Product details
Overview
TPS62007DGSR 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. It operates from 2 V to 5.5 V input, supports adjustable or fixed 3.3 V output, and features pin-programmable current limit (600 mA/1.2 A) and external clock synchronization up to 1 MHz.
For engineers reviewing the TPS62007DGSR datasheet, TPS62007DGSR pinout, TPS62007DGSR application, or TPS62007DGSR equivalent, key selection considerations include its 750 kHz typical switching frequency, 50 µA quiescent current in power-save mode, 10-pin VSSOP (DGS) package, and PFM/PWM hybrid control architecture for wide-load-efficiency optimization.
Technical Context
The TPS62007DGSR implements current-mode control with internal slope compensation and a dual-MOSFET synchronous rectifier (P-channel high-side, N-channel low-side). Its PFM/PWM transition occurs automatically at ~120 mA load threshold, maintaining >85% efficiency down to 1 mA while suppressing reverse inductor current via antiringing logic in fixed-output variants.
It integrates undervoltage lockout (~1.6 V), soft-start (~1 ms ramp), 100% duty-cycle dropout operation, and a precision 0.45 V internal reference. The SYNC pin enables forced PWM (low-noise, fixed-frequency) or power-save mode (variable-frequency, minimal quiescent current), with seamless mode switching during operation.
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 without pre-regulation |
| Output Voltage | Fixed 3.3 V ±3% - stable regulation across 10 mA–600 mA load with <0.6% load regulation |
| Max Output Current | 600 mA - achievable with ILIM tied to GND; 1.2 A option available when ILIM tied to VIN |
| Quiescent Current | 50 µA (typ) - enables >1000-hour battery life in always-on sensor nodes at light load |
| Switching Frequency | 750 kHz (typ), 500–1000 kHz sync range - permits use of compact 10 µH inductors and low-ESR ceramic capacitors |
| Efficiency | 95% (peak at 200 mA, 3.6 V→2.5 V) - reduces thermal stress and extends runtime in space-constrained handhelds |
| Package | VSSOP-10 (DGS), 3.0 mm × 3.0 mm - surface-mount compatible with automated assembly and high-density PCB layouts |
Pinout & Package
VSSOP-10 (DGS) package: 3.00 mm × 3.00 mm body, 0.5 mm lead pitch, exposed thermal pad (PGND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power input | Accepts 2–5.5 V supply; requires 10 µF input capacitor for stability and ripple suppression |
| FC (Pin 2) | Input bypass | High-frequency decoupling node; must connect 0.1 µF capacitor close to pin for EMI reduction |
| GND (Pin 3) | Analog ground | Reference for feedback and control circuits; separate from PGND to minimize noise coupling |
| PG (Pin 4) | Power-good open-drain | Signals valid output (>92% nominal) after 100 µs startup delay; requires external pull-up to VOUT |
| FB (Pin 5) | Feedback input | Monitors output via internal 0.45 V reference; unused in fixed 3.3 V version (TPS62007DGSR) |
| ILIM (Pin 6) | Current-limit select | Ground = 600 mA limit; VIN = 1.2 A limit - sets peak switch current to prevent inductor saturation |
| SYNC (Pin 7) | Mode control | GND = PFM/PWM auto-switching; VIN = forced PWM; external CMOS clock = sync up to 1 MHz |
| EN (Pin 8) | Enable input | Active-high logic; <1 µA shutdown current when pulled 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 |
| PGND (Pin 10) | Power ground | Return path for high-current switches and inductor; must be connected to thermal pad for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P- and N-channel MOSFETs eliminate external diode, reducing conduction loss and enabling >95% efficiency |
| PFM/PWM hybrid control | Automatic transition at ~120 mA load preserves >85% efficiency from 1 mA to full 600 mA output |
| Antiringing switch (fixed-output only) | Suppresses parasitic LC oscillation during DCM, lowering radiated EMI without external snubbers |
| 100% duty-cycle operation | Maintains regulation down to VIN − VDROP (≈VIN − 0.2 V at 600 mA), critical for Li-ion end-of-discharge |
| Internal soft-start | ~1 ms voltage ramp prevents inrush current and output overshoot during enable transitions |

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 3.3 V output, identical pinout and specs except current limit set to 600 mA only (no ILIM-selectable 1.2 A mode) | Used where maximum 600 mA is sufficient and design simplicity is prioritized over current flexibility | Select TPS62006DGSR if ILIM pin routing is omitted and 1.2 A capability is unnecessary |
| TPS62231DRVR | Higher 3-MHz switching frequency, smaller 2.0 mm × 2.0 mm WSON package, 400 mA max output, different pinout | Targets ultra-compact, high-density designs where board area is more critical than peak current or legacy compatibility | Choose TPS62231DRVR only when redesigning for miniaturization and accepting reduced output current |

FAQ
What is the output voltage configuration of the TPS62007DGSR?
The TPS62007DGSR is a fixed-output variant delivering 3.3 V ±3% across its operating load range. Unlike the adjustable TPS62000, it uses an internal feedback divider and does not require external resistors on the FB pin. This simplifies design and improves accuracy for dedicated 3.3 V rail applications such as USB interfaces and microcontroller cores.
How does the ILIM pin affect current limiting in the TPS62007DGSR?
The ILIM pin on the TPS62007DGSR selects between two factory-trimmed current limits: tying ILIM to GND configures the device for 600 mA typical switch current limit, while connecting ILIM to VIN raises it to 1.2 A typical. This allows one PCB layout to support both moderate- and high-current versions without changing the IC footprint or external components.
Can the TPS62007DGSR operate with input voltages below 2.5 V?
Yes - the TPS62007DGSR operates down to 2 V input, making it suitable for deeply discharged single-cell Li-ion (≥2.0 V) and two-cell alkaline/NiMH batteries. Its 100% duty-cycle capability maintains regulation until VIN approaches VOUT + RDS(on) × IOUT, enabling extended runtime in portable devices before shutdown.
What is the purpose of the FC pin on the TPS62007DGSR?
The FC (Filter Capacitor) pin on the TPS62007DGSR serves as a dedicated high-frequency input bypass node. A 0.1 µF ceramic capacitor must be placed directly between FC and GND to filter switching noise and stabilize the internal bias circuitry. This is distinct from the main input capacitor (CIN) and is essential for low-noise operation and EMI compliance.
Does the TPS62007DGSR support synchronization to an external clock?
Yes - the SYNC pin accepts a CMOS-level external clock signal from 500 kHz to 1 MHz. When active, it forces the TPS62007DGSR into fixed-frequency PWM mode, disabling power-save PFM operation. This enables deterministic switching timing for noise-sensitive systems like audio codecs or RF sections, and allows synchronization with system clocks to avoid beat frequencies.
