Product details
Overview
TPS62207DBVTG4 from Texas Instruments is a fixed-output, synchronous step-down DC-DC converter in SOT-23-5 package, delivering 1.2 V at up to 300 mA with 2.5–6 V input range, 1 MHz fixed-frequency PWM operation, and 15 µA typical quiescent current in power save mode. It powers low-voltage logic in portable battery-powered devices such as smart phones and PDAs.
For engineers reviewing the TPS62207DBVTG4 datasheet, TPS62207DBVTG4 pinout, TPS62207DBVTG4 application, or TPS62207DBVTG4 equivalent, key selection criteria include its fixed 1.2 V output, SOT-23-5 footprint compatibility, efficiency above 90% at 10–100 mA loads (VI = 3.7 V), dynamic voltage positioning for transient headroom, and integrated P/N-channel MOSFETs eliminating external rectifier needs.
Technical Context
The TPS62207DBVTG4 employs a voltage-mode PWM controller with input voltage feed-forward for fast line/load regulation and supports seamless transition between 1 MHz PWM mode (moderate-to-heavy load) and pulse-frequency modulation (PFM) power save mode (light load). Its internal 0.5 V reference and fixed feedback divider set VO = 1.2 V without external resistors.
Functional blocks include undervoltage lockout (1.5–2.0 V threshold), soft-start (digital stepped current limiting, ~800 µs startup with 10 µF CO and 200 mA load), 100% duty-cycle low-dropout operation, and dynamic output voltage positioning-raising VO by ~0.8% at light load to minimize undershoot during sudden load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±3% over 0–300 mA load and 2.5–6 V input; enables direct powering of 1.2 V core rails without feedback resistor network. |
| Input Voltage Range | 2.5 V to 6.0 V; supports single-cell Li-ion (2.7–4.2 V), 3-cell NiMH/NiCd (3.6–4.5 V), and standard 3.3 V/5 V rails. |
| Max Output Current | 300 mA continuous; sufficient for low-power DSPs, microcontrollers, and RF ICs in handheld devices. |
| Switching Frequency | 650–1500 kHz typical (1 MHz nominal); enables use of small 10 µH inductors and 10 µF ceramic output capacitors. |
| Quiescent Current | 15 µA typical in power save mode; extends battery life in standby/sleep states of portable electronics. |
| Efficiency Peak | Up to 95% at VO = 1.8 V (per family data); TPS62207DBVTG4 achieves >92% at 1.2 V/100 mA with VI = 3.7 V per typical curves. |
| Thermal Resistance | RθJA = 220 °C/W (SOT-23-5); requires minimal PCB copper area for thermal management in space-constrained layouts. |
Pinout & Package
SOT-23-5 (DBV) package, 2.90 mm × 1.60 mm body size, 0.95 mm height, gull-wing leads; thermally enhanced for high-current DC-DC conversion in ultra-compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VI (Pin 1) | Power input | Accepts 2.5–6 V supply; connects to input capacitor (≥4.7 µF ceramic) placed adjacent to pin for low-impedance path. |
| GND (Pin 2) | Ground reference | Primary return path for power and control circuits; must be connected to low-impedance PCB ground plane. |
| EN (Pin 3) | Enable control | Active-high logic input; pull to VI to enable, to GND to shut down (0.1 µA IQ); must not float-requires explicit termination. |
| SW (Pin 5) | Switch node | Connects to inductor (10 µH typical); carries high di/dt switching current; layout critical to minimize EMI and voltage spikes. |
| FB (Pin 4) | Feedback input | Internally tied to fixed 1.2 V divider; no external resistors needed-simplifies BOM and layout versus adjustable versions. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains VO ~0.8% above nominal (1.21 V) at light load to reduce undershoot during 0→300 mA transients-enables stable 10 µF CO design. |
| Power Save Mode | Reduces switching frequency and IQ to 15 µA below ~10 mA load, preserving >85% efficiency down to 1 mA-critical for battery runtime. |
| Soft Start | Digital current-stepping (60→120→240→480 mA) limits inrush; achieves full regulation in ~800 µs with 10 µF CO and 200 mA load. |
| 100% Duty Cycle Operation | P-channel switch remains on when VI approaches VO; sustains regulation down to VI ≈ VO + IOUT × rDS(ON)_P, extending battery discharge time. |
| Synchronous Rectification | Integrated N-channel MOSFET replaces external Schottky diode-eliminates 0.3–0.5 V forward drop, improving light-load efficiency and thermal performance. |

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 |
|---|---|---|---|
| TPS62200DBVR | Adjustable output (0.7–VI) via external resistor divider; same 300 mA, 2.5–6 V, SOT-23-5 package; lacks fixed 1.2 V internal divider. | Requires two external resistors and optional noise-filtering capacitors on FB pin-increases BOM count and layout complexity. | Select when system requires programmable or non-standard output voltages (e.g., 1.35 V, 1.5 V) not offered in TPS6220x fixed variants. |
| TPS62231DRVR | Pin-compatible successor with 1.2 V fixed output, 300 mA, but improved specs: 17 µA IQ (vs 15 µA), 95% peak efficiency, and 2.05–6.0 V input range. | Supports lower VIN start-up (2.05 V) and includes integrated soft-start capacitor-reduces external component count vs TPS62207DBVTG4. | Choose for new designs needing extended battery life (lower cutoff) or tighter VO accuracy (±1.5% vs ±3%) without layout change. |
Compared with TPS62207DBVTG4, TPS62200DBVR offers flexibility at the cost of added components and noise sensitivity, while TPS62231DRVR provides higher integration and broader input range-but requires validation of revised thermal performance in legacy footprints.

FAQ
What is the fixed output voltage of the TPS62207DBVTG4?
The TPS62207DBVTG4 delivers a fixed 1.2 V output voltage with ±3% tolerance across temperature and load conditions. This value is set internally by a precision resistor divider referenced to the 0.5 V bandgap, eliminating the need for external feedback components-reducing BOM cost and PCB area versus adjustable variants like the TPS62200DBVR.
Does the TPS62207DBVTG4 require external feedback resistors?
No, the TPS62207DBVTG4 does not require external feedback resistors. Its FB pin is internally connected to a fixed voltage divider that sets the output to 1.2 V. Unlike the adjustable TPS62200DBVR, this eliminates resistor selection, layout sensitivity, and noise pickup concerns on the FB node-simplifying design and improving long-term stability.
What is the minimum input voltage required for regulation with the TPS62207DBVTG4?
The TPS62207DBVTG4 maintains regulation down to approximately 1.5 V input due to its undervoltage lockout threshold (1.5–2.0 V), but functional regulation at 1.2 V output begins when VI exceeds VO plus losses: VI(min) ≈ 1.2 V + IOUT × rDS(ON)_P. At 300 mA and max rDS(ON)_P = 850 mΩ (2.5 V VIN), VI(min) ≈ 1.46 V-enabling deep battery discharge utilization in Li-ion systems.
How does dynamic voltage positioning improve transient response in the TPS62207DBVTG4?
Dynamic voltage positioning raises the TPS62207DBVTG4 output to ~1.21 V (0.8% above nominal) during light-load power save mode. This intentional overvoltage provides headroom so that when a sudden 0→300 mA load step occurs, VO drops only to ~1.19 V-staying within ±2% regulation window without requiring oversized output capacitance or complex compensation.
Can the TPS62207DBVTG4 operate with a 10 µF output capacitor?
Yes, the TPS62207DBVTG4 is fully characterized and specified for stable operation with a 10 µF ceramic output capacitor (e.g., 0805 X5R/X7R). Its advanced voltage-mode control with input feed-forward ensures <1% undershoot/overshoot during 300 mA load transients-validated in TI's SLVS417F datasheet Figure 13-and eliminates need for larger or more expensive tantalum solutions.
