Product details
Overview
TPS63011YFFT 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 mode transition, 96% peak efficiency, and integrated 2.2-A synchronous switches.
For engineers reviewing the TPS63011YFFT datasheet, TPS63011YFFT pinout, TPS63011YFFT application, or TPS63011YFFT equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in portable medical and audio devices, and validated alternative options for fixed 2.8 V / 3.3 V dual-output buck-boost regulation.
Technical Context
The TPS63011YFFT implements an average-current-mode, fixed-frequency PWM controller with four internal N-channel MOSFETs operating in complementary buck or boost configurations-never all switching simultaneously-to minimize RMS current, conduction loss, and switching loss. It uses separate GND (control logic) and PGND (power switch) pins to prevent ground shift under high-current transients.
Operation is governed by dual feedback loops: a fast inner current loop regulating average inductor current and an outer voltage loop comparing FB-sensed output against a 500 mV internal reference. Input and output voltage feedforward enables rapid transient response, while VSEL selects between two factory-trimmed output voltages (2.8 V or 3.3 V) without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Factory-fixed 3.3 V (VSEL = HIGH) or 2.8 V (VSEL = LOW); no external resistor divider required. |
| Max Output Current | 1200 mA at 3.3 V in step-down (VIN ≥ 3.6 V); 800 mA at 3.3 V in boost (VIN > 2.4 V). |
| Input Voltage Range | 2.0 V to 5.5 V continuous operation; 2.1 V minimum for startup. |
| Switching Frequency | 2.4 MHz typical (2.2–2.6 MHz); synchronizable up to 3 MHz via SYNC pin. |
| Peak Efficiency | 96% at mid-load (e.g., VIN = 3.6 V, VOUT = 3.3 V, IO = 500 mA). |
| Quiescent Current | ≤ 50 μA in power-save mode; ≤ 2 μA shutdown current (VEN = 0 V). |
| Protection Features | Output overvoltage clamp (6.5 V), thermal shutdown (140 °C), undervoltage lockout (1.7 V on VINA). |
Pinout & Package
TPS63011YFFT is housed in a 20-pin DSBGA (Die Size Ball Grid Array) package measuring 2.126 mm × 1.922 mm, with 0.4-mm pitch and bottom-side solder balls. The package supports compact layout and thermal performance via direct PCB copper contact through exposed PGND balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable control input | Active-high logic enable; pulls device into low-IQ shutdown when low. |
| FB | Feedback sense node | Internally connected to output for fixed-VOUT versions; must tie directly to VOUT (no divider). |
| GND | Control ground reference | Reference for logic, bias, and error amplifier; separate from PGND to avoid noise coupling. |
| L1 / L2 | Inductor connection points | Two dedicated terminals for single external inductor (1.5 µH typical); enables 4-switch buck-boost topology. |
| PGND | Power ground return | Low-impedance return path for high-current switch paths; connect to GND at single point near IC. |
| PS | Power-save mode control | Low = enable light-load efficiency optimization; high = forced fixed-frequency operation. |
| SYNC | External clock input | Accepts 2.2–3 MHz external clock; tie to GND if unused to avoid floating input. |
| VIN / VINA | Power stage & control supply | VIN powers switches; VINA powers control circuitry-both rated 2–5.5 V, with independent UVLO. |
| VOUT | Regulated output | Stable 2.8 V or 3.3 V output; capable of sourcing full load current with <0.5% line/load regulation. |
| VSEL | Output voltage select | Digital input selecting factory-trimmed output: HIGH → 3.3 V, LOW → 2.8 V (per datasheet Table 1). |
Key Features
| Feature | Design Value |
|---|---|
| Seamless buck-boost transition | Zero-output-voltage glitch during mode change; maintains regulation as VIN crosses VOUT (e.g., 3.0 V → 3.6 V). |
| Integrated 2.2-A synchronous switches | Eliminates external MOSFETs; 100 mΩ high- and low-side RDS(on) minimizes conduction loss at full load. |
| Load disconnect during shutdown | Internal switch isolates VOUT from VIN when EN = low-prevents battery drain and backfeed in portable systems. |
| Programmable power-save mode | Reduces switching frequency at light loads to maintain >85% efficiency down to 1 mA output current. |
| Robust protection suite | Includes OVP (6.5 V clamp), OTP (140 °C shutdown with 20 °C hysteresis), and UVLO (1.7 V on VINA). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63021DSJR | Higher 2.5-A switches, 3.5-MHz switching, smaller 12-pin WSON package; fixed 3.3 V only (no VSEL). | Targeted at space-constrained designs needing higher current and faster transient response. | Select when >1200 mA sustained load or <1 mm² footprint is required; not drop-in due to different pinout and no VSEL flexibility. |
| MAX77827BEWL+T | 3.2-A switches, I2C programmable output (2.5–5.2 V), integrated load switch; 1.84 mm × 1.44 mm WLP. | Suitable for systems requiring dynamic voltage scaling or controlled power sequencing. | Choose when firmware-controlled VOUT adjustment or integrated enable/disable of downstream rails is needed; requires I2C host. |
Compared with TPS63011YFFT, TPS63021DSJR offers higher current and frequency in a smaller package but lacks dual fixed outputs, while MAX77827BEWL+T adds programmability and integration at the cost of MCU dependency and higher BOM complexity.

FAQ
What is the exact output voltage configuration of TPS63011YFFT?
The TPS63011YFFT is a factory-trimmed fixed-output variant: it delivers either 2.8 V (when VSEL = LOW) or 3.3 V (when VSEL = HIGH), with tight tolerance (±1.5%) across temperature and load. Unlike the adjustable TPS63010, the TPS63011YFFT requires no external feedback resistors-FB must be directly connected to VOUT to close the regulation loop.
Does TPS63011YFFT support synchronization to an external clock?
Yes, TPS63011YFFT supports external clock synchronization via the SYNC pin, accepting input frequencies from 2.2 MHz to 3.0 MHz. When not used, SYNC must be tied to GND to prevent noise coupling; leaving it floating may cause erratic switching behavior or increased EMI.
How does TPS63011YFFT handle input voltage crossing the output voltage threshold?
The TPS63011YFFT automatically and seamlessly transitions between buck and boost modes as VIN rises above or falls below VOUT-without output glitches or control-loop interruption. This is achieved via its 4-switch topology with one switch held continuously on and another off, ensuring continuous regulation during the critical 2.8–3.3 V crossover region.
What thermal performance can be expected from TPS63011YFFT in a standard 2-layer PCB layout?
In a typical 2-layer board with 1 oz copper and moderate thermal relief, the TPS63011YFFT exhibits a junction-to-ambient thermal resistance (RθJA) of 71.1 °C/W. At 1200 mA output with 3.6 V input, power dissipation is ~350 mW, resulting in ~25 °C junction rise above ambient-well within the 125 °C max operating junction temperature.
Is load disconnect implemented in TPS63011YFFT during shutdown?
Yes, TPS63011YFFT fully disconnects the load from the input source during shutdown (EN = LOW). An internal switch opens between VIN and VOUT, preventing battery drain and eliminating backfeed risk-critical for battery-backed systems like medical monitors and handheld scanners where standby current must be minimized.
