value for TPS62092RGTR at 2.8 MHz operation?
The TPS62092RGTR datasheet specifies a 0.47 µH inductor for 2.8 MHz operation with 22 µF output capacitance. This value balances ripple current (≈30% of IOUT), efficiency (>93% at 1.5 A), and physical size. Using a smaller inductor increases ripple and may trigger hiccup protection under heavy transient loads; larger values reduce ripple but increase DC resistance and degrade light-load efficiency.
Does TPS62092RGTR require an external softstart capacitor?
Yes, TPS62092RGTR requires an external capacitor on the SS pin to set softstart time. A typical value is 100 nF, yielding ~13 ms ramp time. Leaving SS floating results in minimum startup time (~50 µs), which may cause inrush current issues with large output capacitors. The softstart current is internally fixed at 7.5 µA, so ramp time = C × 1.25 V / 7.5 µA.
Can TPS62092RGTR operate with only PVIN connected and AVIN left unconnected?
No. Both PVIN and AVIN must be connected to the same input supply rail. AVIN powers the analog control circuitry including error amplifier and reference; omitting AVIN connection causes improper regulation, unstable output, or complete failure to start. The datasheet explicitly requires AVIN to be decoupled with a 100 nF capacitor and tied to the same source as PVIN.
What is the purpose of the VOS pin on TPS62092RGTR?
The VOS pin on TPS62092RGTR provides Kelvin sensing of the output voltage at the load, improving regulation accuracy by rejecting PCB trace IR drop. During shutdown, it also activates a 200 Ω internal discharge path to safely bleed residual charge from the output capacitor - ensuring predictable restart behavior and meeting safety requirements in battery-powered systems.
How does the FREQ pin affect efficiency and component selection in TPS62092RGTR?
Setting FREQ = GND selects 2.8 MHz operation, enabling smaller inductors (0.47 µH) and capacitors but increasing switching losses - optimal for compact designs with moderate load ranges. Setting FREQ = VIN selects 1.4 MHz, reducing switching losses and improving light-load efficiency, but requiring larger magnetics (1 µH) and higher output capacitance to maintain ripple performance. Efficiency gain at light load is typically 3–5%.
