Product details
Overview
TPS62140ARGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications. It delivers up to 2 A continuous output current, supports 3 V to 17 V input range, regulates adjustable output voltage from 0.9 V to 6 V, and features DCS-Control™ topology for fast transient response in POL and battery-powered systems.
For engineers reviewing the TPS62140ARGTR datasheet, TPS62140ARGTR pinout, TPS62140ARGTR application, or TPS62140ARGTR equivalent, key selection considerations include its 2.5 MHz (typ.) switching frequency, 17 µA quiescent current in power-save mode, pin-selectable +5% output margining, seamless PWM-to-Power-Save transition, and integrated power-good signaling with open-drain output.
Technical Context
The TPS62140ARGTR implements DCS-Control™-a hybrid regulation topology combining direct output-voltage sensing with an internal ac comparator and voltage feedback loop. It operates in PWM mode at 2.5 MHz (FSW = low) or 1.25 MHz (FSW = high), enabling small external inductors and stable regulation across wide VIN–VOUT differentials.
Its functional architecture includes integrated high-side (90 mΩ typ. @ VIN ≥ 6 V) and low-side MOSFETs, programmable soft-start via external capacitor on SS/TR, tracking capability, 100% duty-cycle operation for ultra-low dropout, and thermal shutdown at 160°C with 20°C hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62141ARGTR | Fixed 1.8 V output; identical pinout, package, and feature set except FB and DEF pins unused | No external feedback divider needed; simplified BOM for fixed-voltage designs | Select when 1.8 V output is required and board space/layout optimization is critical |
| TPS62130ARGTR | Lower 3–6 V input range; 1.5 A max output; same DCS-Control™, package, and pin compatibility | Not suitable for 12-V rail or wide-VIN battery inputs; limited headroom for 100% duty-cycle operation | Choose only for cost-sensitive, lower-power applications where input voltage never exceeds 6 V |
Compared with TPS62141ARGTR, the TPS62140ARGTR offers full output adjustability but requires two external resistors; compared with TPS62130ARGTR, it provides higher input voltage tolerance and output current, making it suitable for broader industrial and computing applications without redesign.

FAQ
What is the maximum output current supported by the TPS62140ARGTR?
The TPS62140ARGTR supports up to 2 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, proper thermal layout). Peak current capability depends on input-output differential, ambient temperature, and PCB copper area. The device includes internal current limiting (2.45–3.5 A typical) and thermal shutdown (160°C) to prevent damage during overload.
Does the TPS62140ARGTR support pre-biased start-up?
Yes, the TPS62140ARGTR supports monotonic pre-biased start-up. When enabled, both internal MOSFETs remain off until the internal soft-start ramp exceeds the pre-existing output voltage. During this phase, the current limit is reduced to ~1.6 A to prevent reverse current flow and ensure controlled voltage rise without overshoot or instability.
How does the DCS-Control™ topology in the TPS62140ARGTR improve transient response?
The DCS-Control™ topology in the TPS62140ARGTR uses a fast ac comparator directly sensing output voltage changes, enabling sub-10 µs response to load transients. Combined with a stable dc feedback loop, it maintains regulation across wide load ranges without external compensation components-delivering superior dynamic performance versus conventional voltage-mode or current-mode controllers.
Can the TPS62140ARGTR operate with input voltage close to the output voltage?
Yes, the TPS62140ARGTR supports 100% duty-cycle operation, allowing regulation when VIN approaches VOUT. In this mode, the high-side MOSFET remains continuously on while the low-side FET is disabled. Minimum input voltage for regulation depends on load current, RDS(on)_HS, and inductor DCR, per equation: VIN(min) = VOUT + IOUT × (RDS(on)_HS + R_L).
What is the function of the VOS pin on the TPS62140ARGTR?
On the TPS62140ARGTR, the VOS (Voltage Output Sense) pin provides a dedicated connection point for remote sensing of the output voltage. Routing VOS directly to the load improves load regulation accuracy by compensating for IR drop across PCB traces or connectors-critical for high-current or precision applications where output voltage stability must be maintained within ±1%.
