Product details
Overview
TPS62007DGSRG4 from Texas Instruments is a synchronous step-down DC-DC converter optimized for low-power portable systems, delivering up to 600 mA output current with 95% peak efficiency at 3.6 V input and 2.5 V output, featuring adjustable output voltage (0.8 V to VIN), 750 kHz typical switching frequency, and pin-programmable current limit (600 mA or 1.2 A).
For engineers reviewing the TPS62007DGSRG4 datasheet, TPS62007DGSRG4 pinout, TPS62007DGSRG4 application, or TPS62007DGSRG4 equivalent, key selection criteria include its 2–5.5 V input range, 50 μA quiescent current in power-save mode, 10-pin VSSOP package, PFM/PWM hybrid control, and support for external clock synchronization up to 1 MHz.
Technical Context
The TPS62007DGSRG4 implements a current-mode PFM/PWM control architecture: it operates in fixed-frequency PWM mode under moderate-to-heavy loads (≥120 mA) and transitions to variable-frequency PFM mode at light loads to maintain high efficiency, with internal slope compensation and soft-start (1 ms typical). It integrates both P-channel and N-channel MOSFETs for synchronous rectification.
Its functional modes are determined by the SYNC pin: grounded for automatic PFM/PWM transition, tied to VIN for forced PWM (fixed 750 kHz), or driven by an external CMOS clock (500–1000 kHz); ILIM selects current limit (GND = 600 mA typ., VIN = 1.2 A typ.), and EN enables/disables with <1 μA shutdown current.
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 2–3-cell alkaline/NiMH battery inputs without external regulation. |
| Output Voltage | Fixed 3.3 V - eliminates need for external feedback resistors; regulated within ±3% over load and line variations. |
| Max Output Current | 600 mA - achievable with 10 μH inductor and proper thermal layout; limited to 200 mA under 2 V input (2-cell NiMH). |
| Quiescent Current | 50 μA (typ.) - enables >1000-hour battery life in always-on standby applications with light-load operation. |
| Switching Frequency | 750 kHz (typ.) - allows compact 10 μH inductors and 10 μF ceramic output capacitors (for VOUT ≥1.8 V). |
| Efficiency Peak | 95% - measured at VIN = 3.6 V, VOUT = 2.5 V, IOUT = 200 mA; maintains >85% down to 1 mA load in PFM mode. |
| Power Good Threshold | 92% of nominal VOUT - open-drain PG signal asserts after 100 μs startup delay; requires external pull-up to VOUT. |
Pinout & Package
TPS62007DGSRG4 is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, with exposed thermal pad (PGND-connected) for enhanced thermal performance in space-constrained PCB 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 close to pin for stable high-frequency operation. |
| FC (Pin 2) | Input filter bypass | Connects 0.1 μF ceramic capacitor to reduce high-frequency noise on VIN rail before internal regulator stages. |
| GND (Pin 3) | Analog ground reference | Provides reference for error amplifier and internal bias circuits; must be separated from PGND in sensitive analog sections. |
| PG (Pin 4) | Power-good indicator | Open-drain output active high when VOUT ≥92% of 3.3 V; requires external pull-up resistor to VOUT for system sequencing. |
| FB (Pin 5) | Feedback input | Internally connected to fixed 3.3 V divider; unused in TPS62007 - leave unconnected or tie to GND per TI recommendation. |
| ILIM (Pin 6) | Current limit select | Tied to GND for 600 mA switch current limit (typ.); tied to VIN for 1.2 A limit - sets peak inductor current threshold. |
| SYNC (Pin 7) | Mode control input | GND = auto PFM/PWM; VIN = forced PWM; external 500–1000 kHz CMOS clock = synchronized operation. |
| EN (Pin 8) | Enable control | Logic high (≥1.3 V) enables converter; logic low (<0.4 V) disables with <1 μA shutdown current. |
| L (Pin 9) | Switch node | Connects to inductor; carries high di/dt switching current - requires short, wide trace and adjacent PGND pour. |
| PGND (Pin 10) | Power ground return | Low-impedance return path for inductor current and internal FETs; must be connected directly to thermal pad and bulk output capacitor ground. |
Key Features
| Feature | Design Value |
|---|---|
| PFM/PWM Hybrid Control | Maintains >85% efficiency from 1 mA to 600 mA load by automatically switching between fixed-frequency PWM and variable-frequency PFM modes. |
| 100% Duty Cycle Operation | Enables dropout as low as 100 mV at full load by holding high-side P-FET fully on when VIN approaches VOUT, critical for battery end-of-life operation. |
| Integrated Antiringing Switch | Reduces EMI in DCM by clamping inductor flyback energy - active only in fixed-output variants like TPS62007, not adjustable versions. |
| Internal Soft-Start | 1 ms typical ramp prevents output overshoot and inrush current during enable, eliminating need for external soft-start circuitry. |
| Undervoltage Lockout (UVLO) | Disables operation below ~1.6 V VIN to prevent erratic behavior and ensure clean startup from weak batteries. |

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 |
|---|---|---|---|
| TPS62006DGSR | Fixed 2.5 V output; identical pinout, package, and control features; same 600 mA rating and 50 μA IQ. | Requires redesign of output filtering and load interface if system needs 2.5 V instead of 3.3 V. | Select when target application requires 2.5 V logic rail and shares identical board layout constraints. |
| TPS62231DRVR | Higher 3 MHz switching frequency; smaller 2.0 × 2.0 mm WSON package; 400 mA max output; 17 μA IQ. | Better suited for ultra-compact designs with tight EMI requirements but lower current capability. | Choose for space-constrained, high-density layouts where 400 mA suffices and higher frequency simplifies filtering. |
Compared with TPS62007DGSRG4, TPS62006DGSR offers identical form-factor and performance at 2.5 V, while TPS62231DRVR trades current capacity and package size for higher frequency and lower quiescent current - making each optimal for distinct voltage, size, and efficiency priorities.

FAQ
What is the output voltage configuration of the TPS62007DGSRG4?
The TPS62007DGSRG4 provides a fixed 3.3 V output voltage. Unlike the adjustable TPS62000 variant, it uses an internal resistor divider - the FB pin is not used for external programming and should be left unconnected or tied to GND per TI's design recommendations. This eliminates external feedback components and simplifies layout for dedicated 3.3 V rail generation.
How does the TPS62007DGSRG4 manage efficiency at light loads?
The TPS62007DGSRG4 maintains high efficiency at light loads through automatic transition to pulse-frequency modulation (PFM) mode when output current drops below ~120 mA for more than 15 switching cycles. In this mode, it reduces switching frequency and holds peak inductor current constant, achieving 50 μA typical quiescent current and sustaining >85% efficiency down to 1 mA load - critical for battery longevity in standby operation.
Can the TPS62007DGSRG4 be synchronized to an external clock?
Yes, the TPS62007DGSRG4 supports external clock synchronization via the SYNC pin, accepting CMOS-level signals from 500 kHz to 1000 kHz. When synchronized, the device disables PFM mode and operates strictly in forced PWM mode, enabling precise EMI frequency placement and simplified filtering in noise-sensitive applications such as audio or RF subsystems.
What thermal considerations apply to the TPS62007DGSRG4 in continuous 600 mA operation?
In continuous 600 mA operation at 3.6 V input and 3.3 V output, the TPS62007DGSRG4 dissipates approximately 180 mW. With its 160°C/W junction-to-ambient thermal resistance (RθJA) in the VSSOP package, proper PCB layout - including a solid PGND thermal pad connection and ≥2 cm² copper pour - is essential to keep junction temperature below 125°C. Derating is recommended above 60°C ambient.
Is the TPS62007DGSRG4 RoHS-compliant and lead-free?
Yes, the TPS62007DGSRG4 is RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 2a (MSL-2a) and qualified for reflow soldering per IPC/JEDEC J-STD-020. The "G4" suffix in the part number explicitly denotes green (halogen-free) and lead-free packaging per TI's standard environmental compliance program.
