Product details
Overview
TPS62207DBVR from Texas Instruments is a fixed-output, synchronous step-down DC-DC converter delivering 1.2 V at up to 300 mA from a 2.5–6 V input. It employs 1-MHz PWM operation at medium-to-heavy loads and transitions to PFM power save mode at light loads, achieving up to 95% efficiency and 15 µA quiescent current. It powers low-voltage logic in portable battery-powered devices such as smart phones and PDAs.
For engineers reviewing the TPS62207DBVR datasheet, TPS62207DBVR pinout, TPS62207DBVR application, or TPS62207DBVR equivalent, key selection criteria include its fixed 1.2 V output, SOT-23-5 package footprint, 15 µA no-load IQ, dynamic voltage positioning for transient headroom, and compatibility with 4.7 µF input / 10 µF ceramic output capacitors.
Technical Context
The TPS62207DBVR implements a voltage-mode control architecture with input voltage feed-forward, enabling fast line and load regulation using small ceramic capacitors. Its internal 0.5 V reference feeds a GM amplifier that sets duty cycle via a sawtooth generator whose rise time scales with input voltage.
It integrates P-channel (670–850 mΩ @ 2.5 V) and N-channel (530–660 mΩ @ 2.5 V) MOSFET switches, supports 100% duty-cycle low-dropout operation, and uses undervoltage lockout (1.5–2.0 V threshold) and soft-start (800 µs typical with 10 µF/200 mA) to ensure robust startup and brownout protection.
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 - eliminates external feedback resistors and simplifies layout. |
| 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 - sufficient for powering low-power DSPs, microcontrollers, and RF ICs in handheld devices. |
| Switching Frequency | 650–1500 kHz (typ. 1 MHz) - enables compact 10 µH inductor and 10 µF ceramic output capacitor design. |
| No-Load Quiescent Current | 15 µA typical - extends battery life in standby/sleep modes of portable electronics. |
| Efficiency Peak | Up to 95% at VO = 1.2 V, VI = 3.7 V, IO = 100 mA - minimizes thermal stress and improves runtime. |
| Shutdown Current | 0.1 µA typical - ensures near-zero drain when disabled via EN pin. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VI (Pin 1) | Input supply connection | Accepts 2.5–6 V; requires local 4.7 µF ceramic decoupling placed adjacent to pin. |
| GND (Pin 2) | Power ground reference | Primary return path for input/output currents; must connect to low-impedance PCB ground plane. |
| EN (Pin 3) | Enable control input | Active-high logic: ≥1.3 V enables regulation; ≤0.4 V forces shutdown (0.1 µA IQ); must not float. |
| FB (Pin 4) | Feedback input | Internally connected to 1.2 V divider - no external components required; unused in fixed-output variants. |
| SW (Pin 5) | Switch node | Drives external 10 µH inductor; high dv/dt node requiring tight layout and minimal trace area to reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Output-Voltage Positioning | Output rises ~0.8% above 1.2 V at light load to provide headroom for load transients - reduces required output capacitance. |
| Power Save Mode (PFM) | Reduces switching frequency and IQ to 15 µA below ~60 mA load - maintains >85% efficiency down to 1 mA. |
| Soft Start | Digitally stepped current limit (60/120/240/480 mA) limits inrush - achieves 800 µs start-up with 10 µF/200 mA. |
| 100% Duty-Cycle Operation | P-channel switch remains fully on when VI approaches VO - extends usable battery range down to ~1.3 V input. |
| Undervoltage Lockout (UVLO) | Disables operation below 1.5–2.0 V - prevents erratic switching and protects system during deep battery discharge. |
Applications
| Smartphone Baseband Power | PDA Application Processor Core |
|---|---|
Use Scenario: Powers ARM-based application processor core (e.g., OMAP, i.MX) requiring stable 1.2 V at up to 250 mA during active mode and sub-mA leakage in suspend. IC Role / Device Role / Timing Role: Primary point-of-load (POL) regulator converting battery or PMIC rail to processor core voltage. Use Value: Dynamic voltage positioning provides 9.6 mV headroom to absorb load-step-induced droop without undershoot, enabling use of only 10 µF output capacitance. |
Use Scenario: Supplies 1.2 V to PDA main CPU (e.g., PXA270) during video decode or UI rendering, then drops to light-load PFM mode during idle screen display. IC Role / Device Role / Timing Role: High-efficiency buck converter operating in PWM mode at >60 mA and PFM below - minimizing average IQ. Use Value: 15 µA quiescent current extends battery runtime by >12 hours in standby versus comparable 50 µA alternatives. |
| Digital Camera Image Sensor Bias | Portable Media Player Audio Codec |
Use Scenario: Provides clean, low-noise 1.2 V bias to CMOS image sensor analog front-end during capture bursts, handling rapid 0→300 mA load steps. IC Role / Device Role / Timing Role: Fast-transient POL regulator with voltage-mode control and feed-forward - reducing output deviation to <24 mV. Use Value: 1-MHz fixed-frequency PWM ensures predictable noise spectrum, easing EMI filtering in camera module PCB layout. |
Use Scenario: Powers stereo audio DAC/ADC subsystem (e.g., WM8731) requiring regulated 1.2 V with <1% ripple during playback. IC Role / Device Role / Timing Role: Low-ripple DC-DC source replacing LDO to improve efficiency in battery-constrained media players. Use Value: 95% peak efficiency at 100 mA reduces heat generation by 4× versus 75% efficient alternative - critical in sealed plastic enclosures. |
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 |
|---|---|---|---|
| TPS62202DBVR | Fixed 1.8 V output; identical package, pinout, and control architecture. | Requires redesign of downstream logic voltage levels; unsuitable where 1.2 V core rail is mandated. | Select only if system already uses 1.8 V core and board layout accommodates same SOT-23-5 footprint. |
| TPS62231DRVR | Higher 2-MHz switching frequency; 1.2 V output; 400 mA rating; 1.8–6.5 V input; WSON-6 package. | Enables smaller 4.7 µH inductor and 4.7 µF output cap; requires PCB rework due to different package and pin count. | Prefer for new designs needing higher current or smaller solution size; not drop-in compatible with TPS62207DBVR. |
Compared with TPS62202DBVR, the TPS62207DBVR enables lower-voltage SoC cores without external resistor networks; compared with TPS62231DRVR, it offers proven legacy reliability in space-constrained SOT-23-5 but trades off higher current capability and frequency scalability.

FAQ
What is the output voltage tolerance of the TPS62207DBVR across temperature and load?
The TPS62207DBVR maintains a fixed 1.2 V output with ±3% tolerance over the full operating ambient temperature range (–40°C to +85°C) and full load range (0–300 mA). This specification is guaranteed under recommended conditions: VI = 2.5–6 V, and includes line regulation (0.26%/V) and load regulation (0.0014%/mA) contributions per the SLVS417F datasheet.
Does the TPS62207DBVR require external feedback resistors?
No, the TPS62207DBVR does not require external feedback resistors. As a fixed-output variant, it integrates an internal resistor divider referenced to a 0.5 V internal bandgap, setting the output precisely to 1.2 V. The FB pin is internally connected and must not be externally loaded or modified - doing so will disrupt regulation.
How does the TPS62207DBVR achieve high efficiency at light loads?
The TPS62207DBVR achieves high light-load efficiency by automatically entering power save mode (PFM), where switching frequency decreases and quiescent current drops to 15 µA typical. This mode activates when load falls below ~60 mA, reducing switching losses while maintaining regulation via comparator-controlled pulse bursts - sustaining >85% efficiency down to 1 mA.
Can the TPS62207DBVR operate with a 2.5 V input and 1.2 V output?
Yes, the TPS62207DBVR supports 2.5 V input at 1.2 V output via 100% duty-cycle operation: the internal P-channel MOSFET remains continuously on, eliminating switching losses. Under these conditions, minimum input is limited by P-channel Rds(on) and inductor DCR - typical dropout is <150 mV at 300 mA, allowing functional regulation down to ~1.35 V input.
What is the recommended input and output capacitor configuration for the TPS62207DBVR?
Texas Instruments recommends a 4.7 µF X5R/X7R ceramic capacitor (0805 case) placed adjacent to the VI pin, and a 10 µF X5R/X7R ceramic capacitor (0805 case) at the output. These values ensure stable operation, meet ripple and transient requirements, and align with the device's voltage-mode control loop bandwidth - no additional bulk or tantalum capacitors are needed.
