Product details
Overview
TPS62130RGTR from Texas Instruments is a synchronous step-down DC-DC converter optimized for high-power-density applications, delivering up to 3 A continuous output current across an input range of 3 V to 17 V, with adjustable output voltage from 0.9 V to 6 V, DCS-Control™ topology for fast transient response, and 17 µA typical quiescent current - used in POL supplies for embedded systems and solid-state drives.
For engineers reviewing the TPS62130RGTR datasheet, TPS62130RGTR pinout, TPS62130RGTR application, or TPS62130RGTR equivalent, key selection criteria include its 2.5 MHz (or 1.25 MHz) selectable switching frequency, seamless PWM-to-power-save mode transition, 100% duty cycle capability, power-good open-drain output, and thermal/short-circuit protection - all in a compact 3 mm × 3 mm QFN-16 package.
Technical Context
The TPS62130RGTR implements DCS-Control™ topology, combining direct output-voltage sensing with a fast comparator and internal compensation to achieve stable regulation, fast load-transient response, and low output ripple without external loop compensation. It supports both PWM mode (continuous conduction, fixed-frequency) and power-save mode (discontinuous conduction, variable-frequency), with automatic seamless transitions between them.
Its functional architecture includes integrated high-side (90 mΩ typ @ VIN ≥ 6 V) and low-side (40 mΩ typ @ VIN ≥ 6 V) MOSFETs, programmable soft-start/tracking via external capacitor on SS/TR, pin-selectable +5% output margining via DEF, and dual-frequency selection (FSW pin) enabling trade-offs between efficiency and solution size - all while maintaining tight DC accuracy (±1.7% initial FB voltage tolerance).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3 V to 17 V - supports single/dual Li-ion battery stacks and standard 12-V intermediate rails without external pre-regulation. |
| Output Current | Up to 3 A continuous - enables replacement of discrete buck controllers + external FETs in space-constrained POL designs. |
| Switching Frequency | 1.25 MHz or 2.5 MHz (pin-selectable) - allows optimization between inductor size (smaller at 2.5 MHz) and efficiency (higher at 1.25 MHz). |
| Quiescent Current | 17 µA typical - sustains high light-load efficiency in always-on subsystems like SSD standby or IoT sensor nodes. |
| Feedback Reference | 800 mV ±1.7% - enables precise output regulation down to 0.9 V using standard resistor dividers; supports tracking and sequencing. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without requiring external thermal monitoring. |
| Power-Good Output | Open-drain PG with 92–98% rising threshold - provides reliable rail sequencing signal for FPGA, ASIC, or multi-rail processors. |
Pinout & Package
TPS62130RGTR is housed in a thermally enhanced 16-pin VQFN package (RGT) measuring 3.00 mm × 3.00 mm with an exposed thermal pad soldered to AGND/PGND for optimal thermal performance and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (1,2,3) | Power input for high-current path | Connects directly to input capacitors and inductor; separate from AVIN to reduce noise coupling into control circuitry. |
| PG (4) | Open-drain power-good indicator | Signals valid output regulation (high-impedance when enabled & VOUT ≥ 95%; requires external pullup to ≤7 V). |
| FB (5) | Feedback input for adjustable output | Monitors resistive divider output; internal 800-mV reference enables 0.9–6 V output programming with <±1.7% accuracy. |
| AGND (6) | Analog ground reference | Must be tied directly to exposed thermal pad and system ground plane to minimize noise in feedback and control loops. |
| FSW (7) | Frequency select input | Low = ~2.5 MHz (compact design); High = ~1.25 MHz (higher efficiency); internal pulldown ensures safe default. |
| DEF (8) | Output voltage margining control | Low = nominal VOUT; High = VOUT +5%; enables hardware-based voltage margin testing without firmware changes. |
| SS/TR (9) | Soft-start and tracking input | External capacitor sets startup ramp rate; voltage injection enables synchronized ramp-up with master supply in multi-rail systems. |
| AVIN (10) | Analog supply input | Provides clean bias for control circuitry; must be connected to same source as PVIN but routed separately for noise isolation. |
| EN (13) | Enable/disable control | Active-high logic; internal 400-kΩ pulldown ensures safe shutdown if left floating; supports power-rail sequencing. |
| VOS (14) | Output voltage sense | Direct connection to output node improves regulation accuracy under dynamic load conditions by compensating for IR drop. |
| PGND (15,16) | Power ground return | Carries high-switching-current return path; must be tied to exposed thermal pad and low-impedance ground plane. |

FAQ
What is the maximum output current capability of the TPS62130RGTR?
The TPS62130RGTR delivers up to 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Peak current limit is typically 4.2 A, but sustained operation above 3 A requires careful thermal management using the exposed thermal pad and adequate copper area per TI's layout guidelines.
Does the TPS62130RGTR support output voltage tracking during power-up?
Yes, the TPS62130RGTR supports voltage tracking via its SS/TR pin. Applying a ramp voltage to this pin causes the output to follow that ramp - enabling coordinated power-up with master supplies. The device also supports monotonic start-up into pre-biased outputs, preventing reverse current flow during system initialization.
How does the DCS-Control™ topology in the TPS62130RGTR improve transient response?
The DCS-Control™ topology in the TPS62130RGTR uses direct output voltage sensing and a fast comparator to dynamically adjust switching timing, achieving sub-10-µs response to load steps. Unlike traditional voltage-mode control, it avoids phase-margin constraints and works stably with low-ESR ceramic capacitors - eliminating external compensation components.
Can the TPS62130RGTR operate with input voltage close to the output voltage?
Yes, the TPS62130RGTR supports 100% duty-cycle operation, allowing regulation when VIN approaches VOUT (e.g., 3.6 V input to 3.3 V output). In this mode, the high-side FET remains continuously on, minimizing dropout and extending usable battery voltage range - critical for Li-ion-powered devices.
What protection features are integrated into the TPS62130RGTR?
The TPS62130RGTR integrates undervoltage lockout (2.7 V threshold), thermal shutdown (160°C with 20°C hysteresis), short-circuit protection (1.6 A current limit when VOUT < 0.5 V), and overcurrent limiting (4.2 A typical). All protections are fully autonomous and require no external components to activate.
