Product details
Overview
TPS62001DGSRG4 from Texas Instruments is a fixed-output, synchronous step-down DC-DC converter delivering 1 V at up to 600 mA from a 2–5.5 V input, featuring 95% peak efficiency, 50 μA quiescent current in power-save mode, and internal soft-start. It serves as the primary voltage regulator for low-power microcontrollers in battery-powered handheld devices.
For engineers reviewing the TPS62001DGSRG4 datasheet, TPS62001DGSRG4 pinout, TPS62001DGSRG4 application, or TPS62001DGSRG4 equivalent, key selection criteria include its 1-V fixed output, pin-programmable 600/1200-mA current limit, SYNC-controlled PFM/PWM mode switching, and VSSOP-10 package compatibility with space-constrained portable designs.
Technical Context
The TPS62001DGSRG4 implements a current-mode PFM/PWM control architecture with automatic mode transition: it operates in fixed-frequency PWM (750 kHz typical) under moderate-to-heavy loads and switches to variable-frequency PFM at light loads to maintain high efficiency. Its internal compensation eliminates external loop components.
It integrates complementary P-channel and N-channel MOSFETs, supports 100% duty-cycle operation for ultra-low dropout, and includes undervoltage lockout (1.6 V typ), open-drain power-good (PG) with 92% threshold, and antiringing switch functionality-enabled only in fixed-output variants like the TPS62001DGSRG4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1 V ±3% over load and line; enables direct powering of 1-V core logic without external feedback resistors. |
| Input Voltage Range | 2 V to 5.5 V; supports single-cell Li-ion (2.7–4.2 V), 2–3-cell alkaline/NiMH, and USB-powered systems. |
| Max Output Current | 600 mA (ILIM = GND); sufficient for low-power DSPs and ARM Cortex-M0/M3 cores in active mode. |
| Quiescent Current | 50 μA typical in PFM mode; extends battery life in standby/sleep states of portable electronics. |
| Switching Frequency | 750 kHz typical (500–1000 kHz sync-capable); allows use of compact 10-μH inductors and low-ESR ceramic capacitors. |
| Efficiency | 95% peak at 3.6 VIN/2.5 VOUT/200 mA; reduces thermal load and improves runtime in thermally constrained enclosures. |
| Power-Good Threshold | 92% of nominal output (0.92 V); provides reliable system reset signaling before processor initialization. |
Pinout & Package
TPS62001DGSRG4 is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for high-density PCB layouts in portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input power supply | Accepts 2–5.5 V; requires 10-μF input capacitor for stable operation and EMI suppression. |
| FC (Pin 2) | Input bypass | High-frequency decoupling node; must be connected to 0.1-μF capacitor near the pin to stabilize internal bias circuitry. |
| GND (Pin 3) | Analog ground reference | Reference for FB, EN, ILIM, SYNC; separate from PGND to minimize noise coupling into feedback path. |
| PG (Pin 4) | Open-drain power-good indicator | Signals valid regulation after 100 μs delay; requires external pull-up to VOUT for system monitoring. |
| FB (Pin 5) | Feedback input | Internally connected to 1-V divider; unused in fixed-output TPS62001DGSRG4-leave unconnected. |
| ILIM (Pin 6) | Current-limit configuration | Grounded to set 600-mA switch limit; tied to VIN for 1200-mA limit-determines inductor saturation margin. |
| SYNC (Pin 7) | Mode control and synchronization | Low = PFM/PWM auto-switching; High = forced PWM; accepts 500–1000 kHz CMOS clock for EMI reduction. |
| EN (Pin 8) | Enable control | Active-high logic input; pulls device into <1-μA shutdown when low-enables system-level power sequencing. |
| L (Pin 9) | Switch node | Connects to inductor; carries high di/dt switching current-requires short, low-inductance trace to minimize ringing. |
| PGND (Pin 10) | Power ground return | Return path for high-current switch and inductor; must be joined to GND at single point near IC for clean layout. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P- and N-channel MOSFETs eliminate external diode, reducing conduction loss and improving efficiency by >10% vs. asynchronous designs. |
| Antiringing switch | Active in fixed-output versions only; suppresses parasitic LC oscillation during DCM, lowering radiated EMI without external snubbers. |
| Internal soft-start | 1-ms typical ramp time prevents output overshoot and inrush current-eliminates need for external soft-start circuitry. |
| 100% duty-cycle operation | Enables dropout as low as RDS(on) × IOUT; maintains regulation even when VIN drops within ~100 mV of VOUT. |
| Pin-programmable current limit | Dual thresholds (600/1200 mA) selected via ILIM connection-allows one BOM to support multiple inductor ratings and load profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62000DGSR | Adjustable output (0.8–VIN) vs. fixed 1 V; same package, pinout, and control features. | Requires external resistor divider and feedforward capacitor; suited for multi-rail or configurable systems. | Select TPS62000DGSR only if output voltage flexibility is required-adds BOM cost and layout complexity. |
| TPS62040DGQR | Higher 2-A output, 3-MHz switching, smaller 2-mm × 2-mm WSON package; different pinout and control interface. | Targets higher-performance processors; lacks SYNC pin and PG output-no system monitoring or EMI synchronization. | Choose TPS62040DGQR for >600-mA loads or space-constrained designs where PG and SYNC are non-critical. |
Compared with TPS62000DGSR and TPS62040DGQR, the TPS62001DGSRG4 offers optimal balance of fixed 1-V simplicity, integrated PG monitoring, SYNC-enabled EMI control, and proven 600-mA capability in legacy portable designs-making it ideal for cost-sensitive, volume production of battery-powered 1-V core supplies.

FAQ
What is the output voltage tolerance of the TPS62001DGSRG4 over temperature and load?
The TPS62001DGSRG4 delivers a fixed 1-V output with ±3% tolerance across the full operating range: –40°C to 85°C ambient temperature, 10 mA to 600 mA load, and 2.5 V to 5.5 V input voltage. This specification is verified per TI's SLVS294F datasheet Section 7.5, ensuring consistent core voltage delivery for sensitive digital logic without external trimming.
Can the TPS62001DGSRG4 be synchronized to an external clock, and what is the supported frequency range?
Yes, the TPS62001DGSRG4 supports external synchronization via its SYNC pin, accepting CMOS-level clock signals from 500 kHz to 1000 kHz. When synchronized, it disables power-save mode and operates in forced PWM-enabling precise EMI frequency placement and deterministic switching behavior critical for USB and RF-sensitive applications.
How does the current limit setting work on the TPS62001DGSRG4, and what are the two thresholds?
The TPS62001DGSRG4 uses the ILIM pin to select between two switch current limits: connecting ILIM to GND sets the limit to 600 mA (typical), while connecting it to VIN raises it to 1200 mA (typical). This dual-threshold design allows one footprint to accommodate different inductor saturation ratings and peak load requirements without changing the IC.
Does the TPS62001DGSRG4 include an antiringing switch, and is it active in this variant?
Yes-the TPS62001DGSRG4 includes an integrated antiringing switch, and it is enabled because this is a fixed-output variant (per datasheet Section 8.3.1). The feature suppresses parasitic oscillations during discontinuous conduction mode, reducing radiated EMI without requiring external snubber components.
What is the purpose and behavior of the PG (power-good) pin on the TPS62001DGSRG4?
The PG pin on the TPS62001DGSRG4 is an open-drain output that goes high when the output voltage exceeds 92% of nominal (0.92 V), indicating valid regulation. It remains inactive for the first 100 μs after enable and requires an external pull-up to VOUT. This signal enables safe processor reset sequencing and system-level power monitoring in portable designs.
