Product details
Overview
TPS62200DBVR from Texas Instruments is a synchronous step-down DC-DC converter in a 5-pin SOT-23 package, delivering up to 300 mA output current with adjustable output voltage (0.7 V to VI), 2.5–6 V input range, and 1 MHz fixed-frequency PWM operation. It powers low-voltage DSPs and processors in battery-powered portable electronics.
For engineers reviewing the TPS62200DBVR datasheet, TPS62200DBVR pinout, TPS62200DBVR application, or TPS62200DBVR equivalent, key selection criteria include its 15 µA typical quiescent current in power save mode, dynamic voltage positioning for transient headroom, soft-start functionality, 100% duty cycle low-dropout operation, and compatibility with small ceramic input/output capacitors (4.7 µF / 10 µF).
Technical Context
The TPS62200DBVR implements a fast-response voltage-mode control architecture with input voltage feed-forward, enabling stable regulation using only small ceramic capacitors. Its dual-mode operation-fixed-frequency PWM at medium-to-heavy loads and pulse-frequency modulation (PFM) at light loads-maintains >90% efficiency across 10 µA–300 mA load range.
Internally, it integrates P-channel and N-channel MOSFET switches (rDS(on) ≤850 mΩ and ≤660 mΩ respectively at 2.5 V), a 0.5 V reference amplifier, undervoltage lockout (1.5–2.0 V threshold), and comparator-based dynamic voltage positioning that raises output by ~0.8% at light load to minimize drop during sudden load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 6.0 V - supports single-cell Li-ion (2.7–4.2 V) and standard 3.3 V/5 V rails without external regulators. |
| Output Voltage Range | 0.7 V to VI - adjustable via external resistor divider; enables precise biasing of modern low-voltage cores (e.g., 1.2 V, 1.5 V, 1.8 V). |
| Max Output Current | 300 mA - sufficient for powering ARM Cortex-M microcontrollers, audio codecs, or RF front-end ICs in compact designs. |
| Switching Frequency | 650–1500 kHz (typ. 1 MHz) - allows use of small 10 µH inductors and minimizes EMI filtering requirements. |
| Quiescent Current | 15 µA (typ.) in power save mode - extends battery life in always-on sensor nodes or standby subsystems. |
| Feedback Reference | 0.5 V - low-reference design reduces divider current and improves noise immunity when paired with high-impedance resistors. |
| Thermal Resistance | RθJA = 220 °C/W - requires minimal PCB copper area for thermal management in space-constrained SOT-23 layouts. |
Pinout & Package
TPS62200DBVR uses a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for high-density portable PCBs. The pinout is validated per TI SLVS417F Rev F (June 2015).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VI (Pin 1) | Power input | Accepts 2.5–6 V supply; must be decoupled with ≥4.7 µF ceramic capacitor placed adjacent to pin. |
| GND (Pin 2) | Ground reference | Primary return path for power and feedback circuits; connects directly to thermal pad on PCB for heat dissipation. |
| EN (Pin 3) | Enable control | Active-high logic input; pulling low disables converter and reduces quiescent current to 0.1 µA - critical for system-level power sequencing. |
| FB (Pin 4) | Feedback node | Connects to resistor divider output; internal 0.5 V reference enables precise output setting; sensitive to noise - requires guard ring or RC filtering. |
| SW (Pin 5) | Switch node | Drives external inductor; carries high di/dt switching current - layout must minimize loop area to reduce EMI and voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Raises output ~0.8% above nominal at light load to provide headroom for rapid load transients - eliminates need for oversized output capacitance. |
| 100% Duty Cycle Operation | Enables regulation down to VIN – VOUT ≈ 100 mV at full load - maximizes usable battery voltage range in Li-ion applications. |
| Soft Start | Digitally controlled current ramp (60/120/240/480 mA steps) limits inrush current - prevents input rail collapse during cold start from weak sources. |
| Power Save Mode | Reduces switching frequency and quiescent current to 15 µA below ~10 mA load - maintains >85% efficiency even at 100 µA output current. |
| Undervoltage Lockout | Disables operation below 1.5–2.0 V input - prevents erratic behavior during battery brownout or startup sequencing. |
Applications
| Smartphone Baseband Power | PDA Application Processor Supply |

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 |
|---|---|---|---|
| TPS62231DBVR | Higher 2-MHz switching frequency; 400-mA output; integrated soft-start; tighter output accuracy (±1.5% vs ±3%). | Requires smaller 4.7-µH inductor; better suited for ultra-thin devices needing faster transient response. | Select when board space is constrained and higher accuracy is required; not drop-in due to different FB divider ratio and enable timing. |
| AP3418W6-7 | Fixed 1.8-V output; 300-mA rating; 1.5-MHz switching; 25-µA quiescent current; no dynamic voltage positioning. | Lacks adjustable output and DVP - suitable only for static-rail applications like memory I/O or LED drivers. | Choose for cost-sensitive, fixed-voltage designs where 10 µA quiescent current advantage is not critical. |
Compared with TPS62200DBVR, TPS62231DBVR offers higher integration and precision at the cost of increased complexity and non-interchangeable feedback network, while AP3418W6-7 trades configurability and ultra-low IQ for lower BOM count in fixed-rail systems.

FAQ
What is the minimum input voltage required for TPS62200DBVR to maintain regulation at 300 mA output?
The TPS62200DBVR supports 100% duty cycle operation, allowing regulation down to VOUT + IOUT × rDS(ON)(max) + IOUT × RL. At 300 mA and 1.8 V output, with max P-channel rDS(ON) of 850 mΩ and typical 50 mΩ inductor DCR, minimum input is ~2.1 V. This enables full utilization of discharged Li-ion cells.
How does the TPS62200DBVR achieve high efficiency at light loads?
The TPS62200DBVR enters power save mode below ~10 mA load, switching from fixed-frequency PWM to pulse-frequency modulation (PFM). In this mode, switching frequency drops and quiescent current falls to 15 µA (typ.), sustaining >85% efficiency even at 100 µA output - critical for always-on sensor subsystems.
Can the TPS62200DBVR be used with a 3.3 V input to generate 1.2 V output?
Yes. With VI = 3.3 V and VO = 1.2 V, the TPS62200DBVR operates within its 2.5–6 V input and 0.7–VI output ranges. Using R1 = 1.1 MΩ and R2 = 560 kΩ yields 1.2 V (VREF × (1 + R1/R2) = 0.5 V × 2.96). The 1 MHz switching frequency ensures stable regulation with standard 10 µH inductors.
What is the purpose of dynamic voltage positioning in the TPS62200DBVR?
Dynamic voltage positioning raises the TPS62200DBVR output ~0.8% above nominal at light load. This provides headroom to absorb voltage droop during sudden load increases (e.g., CPU wake-up), reducing required output capacitance and minimizing transient undershoot without compromising steady-state accuracy.
Is an external soft-start capacitor required for the TPS62200DBVR?
No. The TPS62200DBVR features internal digital soft-start that ramps switch current in discrete steps (60/120/240/480 mA), achieving typical 800 µs startup time with 10 µF output capacitance and 200 mA load. No external components are needed - simplifying layout and reducing BOM count.
