Product details
Overview
TPS62007DGS from Texas Instruments is a synchronous step-down DC-DC converter optimized for low-power portable systems, delivering fixed 3.3 V output at up to 600 mA from 2 V–5.5 V input. It features 750 kHz typical switching frequency, 50 μA quiescent current in power-save mode, and pin-programmable current limit (600 mA or 1.2 A). Used in USB-based DSL modems and network interface cards requiring stable, low-noise regulation.
For engineers reviewing the TPS62007DGS datasheet, TPS62007DGS pinout, TPS62007DGS application, or TPS62007DGS equivalent, key selection criteria include its fixed 3.3 V output, VSSOP-10 (DGS) package, PFM/PWM hybrid operation, 95% peak efficiency at 200 mA, and support for external clock synchronization up to 1 MHz.
Technical Context
The TPS62007DGS implements current-mode control with internal slope compensation and automatic transition between PWM (fixed 750 kHz) and PFM (variable frequency, ~150 mA peak inductor current threshold) based on load. Its synchronous rectification uses integrated P-channel high-side and N-channel low-side MOSFETs with typical RDS(on) of 280 mΩ and 410 mΩ respectively at 3.6 V.
It supports three functional modes via the SYNC pin: GND enables PFM/PWM auto-switching; VIN forces continuous PWM; no signal defaults to internal 750 kHz oscillator. The device includes undervoltage lockout (~1.6 V), soft-start (~1 ms), 100% duty-cycle dropout operation, and open-drain power-good (PG) with 92% VOUT threshold and 2.5% hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±4% over 10 mA–600 mA load and 3.6 V–5.5 V input; enables direct replacement of LDOs in 3.3 V rail applications. |
| Input Voltage Range | 2 V to 5.5 V; supports single-cell Li-ion (2.7–4.2 V), two/three-cell alkaline/NiMH, and USB 5 V supply without external regulators. |
| Max Output Current | 600 mA at VIN ≥3.6 V; sufficient for powering baseband processors, USB PHYs, and low-power FPGAs in portable designs. |
| Quiescent Current | 50 μA typical in PFM mode; extends battery life in always-on subsystems such as modem standby or sensor wake-up circuits. |
| Switching Frequency | 750 kHz typical (500–1000 kHz range); allows use of compact 10 μH inductors and reduces EMI filtering burden vs lower-frequency converters. |
| Efficiency | 95% peak at 3.6 VIN/2.5 VOUT/200 mA; maintains >85% down to 10 mA load due to PFM mode, critical for dynamic power scaling. |
| Power-Good Threshold | 92% of nominal VOUT (3.04 V for 3.3 V); provides reliable system reset signaling after regulated output stabilizes, with 100 μs delay post-enable. |
Pinout & Package
TPS62007DGS is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm with 0.5 mm pitch, optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Main power input | Accepts 2–5.5 V; requires 10 μF ceramic bypass capacitor close to pin for stable high-frequency decoupling. |
| FC (Pin 2) | Input supply filter | High-frequency bypass node; must connect 0.1 μF capacitor to GND to suppress switching noise on input rail. |
| GND (Pin 3) | Analog ground reference | Signal return for error amplifier and reference; separate from PGND to minimize noise coupling into feedback path. |
| PG (Pin 4) | Open-drain status output | Asserts high when VOUT ≥3.04 V; requires external pull-up to VOUT or system rail for valid logic-level indication. |
| FB (Pin 5) | Feedback input | Internally connected to fixed 3.3 V divider; not used externally-bypassed per datasheet for TPS62007 variant. |
| ILIM (Pin 6) | Current limit select | Ground = 600 mA limit; connect to VIN = 1.2 A limit-configures overcurrent protection threshold before thermal shutdown. |
| SYNC (Pin 7) | Mode control input | GND = PFM/PWM auto-switching; VIN = forced PWM; floating = internal 750 kHz oscillator-enables dynamic noise/power trade-off. |
| EN (Pin 8) | Enable control | Logic high ≥1.3 V enables regulation; low ≤0.4 V shuts down device drawing <1 μA-supports system-level power sequencing. |
| L (Pin 9) | Power switch node | Connects to 10 μH inductor; carries high di/dt switching current-requires short, wide trace and solid PGND plane beneath. |
| PGND (Pin 10) | Power ground return | High-current return path for internal MOSFETs and inductor; must be tied to GND at single point near IC to prevent ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P- and N-channel MOSFETs eliminate external diode, reducing conduction loss and enabling >95% efficiency at medium loads. |
| PFM/PWM hybrid operation | Automatically switches to pulse-frequency modulation below ~120 mA load, maintaining >85% efficiency down to 10 mA while minimizing quiescent current. |
| 100% duty-cycle dropout | Enables regulation even when VIN drops within ~100 mV of VOUT (3.3 V), extending usable battery voltage range in Li-ion applications. |
| Pin-programmable current limit | Two selectable limits (600 mA / 1.2 A) via ILIM pin connection-allows one BOM to support varying load requirements across product variants. |
| Internal soft-start | ~1 ms voltage ramp prevents output overshoot and inrush current during power-up, eliminating need for external soft-start circuitry. |

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 |
|---|---|---|---|
| TPS62006DGS | Fixed 3.3 V output, identical pinout and electrical specs; differs only in factory-trimmed feedback network for same nominal voltage. | No functional difference-both rated for 600 mA, same thermal performance, and identical feature set including SYNC/EN/PG/ILIM. | Select TPS62006DGS if sourcing from alternate TI lot or distributor inventory; electrically interchangeable with TPS62007DGS in all designs. |
| TPS62231DRVR | 3 MHz switching frequency, 300 mA max output, 17 μA quiescent current, 2-mm × 2-mm WSON package-smaller footprint but lower current capability. | Better suited for ultra-low-power microcontroller rails where size and IQ dominate; insufficient for 600 mA modem or PDA loads. | Choose TPS62231DRVR only for space-critical, sub-300 mA applications; TPS62007DGS remains optimal for full 600 mA requirement with proven thermal margin in VSSOP. |
Compared with TPS62006DGS, TPS62007DGS offers identical functionality and drop-in compatibility; versus TPS62231DRVR, it delivers double the output current and higher thermal robustness in a slightly larger package-making it the preferred choice for 3.3 V/600 mA system rails demanding reliability and design continuity.

FAQ
What is the output voltage tolerance of the TPS62007DGS under full load?
The TPS62007DGS delivers a fixed 3.3 V output with ±4% tolerance across 10 mA to 600 mA load current and 3.6 V to 5.5 V input voltage, as specified in the electrical characteristics table. This ensures reliable operation of 3.3 V digital logic and interface circuits without additional post-regulation.
Can the TPS62007DGS operate from a single 1.5 V alkaline cell?
No, the TPS62007DGS requires a minimum 2 V input voltage per its recommended operating conditions. A single 1.5 V alkaline cell falls below this threshold; however, two series alkaline cells (3.0 V nominal) fully satisfy the 2–5.5 V input range and are commonly used in handheld devices powered by this IC.
How does the SYNC pin affect efficiency and noise performance of the TPS62007DGS?
When SYNC is grounded, the TPS62007DGS operates in PFM/PWM auto-switching mode, maximizing light-load efficiency (>85% at 10 mA) but generating variable-frequency noise. When SYNC is tied to VIN, it forces fixed-frequency PWM operation-reducing EMI predictability for filtering but lowering efficiency at light loads due to constant switching losses.
What is the purpose of the FC pin on the TPS62007DGS and how should it be connected?
FC is the high-frequency input bypass pin. It must be connected to a 0.1 μF ceramic capacitor placed as close as possible to the pin and routed to GND. This capacitor filters switching noise on the input rail, preventing instability and ensuring clean gate drive for the internal MOSFETs-omitting it risks erratic regulation or oscillation.
Does the TPS62007DGS require external compensation components for stability?
No, the TPS62007DGS features internally compensated control loop architecture. No external compensation network is needed-only the required input/output capacitors (10 μF each for VOUT ≥1.8 V), 10 μH inductor, and FC bypass capacitor are mandatory per the typical application schematic.
