Product details
Overview
TPS62097RWKT from Texas Instruments is a synchronous step-down DC-DC converter with iDCS-Control topology, supporting 2-A output current, 2.5-V to 6.0-V input range, and adjustable or fixed 1.8-V/3.3-V outputs. It delivers up to 97% efficiency in forced PWM mode and features ±1% output voltage accuracy, hiccup short-circuit protection, and power-good signaling - deployed in noise-sensitive POL applications for industrial motor drives and SSDs.
For engineers reviewing the TPS62097RWKT datasheet, TPS62097RWKT pinout, TPS62097RWKT application, or TPS62097RWKT equivalent, key selection considerations include its 11-pin VQFN (RWK) package, selectable 1.5–2.5 MHz switching frequency via MODE pin resistor, 100% duty cycle capability for ultra-low dropout, programmable soft-start via SS/TR pin, and integrated output discharge during shutdown.
Technical Context
The TPS62097RWKT implements iDCS-Control - a predictive on-time architecture enabling seamless transition between PWM and Power Save Mode (PSM), or forced fixed-frequency PWM across full load range. Its control loop uses input/output voltage feedforward to maintain quasi-constant switching frequency while achieving ±1% output regulation without external compensation.
It integrates dual MOSFET power switches with typical RDS(on) of 40–96 mΩ (high-side) and 40–85 mΩ (low-side), supports output voltage tracking via SS/TR pin, and provides hiccup-mode short-circuit protection triggered after 32 current-limit events. Thermal shutdown activates at 160°C with 20°C hysteresis, and undervoltage lockout engages below 2.3 V (rising).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 6.0 V - supports single-cell Li-ion, USB PD, and industrial 3.3/5-V rails without pre-regulation. |
| Output Current | Up to 2 A continuous - sufficient for FPGA core rails, microcontroller I/O supplies, and SSD controller power domains. |
| Output Voltage Options | Adjustable (0.8 V to VIN) or fixed 1.8 V / 3.3 V - enables direct replacement of legacy LDOs with higher efficiency. |
| Efficiency | Up to 97% at medium-to-heavy loads in PWM mode - reduces thermal load in compact enclosures and extends battery runtime. |
| Switching Frequency | Selectable 1.5–2.5 MHz via MODE pin resistor - allows EMI optimization and small external component sizing (e.g., 1-µH inductor). |
| Accuracy & Regulation | ±1% output voltage accuracy; 0.2%/A load regulation - ensures stable logic-level compliance under dynamic load transients. |
| Protection Features | Hiccup short-circuit, thermal shutdown (160°C), UVLO (2.3 V), output discharge - eliminates need for external fault-handling circuitry. |
Pinout & Package
TPS62097RWKT is housed in an 11-terminal, 2.0 mm × 2.0 mm VQFN package (RWK suffix), thermally enhanced with exposed PGND pad for low-junction-to-board resistance (RθJB = 19.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND | Power ground | Main return path for high-current switch node; must be connected directly to thermal pad and low-impedance ground plane. |
| SW | Switch node | Connects internal high/low-side MOSFETs to external inductor; requires tight layout to minimize EMI and ringing. |
| VOS | Output voltage sense | Direct connection point to output capacitor cathode - critical for accurate regulation and fast transient response. |
| FB | Feedback input | Sets output voltage via resistor divider (adjustable) or tied to AGND (fixed versions); internal 400-kΩ pull-down when unused. |
| PG | Power-good open-drain | Signals valid output (95% VOUT) with 1-mA sink capability; used for rail sequencing with external pull-up ≤6 V. |
| EN | Enable input | Active-high logic control with 375-kΩ internal pulldown; enables/disables converter and triggers output discharge. |
| PVIN | Power input supply | High-current VIN path for power switches - separate from AVIN to isolate noise-sensitive analog circuitry. |
| AVIN | Analog supply input | Bias supply for control circuitry; must be connected to PVIN externally to ensure proper startup and regulation. |
| SS/TR | Soft-start & tracking | Charged by 7.5-µA current for controlled ramp-up; also accepts external voltage for ratiometric or coincident rail tracking. |
| MODE | Mode selection | Determines PWM/PSM auto-transition (AGND) or forced PWM only (resistor/open); sets switching frequency per Table 8-1. |
| AGND | Analog ground | Reference for FB, MODE, SS/TR, and internal error amplifier - must be star-connected to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| iDCS-Control topology | Enables seamless PWM-to-PSM transition and forced PWM operation - eliminates output voltage glitches during mode change. |
| Programmable soft start | External capacitor on SS/TR pin sets ramp time (tSS ≈ 0.8 V / 7.5 µA × CSS) - prevents inrush current into downstream capacitance. |
| Output voltage tracking | SS/TR pin accepts external voltage reference to coordinate startup/shutdown timing with other rails - supports multi-rail SoC sequencing. |
| 100% duty cycle mode | High-side FET remains on when VIN ≈ VOUT - maintains regulation down to ~15% above output voltage, minimizing dropout loss. |
| Integrated output discharge | 165-Ω internal resistor discharges VOUT via VOS pin during disable/UVLO/thermal fault - avoids floating outputs and improves system safety. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6209718RWKT | Fixed 1.8-V output; identical pinout, package, and feature set - differs only in internal feedback divider. | Eliminates external resistor network for 1.8-V designs; same thermal performance and efficiency curve. | Select when fixed 1.8-V output suffices and board space for FB resistors is constrained. |
| TPS628512RQWR | 2-A, 6-V input, SOT583 package; lower quiescent current (25 µA), smaller footprint (1.6 mm × 2.1 mm), but no VOS pin or output discharge. | Lacks output voltage sense (VOS) and discharge functionality - unsuitable for systems requiring precise remote sensing or safe shutdown discharge. | Prefer for space-constrained, battery-powered applications where VOS and discharge are non-critical. |
Compared with TPS62097RWKT, TPS6209718RWKT offers identical performance with simplified layout for 1.8-V use cases, while TPS628512RQWR trades VOS sensing and discharge for smaller size and lower IQ - making TPS62097RWKT optimal for industrial POLs needing robust fault handling and precision regulation.

FAQ
What is the package type and pin count of the TPS62097RWKT?
The TPS62097RWKT uses an 11-pin VQFN package with 2.0 mm × 2.0 mm body size and RWK designation. It features an exposed thermal pad (PGND) for enhanced heat dissipation and meets JEDEC MO-220 standards. Pin compatibility is confirmed per TI's SLVSCD6A datasheet Figure 6-1 and Table 6-1.
Does the TPS62097RWKT support fixed output voltages?
Yes, the TPS62097RWKT supports adjustable output (0.8 V to VIN) via external resistor divider on FB/VOS pins. Fixed-output variants exist (TPS6209718RWKT = 1.8 V, TPS6209733RWKT = 3.3 V), but the base TPS62097RWKT itself is adjustable - requiring R1/R2 per Equation 4 in the datasheet.
How does the MODE pin configure switching behavior on the TPS62097RWKT?
The MODE pin on the TPS62097RWKT selects both operating mode and switching frequency: grounding it to AGND enables automatic PWM/PSM transition; connecting it to specific resistors (8.2 kΩ to 75 kΩ) or leaving it open forces fixed-frequency PWM at 1.5–2.5 MHz. Configuration occurs during a 50-µs detection window after EN assertion.
What protection features are integrated into the TPS62097RWKT?
The TPS62097RWKT integrates hiccup short-circuit protection (32-event latch-off), thermal shutdown (160°C trip, 20°C hysteresis), undervoltage lockout (2.3 V rising threshold), and output discharge (165-Ω internal resistor). All activate automatically without external components - ensuring robust operation in industrial environments.
Can the TPS62097RWKT perform voltage tracking with other power rails?
Yes, the TPS62097RWKT supports voltage tracking via its SS/TR pin: applying an external ramp voltage (0–0.8 V) causes the FB reference to follow proportionally, enabling ratiometric or coincident startup/shutdown with other regulators. Tracking is disabled above 0.8 V, reverting to standard 0.8-V reference regulation.
