Product details
Overview
TPS62262DRVT from Texas Instruments is a 1.2-V fixed-output, 600-mA synchronous step-down DC/DC converter in a 2-mm × 2-mm WSON-6 package. It operates from 2 V to 6 V input, delivers ±1.5% output voltage accuracy in PWM mode, features 2.25-MHz fixed-frequency switching, and supports power save mode with dynamic voltage positioning for battery-powered systems.
For engineers reviewing the TPS62262DRVT datasheet, TPS62262DRVT pinout, TPS62262DRVT application, or TPS62262DRVT equivalent, key selection criteria include its 1.2-V fixed output, MODE pin-controlled PFM/PWM transition, 15-μA quiescent current in light-load PFM mode, thermal shutdown at 140°C, and compatibility with 2.2-μH inductors and 10-μF ceramic output capacitors.
Technical Context
The TPS62262DRVT uses voltage-mode control with input voltage feed-forward for fast line/load regulation and enables stable operation with small ceramic capacitors. Its internal 0.6-V reference and fixed 1.2-V output are achieved via integrated resistor divider - eliminating external FB resistors.
It implements automatic PFM-to-PWM mode transition based on load current, with dynamic voltage positioning (+1% nominal) active in PFM mode to minimize load-step undershoot. The MODE pin forces fixed-frequency PWM when pulled high, while grounding it enables optimized efficiency across 0–600 mA load range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1.5% in PWM mode; ensures stable core supply for low-voltage processors and FPGAs |
| Max Output Current | 600 mA at VIN ≥ 2.5 V; supports single-core microcontrollers and sensor subsystems |
| Input Voltage Range | 2 V to 6 V; compatible with single Li-ion (2.7–4.2 V), two/three-cell alkaline, and 3.3/5-V rails |
| Switching Frequency | 2.25 MHz (±12.5%); enables use of 2.2-μH inductors and <1-mm solution height |
| Quiescent Current | 15 μA in PFM mode (MODE = GND); extends battery life in standby/sleep states |
| Shutdown Current | 0.1–1 μA (EN = GND); prevents battery drain during system off-state |
| Thermal Shutdown | 140°C with 20°C hysteresis; protects against sustained overload or poor PCB thermal design |
Pinout & Package
TPS62262DRVT is housed in a thermally enhanced 6-pin WSON package (2.00 mm × 2.00 mm × 0.8 mm) with exposed thermal pad (Pin 6 = Power PAD).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power input | Accepts 2–6 V; requires local 4.7-μF ceramic decoupling close to pin |
| GND (Pin 6) | Ground reference | Connects to thermal pad and system ground plane for optimal heat dissipation |
| EN (Pin 4) | Enable control | Active-high logic; pull low to enter <1-μA shutdown; supports power sequencing |
| SW (Pin 1) | Switch node | Drives external 2.2-μH inductor; requires short, low-inductance routing to minimize EMI |
| FB (Pin 3) | Feedback input | Internally connected to fixed 1.2-V divider; leave floating - no external resistors needed |
| MODE (Pin 2) | Operation mode select | Pull to GND for auto PFM/PWM; pull to VIN for forced 2.25-MHz PWM in noise-sensitive apps |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to reduce load-step undershoot by up to 12 mV |
| 100% Duty Cycle Operation | Enables dropout as low as ~120 mV at 600 mA (RDS(on) + DCR dependent), extending battery runtime |
| Integrated Soft Start | Ramps VOUT from 5% to 95% in 250 μs to limit inrush current and prevent input rail collapse |
| Undervoltage Lockout (UVLO) | Disables regulator below 1.85 V (falling) to prevent brownout operation and deep battery discharge |
| Short-Circuit Protection | Current-limited switching (ILIMF = 0.8–1.2 A) with automatic recovery avoids latch-up during output faults |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261DRVR | 1.8-V fixed output; same package, pinout, and electrical specs except VOUT | Requires board-level redesign if 1.2-V rail is mandatory; suitable only where 1.8-V logic supply is acceptable | Select when system uses 1.8-V I/O domains and needs identical footprint/thermal performance |
| TPS62822DDCR | 1.2-V fixed, 2-A output, 4-MHz switching, 0.9-mm height; newer generation with lower IQ (0.35 μA) | Higher current and frequency enable smaller magnetics but require layout revalidation due to faster edges | Choose for next-gen designs needing higher headroom or longer battery life; not drop-in compatible |
Compared with TPS62262DRVT, TPS62261DRVR offers identical form-factor and efficiency but targets 1.8-V loads, while TPS62822DDCR provides double the current and modern ultra-low IQ at the cost of non-pin-compatible packaging and revised EMI mitigation requirements.

FAQ
What is the output voltage tolerance of the TPS62262DRVT under full load and temperature range?
The TPS62262DRVT guarantees ±1.5% output voltage accuracy in PWM mode across 2.5 V ≤ VIN ≤ 6 V, 0 mA ≤ IOUT ≤ 600 mA, and –40°C ≤ TA ≤ 85°C. This specification includes initial tolerance, line regulation, load regulation, and temperature drift - verified per TI's SLVS763E datasheet Section 7.5.
Does the TPS62262DRVT require external feedback resistors to set its 1.2-V output?
No. The TPS62262DRVT integrates the feedback resistor divider for its fixed 1.2-V output. Pin FB is internally connected and must be left unconnected - no external resistors are required or recommended. This simplifies layout and eliminates resistor tolerance errors affecting regulation accuracy.
How does the MODE pin affect efficiency and noise performance of the TPS62262DRVT?
When MODE = GND, the TPS62262DRVT enters power save mode with automatic PFM/PWM transition, achieving >85% efficiency at 1 mA and >90% at 100 mA. When MODE = VIN, it operates in fixed 2.25-MHz PWM mode - reducing output voltage ripple and EMI but lowering light-load efficiency to ~70% at 1 mA.
What is the minimum input voltage required for the TPS62262DRVT to maintain 1.2-V regulation at 600 mA?
Using the formula VINmin = VOUTmax + IOUTmax × (RDS(on)max + RL), with VOUTmax = 1.218 V (1.2 V + 1.5%), IOUTmax = 0.6 A, RDS(on)max = 480 mΩ (high-side), and RL = 110 mΩ (typical 2.2-μH inductor), VINmin ≈ 1.218 V + 0.6 A × 0.59 Ω = 1.572 V. However, UVLO (1.85 V) and recommended operating conditions (VIN ≥ 2 V) dictate practical minimum as 2 V.
Can the TPS62262DRVT safely operate without an output capacitor?
No. The TPS62262DRVT requires a minimum 4.7-μF ceramic output capacitor (X5R/X7R dielectric) for stability and transient response. Omitting COUT causes oscillation, excessive output ripple (>200 mV), and potential damage due to uncontrolled switch-node voltage spikes - as specified in Section 9.2.2.2 of the SLVS763E datasheet.
