Product details
Overview
TPS63012YFFR from Texas Instruments is a highly efficient, single-inductor buck-boost DC/DC converter optimized for fixed 3.4 V output in boost mode and 2.9 V in buck mode, supporting up to 1200 mA at 3.3 V (VIN = 3.6 V), 800 mA at 3.3 V in boost (VIN > 2.4 V), and operating across 2 V–5.5 V input range. It delivers seamless automatic transition between buck and boost modes for battery-powered portable electronics requiring stable rail regulation across varying cell voltage.
For engineers reviewing the TPS63012YFFR datasheet, TPS63012YFFR pinout, TPS63012YFFR application, or TPS63012YFFR equivalent, key selection considerations include its 20-pin DSBGA (2.126 mm × 1.922 mm) package, VSEL-controlled dual-output-voltage capability, synchronous 4-MOSFET topology, power-save mode for light-load efficiency, and integrated overvoltage/overtemperature protection.
Technical Context
The TPS63012YFFR implements an average-current-mode, fixed-frequency PWM controller with synchronous rectification using four internal N-channel MOSFETs-two active per phase, one permanently on, one permanently off-to minimize switching losses and maintain >96% peak efficiency. Its dual-ground architecture (GND for control, PGND for power) isolates high-current paths while enabling precise feedback via FB pin tied directly to VOUT for fixed-output variants.
Operation is governed by real-time input/output voltage monitoring: when VIN > VOUT, it functions as a buck converter; when VIN < VOUT, it transitions seamlessly to boost mode without discontinuity. The VSEL pin selects between two factory-trimmed output voltages (2.9 V or 3.4 V), and PS pin enables/disables power-save mode to sustain high efficiency down to microamp load currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 5.5 V - supports full discharge of single-cell Li-ion (down to 2.5 V) and multi-cell alkaline/NiMH batteries. |
| Output Voltage Options | 2.9 V (VSEL = LOW) or 3.4 V (VSEL = HIGH) - factory-trimmed, no external resistor divider required. |
| Max Output Current | 1200 mA at 3.3 V in step-down (VIN = 3.6 V–5.5 V); 800 mA at 3.3 V in boost (VIN > 2.4 V) - defined by 2.2 A typical switch current limit. |
| Switching Frequency | 2.4 MHz typical (2.2–2.6 MHz) - enables use of small 1.5 µH inductors and 10 µF ceramic output capacitors. |
| Quiescent Current | ≤50 µA - ensures minimal battery drain during standby in always-on portable devices. |
| Protection Features | Output overvoltage (6.5 V), overtemperature (140 °C with 20 °C hysteresis), and load disconnect during shutdown - enhances system reliability without external circuitry. |
| Efficiency | Up to 96% - achieved via synchronous 4-MOSFET topology and optimized gate drive minimizing conduction and switching losses. |
Pinout & Package
TPS63012YFFR is housed in a 20-pin DSBGA package measuring 2.126 mm × 1.922 mm (YFF), with 0.4 mm pitch and bottom-side solder balls. Thermal performance is characterized by RθJA = 71.1 °C/W and RθJB = 11.4 °C/W, supporting compact PCB layouts in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control: drives device into low-IQ shutdown (≤1 µA) with load disconnect from input. |
| VIN / VINA | Power stage / control stage supply | VIN powers switches; VINA powers control circuitry - separate pins enable independent filtering and noise isolation. |
| L1 / L2 | Inductor connections | Two dedicated inductor terminals support single-inductor buck-boost topology; require low-ESR 1.5 µH inductor. |
| VOUT | Regulated output | Delivers fixed 2.9 V or 3.4 V depending on VSEL state; connects directly to FB for internal feedback loop closure. |
| FB | Feedback input | Internally connected to output for fixed-voltage versions - no external divider needed; must tie to VOUT. |
| VSEL | Output voltage select | Digital input selecting between two factory-trimmed outputs: LOW → 2.9 V, HIGH → 3.4 V. |
| PS | Power-save mode control | LOW enables power-save mode for improved light-load efficiency; HIGH forces fixed-frequency operation. |
| SYNC | External clock synchronization | Accepts external 2.2–3 MHz clock signal; tie to GND if unused to avoid noise coupling. |
| GND / PGND | Control / power ground | Separate grounds prevent ground bounce; must connect at single point near GND pin to avoid noise injection. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamless, discontinuity-free regulation across VIN = 2 V to 5.5 V without manual reconfiguration or external control logic. |
| Synchronous 4-MOSFET topology | Eliminates external diodes and reduces conduction loss; achieves 96% peak efficiency with minimal thermal rise. |
| VSEL-programmable dual output | Two precision-trimmed output voltages (2.9 V / 3.4 V) selected by single logic-level pin - no BOM change required for voltage variant. |
| Integrated overvoltage protection | Clamps output at 6.5 V during feedback failure or open-FB condition - prevents damage to downstream 3.3 V logic rails. |
| Load disconnect during shutdown | Physically isolates VOUT from VIN when EN = LOW - eliminates battery drain and prevents backfeed in multi-rail systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63011YFFR | Fixed 3.3 V / 2.8 V outputs (vs. TPS63012YFFR's 3.4 V / 2.9 V); identical pinout, package, and feature set. | Preferred where 3.3 V logic compatibility is mandatory and 0.1 V higher output tolerance is acceptable. | Select TPS63011YFFR only if system requires exact 3.3 V nominal rail; otherwise TPS63012YFFR offers tighter regulation margin for 3.4 V sensor biasing. |
| TPS63020DSJR | Higher 2.5-A switch current limit, 3.5-MHz switching frequency, and adjustable output (0.8–5.5 V) - larger 10-pin SON package. | Suitable for higher-current or programmable-voltage applications where board area allows larger package and layout complexity increases. | Choose TPS63020DSJR only when >1.2 A continuous output or adjustable VOUT is required; TPS63012YFFR remains optimal for cost- and size-sensitive fixed-voltage designs. |
Compared with TPS63011YFFR, TPS63012YFFR provides 0.1 V higher output options ideal for noise-margin-critical analog sensors; versus TPS63020DSJR, it trades programmability and current headroom for 45% smaller footprint and lower BOM count in fixed-rail portable systems.

FAQ
What is the exact output voltage configuration of the TPS63012YFFR?
The TPS63012YFFR is a fixed-output buck-boost converter with two factory-trimmed voltage options selected by the VSEL pin: 2.9 V when VSEL = LOW and 3.4 V when VSEL = HIGH. Unlike adjustable versions, it requires no external resistor divider - FB is internally connected to VOUT for closed-loop regulation.
Does the TPS63012YFFR support synchronization to an external clock?
Yes, the TPS63012YFFR 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; floating the pin may cause erratic operation or increased EMI.
How does the TPS63012YFFR handle input voltage transitions across the output voltage threshold?
The TPS63012YFFR automatically and seamlessly transitions between buck and boost modes without output disruption or control-loop instability. Its average-current-mode controller continuously monitors VIN and VOUT, adjusting duty cycle and switch configuration in real time to maintain regulation across the entire 2 V–5.5 V input range.
What thermal performance can be expected from the TPS63012YFFR in a standard 2-layer PCB layout?
In a standard 2-layer PCB with 1 oz copper and moderate copper pour on both layers, the TPS63012YFFR exhibits RθJB = 11.4 °C/W. At 1200 mA output with 3.6 V input, junction temperature rise is typically ≤25 °C above ambient - well within the 125 °C max operating limit and enabling fanless operation.
Is load disconnect implemented during shutdown of the TPS63012YFFR?
Yes, the TPS63012YFFR physically disconnects the load from the input source during shutdown (EN = LOW), reducing system standby current to ≤1 µA. This prevents battery drain and eliminates backfeed risk in multi-rail systems - a critical feature for always-on portable devices.
