Product details
Overview
TPS63011YFFR from Texas Instruments is a highly efficient, single-inductor buck-boost DC/DC converter optimized for battery-powered systems requiring stable 3.3 V output at up to 1200 mA in step-down mode (VIN = 3.6–5.5 V) and up to 800 mA in boost mode (VIN > 2.4 V), with automatic seamless transition between modes and fixed 3.3 V output when VSEL = HIGH.
For engineers reviewing the TPS63011YFFR datasheet, TPS63011YFFR pinout, TPS63011YFFR application, or TPS63011YFFR equivalent, key selection considerations include its 2.126 mm × 1.922 mm DSBGA package, 2.0–5.5 V input range, 96% peak efficiency, integrated 2-A synchronous switches, and dual fixed-output voltage selection (2.8 V / 3.3 V) via VSEL logic control.
Technical Context
The TPS63011YFFR implements an average-current-mode, fixed-frequency PWM controller with four internal N-channel MOSFETs operating in a 4-switch buck-boost topology-never all switching simultaneously-to minimize RMS current, conduction loss, and switching loss. It uses separate GND (control) and PGND (power) pins to prevent ground shift under high transient currents.
Operation dynamically shifts between buck and boost based on VIN vs. VOUT relationship: buck mode when VIN > VOUT, boost when VIN < VOUT, with seamless transition and no dead zone. Feedback is internally trimmed for fixed 3.3 V output (VSEL = HIGH) or 2.8 V (VSEL = LOW); FB pin connects directly to VOUT, not used for external divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V (VSEL = HIGH) or 2.8 V (VSEL = LOW); no external resistor required - simplifies BOM and layout. |
| Max Output Current | 1200 mA at 3.3 V in step-down (VIN ≥ 3.6 V); enables direct powering of 3.3 V microcontrollers and RF modules from Li-ion or multi-cell alkaline. |
| Input Voltage Range | 2.0 V to 5.5 V - supports discharge down to 2.5 V from single-cell Li-ion and operation across two/three-cell alkaline/NiMH. |
| Peak Efficiency | 96% - achieved at mid-load in step-down mode; reduces thermal stress and extends battery runtime in portable devices. |
| Switching Frequency | 2.4 MHz typical (2.2–2.6 MHz) - allows use of small 1.5 µH inductors and 10 µF ceramic output capacitors for compact PCB area. |
| Quiescent Current | ≤50 µA in power-save mode - critical for maintaining >100-hour standby in medical sensors and remote IoT endpoints. |
| Thermal Resistance | RθJA = 71.1 °C/W (DSBGA YFF) - enables 1200 mA operation without forced air in ≤25°C ambient with minimal copper pour. |
Pinout & Package
TPS63011YFFR is housed in a 20-pin, 2.126 mm × 1.922 mm DSBGA (Die Size Ball Grid Array) package with 0.4 mm pitch, designed for ultra-compact portable applications and requiring microvia-in-pad assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH ≥ 1.2 V); disables converter and disconnects load from input during shutdown - prevents battery drain. |
| FB | Feedback input | Internally connected to VOUT for fixed-output versions; must be shorted to VOUT - no external divider needed. |
| VIN / VINA | Power inputs | VIN supplies power stage; VINA supplies control circuitry - decoupling each separately improves noise immunity and startup reliability. |
| L1 / L2 | Inductor connections | Dual inductor terminals for single-coil buck-boost topology; requires 1.5 µH low-DCR shielded inductor with ≥2.5 A saturation current. |
| VOUT | Regulated output | Delivers fixed 3.3 V (VSEL = HIGH) with ±1.5% tolerance over temperature and line/load - suitable for MCU I/O and analog peripherals. |
| PGND / GND | Ground terminals | PGND carries high-switching-current return path; GND is control-reference ground - must connect at single point near IC for EMI control. |
| VSEL | Output voltage select | Logic input selecting 3.3 V (HIGH) or 2.8 V (LOW); enables dual-voltage system support without changing BOM. |
| PS | Power-save mode control | Low = enable power-save (variable frequency at light load); High = forced fixed-frequency operation - tradeoff between efficiency and EMI. |
| SYNC | External clock input | Accepts 2.2–3.0 MHz external clock for EMI reduction or synchronization with other converters - tie to GND if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamless, zero-interruption switchover between step-down and boost when VIN crosses VOUT - maintains uninterrupted 3.3 V supply during battery discharge. |
| Load disconnect during shutdown | Internal switch isolates VOUT from VIN when EN = LOW - eliminates reverse leakage and preserves battery charge in storage or sleep states. |
| Integrated overvoltage protection | Clamps output at 6.5 V independent of feedback path failure - protects downstream 3.3 V logic from catastrophic damage due to open-FB or trace lift-off. |
| Overtemperature shutdown with hysteresis | Shuts down at 140°C junction temperature and restarts at 120°C - prevents thermal runaway while avoiding oscillatory cycling near thermal limit. |
| Synchronous 4-switch architecture | Uses four internal N-MOSFETs with optimized gate drive timing - eliminates external diodes, reduces conduction loss, and achieves >90% efficiency down to 10 mA load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63020DSJR | Higher 2.5-A switch current rating; 2.4-MHz fixed frequency only; no VSEL pin - fixed 3.3 V output only. | Supports higher peak loads (e.g., camera flash LEDs); lacks dual-voltage flexibility of TPS63011YFFR. | Select when >1.2 A continuous load or stricter EMI control is required, and dual output voltage is unnecessary. |
| MAX77827BEFG+T | 3.2-MHz switching; integrated input OVP (6.8 V); smaller 1.67 mm × 1.67 mm WLP package; 1.8–5.5 V input. | Better suited for space-constrained wearables; lacks power-save mode and has lower 800 mA max output at 3.3 V. | Select when board area is critical and peak current demand is ≤800 mA; verify thermal performance under sustained load. |
Compared with TPS63020DSJR and MAX77827BEFG+T, the TPS63011YFFR uniquely balances compact DSBGA size, dual fixed-output selection via VSEL, and proven 1200 mA capability at 3.3 V - making it optimal for cost-sensitive, battery-life-critical portable designs needing flexible voltage configuration without redesign.

FAQ
What is the exact output voltage of TPS63011YFFR and how is it selected?
The TPS63011YFFR provides two factory-trimmed fixed output voltages: 2.8 V when VSEL is pulled LOW, and 3.3 V when VSEL is pulled HIGH. The FB pin is internally connected to VOUT and must be shorted to the output node - no external resistor divider is used or supported. This eliminates tuning variability and ensures ±1.5% output accuracy across temperature and load.
Does TPS63011YFFR require external compensation components?
No, the TPS63011YFFR uses internal compensation optimized for its 2.4 MHz switching frequency and recommended 1.5 µH inductor + 10 µF ceramic output capacitor. No external RC network or compensation pins are provided - simplifying design, reducing BOM count, and eliminating stability tuning effort for standard configurations.
How does TPS63011YFFR handle input voltage transitions near the output voltage?
The TPS63011YFFR employs a seamless buck-to-boost transition mechanism that avoids output droop or discontinuity when VIN approaches VOUT. Its 4-switch topology dynamically reconfigures conduction paths - maintaining regulation without mode-hopping artifacts or audible inductor whine - critical for noise-sensitive audio and sensor applications.
Can TPS63011YFFR operate from a single 1.5 V alkaline cell?
No - the TPS63011YFFR requires minimum 2.0 V input to start and sustain regulation. A single fresh alkaline cell (1.6 V) or partially discharged cell (<2.0 V) cannot power the device. It is intended for two-cell alkaline (2.4–3.2 V), three-cell alkaline (3.6–4.8 V), or single-cell Li-ion (2.8–4.2 V) sources.
What thermal derating applies to TPS63011YFFR at 85°C ambient?
At TA = 85°C, the TPS63011YFFR's maximum continuous output current is reduced to approximately 750 mA at 3.3 V due to thermal limits (RθJA = 71.1 °C/W). Derating follows 12 mW/°C above 25°C ambient; full 1200 mA is only sustainable below ~45°C ambient with standard 2-layer PCB copper pour.
