Product details
Overview
TPS62000DGSRG4 from Texas Instruments is an adjustable-output, synchronous step-down DC-DC converter optimized for low-power portable systems. It operates from 2 V to 5.5 V input, delivers up to 600 mA output current, achieves >95% peak efficiency at 3.6 VIN/2.5 VOUT, and features pin-selectable current limit (600 mA or 1.2 A) - enabling use in battery-powered microcontroller cores requiring stable 0.8–VIN regulation.
For engineers reviewing the TPS62000DGSRG4 datasheet, TPS62000DGSRG4 pinout, TPS62000DGSRG4 application, or TPS62000DGSRG4 equivalent, key selection criteria include its PFM/PWM hybrid control mode, 750 kHz nominal switching frequency, 50 μA quiescent current in power-save mode, 100% duty-cycle capability for ultra-low dropout, and VSSOP-10 package compatibility with space-constrained handheld PCB layouts.
Technical Context
The TPS62000DGSRG4 implements a current-mode synchronous buck topology with integrated P-channel high-side and N-channel low-side MOSFETs. Its control loop uses internal compensation and a 0.45 V reference voltage, supporting external feedback via FB pin for adjustable output (0.8 V to VIN). The device transitions between fixed-frequency PWM (750 kHz) and variable-frequency PFM based on load - entering PFM when peak inductor current falls below ~120 mA for ≥15 cycles.
Functional modes are managed through dedicated pins: SYNC selects forced PWM (SYNC = VIN), power-save (SYNC = GND), or external clock synchronization (500–1000 kHz); ILIM sets current limit (GND = 600 mA typ., VIN = 1.2 A typ.); EN enables shutdown (<1 μA IQ). Soft-start (≈1 ms) prevents output overshoot, and antiringing operation is disabled for the adjustable TPS62000 variant per datasheet Section 8.3.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V) and dual/triple alkaline/NiMH batteries without external LDO pre-regulation. |
| Output Voltage Range | 0.8 V to VIN - adjustable via external resistor divider on FB pin; enables precise core voltage scaling for low-voltage MCUs/DSPs. |
| Max Output Current | 600 mA - achievable with 10 μH inductor and proper thermal layout; limited by internal MOSFET RDS(on) and thermal resistance (RθJA = 160 °C/W). |
| Quiescent Current | 50 μA (typ.) in PFM mode - minimizes battery drain during standby in always-on sensor nodes or sleep-mode peripherals. |
| Switching Frequency | 750 kHz (nominal) - enables compact 10 μH inductors and 10 μF/47 μF ceramic output capacitors depending on VOUT. |
| Efficiency Peak | 95% at 3.6 VIN/2.5 VOUT/200 mA - achieved via synchronous rectification and low-RDS(on) MOSFETs (200–410 mΩ P-ch, 200–500 mΩ N-ch). |
| Power Good Threshold | 92% of nominal VOUT - open-drain PG signal asserts after 100 μs delay, enabling safe system power sequencing in multi-rail designs. |
Pinout & Package
The TPS62000DGSRG4 is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, with exposed thermal pad for enhanced heat dissipation in compact portable layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Main power input | Accepts 2–5.5 V supply; requires 10 μF ceramic bypass capacitor (CIN) placed adjacent to FC pin. |
| FC (Pin 2) | Input supply bypass | High-frequency decoupling node; must connect 0.1 μF capacitor directly to VIN for stable switching noise suppression. |
| GND (Pin 3) | Analog ground reference | Reference for error amplifier and internal bias circuits; separate from PGND to minimize noise coupling into feedback path. |
| PG (Pin 4) | Power good indicator | Open-drain output asserting high when VOUT ≥92% nominal; requires external pull-up to VOUT for valid sequencing signal. |
| FB (Pin 5) | Feedback input | Connects to external resistor divider (R1/R2 ≤1 MΩ) to set adjustable output; internal divider disabled for TPS62000. |
| ILIM (Pin 6) | Current limit select | Ground = 600 mA switch limit (typ.), VIN = 1.2 A limit (typ.); determines maximum inductor peak current and short-circuit robustness. |
| SYNC (Pin 7) | Mode control input | GND = PFM/PWM auto-switching; VIN = forced PWM; external CMOS clock (500–1000 kHz) enables EMI reduction via synchronization. |
| EN (Pin 8) | Enable control | Logic high enables regulation; logic low reduces supply current to <1 μA, supporting deep-sleep states in battery-powered systems. |
| L (Pin 9) | Switch node | Drain connection of internal P-ch and N-ch MOSFETs; routes to external 10 μH inductor; critical for EMI layout and thermal management. |
| PGND (Pin 10) | Power ground return | Low-impedance return path for inductor current and switch node; must be connected separately from analog GND and tied near L pin. |
Key Features
| Feature | Design Value |
|---|---|
| PFM/PWM Hybrid Control | Maintains >85% efficiency down to 1 mA load via automatic mode switching - eliminates need for external enable/disable sequencing in dynamic power states. |
| 100% Duty-Cycle Operation | Enables dropout as low as RDS(on) × IOUT - supports VOUT regulation even when VIN drops within ~100 mV of target, critical for end-of-battery-life operation. |
| Internal Soft-Start | ≈1 ms ramp time prevents inrush current and output overshoot during wake-up - removes need for external soft-start circuitry in MCU reset timing chains. |
| Pin-Programmable Current Limit | Two discrete limits (600 mA / 1.2 A) selected by ILIM tie-off - allows one BOM to support both low-power sensor and higher-current peripheral variants. |
| Thermal Protection | Junction temperature shutdown at 150 °C (absolute max) with hysteresis - protects against sustained overload or poor PCB heatsinking without external thermal sensors. |

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 |
|---|---|---|---|
| TPS62007DGS | Fixed 3.3 V output; no FB pin or external divider required; identical package and pinout. | Eliminates resistor network but lacks voltage adjustability - suitable only for static 3.3 V rails like I/O or memory interfaces. | Select TPS62007DGS when output voltage is fixed and board space for feedback resistors is constrained. |
| TPS62231DRVR | Higher 3 MHz switching frequency; 300 mA output; smaller 6-pin WSON package; lower 17 μA quiescent current. | Better suited for ultra-compact, low-IQ applications (e.g., wearables), but insufficient current for 600 mA MCU cores. | Choose TPS62231DRVR only for sub-300 mA loads where minimal footprint and lowest standby current are prioritized over output flexibility. |

FAQ
What is the minimum input voltage required for TPS62000DGSRG4 to regulate output?
The TPS62000DGSRG4 specifies a minimum operating input voltage of 2 V. However, practical regulation requires VIN ≥ VOUT + (IOUT × RDS(on)), where RDS(on) is ~200–410 mΩ for the P-channel MOSFET. For example, at 600 mA and 1.2 V output, VIN must exceed ~1.32 V to sustain regulation - but the device will not start up below 2 V due to undervoltage lockout (UVLO threshold ≈1.6 V typical). Thus, reliable operation begins at 2 V.
Can TPS62000DGSRG4 operate with a 10 μH inductor and 10 μF output capacitor at 1.8 V output?
Yes - the TPS62000DGSRG4 datasheet explicitly specifies COUT = 10 μF for VOUT ≥1.8 V. A 10 μH inductor is the recommended minimum value for stable operation across the full load range. At 1.8 V output, the device maintains >90% efficiency at 300 mA with this combination, and the internal compensation ensures stability without additional external components beyond the standard FB divider and input/output capacitors.
How does the SYNC pin affect efficiency and noise performance in TPS62000DGSRG4?
When SYNC = GND, TPS62000DGSRG4 operates in PFM/PWM auto-switching mode, maximizing light-load efficiency (50 μA IQ) but generating variable-frequency noise. When SYNC = VIN, it forces fixed-frequency PWM mode - reducing EMI predictability and simplifying filtering, though quiescent current rises to ~75 μA and light-load efficiency decreases. External clock sync (500–1000 kHz) retains PWM benefits while aligning switching noise to non-sensitive bands.
Is the antiringing switch active in TPS62000DGSRG4?
No - the antiringing switch is explicitly disabled for the adjustable-output TPS62000DGSRG4 per TI datasheet Section 8.3.1. It is only enabled in fixed-output variants (e.g., TPS62008DGS). Therefore, TPS62000DGSRG4 relies solely on the load comparator to prevent reverse inductor current in DCM, without the additional EMI suppression provided by the antiringing switch.
What is the purpose of the FC pin on TPS62000DGSRG4, and how should it be decoupled?
The FC (Filter Capacitor) pin on TPS62000DGSRG4 is a dedicated high-frequency input bypass node that must be connected to a 0.1 μF ceramic capacitor placed as close as possible to the pin and referenced to VIN. This capacitor filters switching noise injected back into the input supply, ensuring stable operation and preventing interference with upstream regulators or shared battery rails - omitting or misplacing this capacitor risks oscillation or degraded efficiency.
