Product details
Overview
TPS62097RWKR from Texas Instruments is a 2-A synchronous step-down DC/DC converter with iDCS-Control topology, forced PWM or power-save mode operation, and selectable 1.5–2.5 MHz switching frequency. It delivers ±1% output voltage accuracy across 0.8 V to VIN output range, supports 100% duty cycle for ultra-low dropout, and integrates power-good signaling, hiccup short-circuit protection, and programmable soft start. It serves as a high-efficiency POL regulator in noise-sensitive industrial power rails.
For engineers reviewing the TPS62097RWKR datasheet, TPS62097RWKR pinout, TPS62097RWKR application, or TPS62097RWKR equivalent, key selection considerations include its 2-mm × 2-mm VQFN-11 package, dual-mode control (PWM/PSM), 2.5–6.0 V input range, integrated output discharge, and thermal shutdown with 160°C trip point - all critical for compact, reliable, and low-noise embedded power designs.
Technical Context
The TPS62097RWKR implements iDCS-Control, combining predictive on-time PWM with seamless transition into Power Save Mode at light loads - or forced fixed-frequency PWM across full load range via MODE pin configuration. Its internal compensation supports >150 µF output capacitance, enabling stable regulation with large ceramic or polymer caps.
It features dual current-sense paths: high-side FET forward limit (3.1–4.2 A) and low-side FET negative current limit (–1.25 to –0.7 A in forced PWM), plus undervoltage lockout (2.3 V nominal) with 100 mV hysteresis and active output discharge (165 Ω) during disable or fault conditions.
Key Specifications

| Output Voltage Accuracy | ±1% in PWM mode - ensures tight regulation for sensitive analog circuitry and precision ADC references. |
| Switching Frequency | Selectable 1.5–2.5 MHz - enables compact magnetics and EMI filtering while avoiding AM band interference. |
| Efficiency | Up to 97% - minimizes thermal load in sealed enclosures and extends battery runtime in portable industrial tools. |
| Junction Temperature Range | –40°C to 125°C - qualified for under-hood automotive auxiliary rails and industrial PLC backplanes. |
| Quiescent Current | 40–65 µA - preserves battery life in always-on monitoring nodes during sleep states. |
Pinout & Package
TPS62097RWKR is housed in a thermally enhanced 2-mm × 2-mm VQFN-11 package (RWK suffix) with exposed thermal pad on underside for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND | Power ground | Primary 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- and low-side MOSFETs; drives external inductor; requires tight layout to minimize EMI and ringing. |
| VOS | Output voltage sense | Direct connection point to output capacitor anode - enables accurate remote sensing and fast transient response. |
| FB | Feedback input | Monitors divided output voltage; internal 400-kΩ pull-down allows floating in fixed-output variants; sets regulation point at 0.8 V reference. |
| PG | Power-good open-drain | Signals valid output regulation (95% threshold); requires external pull-up ≤6 V; used for rail sequencing with other converters. |
| EN | Enable input | Active-high logic control with 375-kΩ internal pulldown; enables/disable sequencing and system-level power management. |
| PVIN | Main power input | High-current path for input supply; decoupled separately from AVIN to reduce noise coupling into analog circuitry. |
| AVIN | Analog supply input | Bias rail for internal reference, error amplifier, and control logic; tied to PVIN but routed with local 100-nF ceramic cap. |
| SS/TR | Soft-start/voltage tracking | Controls ramp rate via external capacitor (7.5 µA charge current); also accepts external voltage for coordinated multi-rail startup. |
| MODE | Operation mode select | 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, SS/TR, MODE, PG; isolated from PGND at single-point connection to avoid ground bounce in mixed-signal systems. |
Key Features
| Feature | Design Value |
|---|---|
| iDCS-Control topology | Enables seamless PWM-to-PSM transition without output voltage glitch - critical for real-time control loops and audio subsystems. |
| Programmable soft start | Adjustable ramp time via SS/TR capacitor - prevents inrush current damage to input capacitors and upstream power sources. |
| Output voltage tracking | SS/TR pin accepts external voltage source to coordinate startup timing with master rail - essential for FPGA or ASIC core/I/O sequencing. |
| Hiccup short-circuit protection | 32-cycle fault counter followed by automatic restart - limits average power dissipation during sustained overload without latching. |
| 100% duty cycle operation | Maintains regulation down to VIN ≈ VOUT + IOUT × (RDS(on) + DCR) - supports ultra-low dropout in battery-powered applications near end-of-discharge. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6209718RWKR | Fixed 1.8-V output; same package, pinout, and control features; no external feedback divider required. | Eliminates resistor network for 1.8-V use cases; reduces BOM count and layout area but lacks adjustability. | Select when system requires only 1.8 V and design simplicity outweighs flexibility needs. |
| TPS628512RQWR | 0.5-A version in smaller SOT583 package; higher 6-V max input; includes integrated inductor option in module variants. | Lower current capacity; optimized for space-constrained IoT nodes rather than 2-A industrial loads. | Choose for battery-powered edge sensors where size and integration trump current capability. |
Compared with TPS62097RWKR, TPS6209718RWKR simplifies design for fixed 1.8-V rails but sacrifices output flexibility, while TPS628512RQWR trades current capacity and thermal performance for ultra-compact footprint - making TPS62097RWKR the optimal choice for 2-A, wide-input, adjustable POL applications demanding robust thermal and noise performance.

FAQ
What is the maximum output current supported by the TPS62097RWKR?
The TPS62097RWKR supports up to 2.0 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, adequate PCB copper area). Its high-side FET forward current limit ranges from 3.1 A to 4.2 A depending on input voltage, providing headroom for transient peaks. Thermal derating applies above 85°C ambient; full 2-A operation requires proper thermal pad soldering and ≥1-in² 2-oz copper pour per TI layout guidelines.
Does the TPS62097RWKR require external compensation components?
No, the TPS62097RWKR uses internally compensated iDCS-Control architecture and does not require external compensation components. Its design supports stable operation with output capacitors ranging from 10 µF to over 150 µF, including ceramic, polymer, and tantalum types - simplifying design and reducing bill-of-materials cost compared to externally compensated buck controllers.
How does the MODE pin configure forced PWM versus power-save mode on the TPS62097RWKR?
The MODE pin on the TPS62097RWKR determines operating mode during a 50-µs detection window after EN goes high. Connecting MODE to AGND enables automatic PWM/PSM transition; leaving it open or pulling it high via resistor selects forced PWM only. The selected resistor value (e.g., 8.2 kΩ for 1.5 MHz) also sets the fixed switching frequency - all configurations are latched at startup and cannot be changed dynamically.
Can the TPS62097RWKR be used with a 1.2-V output, and how is it configured?
Yes, the TPS62097RWKR supports 1.2-V output via external resistor divider on the FB pin. Using Equation 4 from the datasheet (VOUT = 0.8 V × (1 + R1/R2)), a 10-kΩ R1 and 20-kΩ R2 yields 1.2 V. R2 must not exceed 20 kΩ to minimize noise sensitivity. Fixed-output variants (e.g., TPS6209718) are not required - the adjustable version provides full flexibility for custom voltage rails.
What protection features are integrated into the TPS62097RWKR?
The TPS62097RWKR integrates hiccup short-circuit protection (32-cycle fault counter with auto-restart), thermal shutdown (160°C trip with 20°C hysteresis), undervoltage lockout (2.3 V nominal with 100-mV hysteresis), and output discharge (165-Ω path activated during disable/fault). These features eliminate need for external protection circuitry and ensure robust operation in harsh industrial environments without latch-up or thermal runaway.
