Product details
Overview
TPS63010YFFR from Texas Instruments is a highly efficient, single-inductor buck-boost DC/DC converter in a 20-pin DSBGA (YFF) package, supporting 2 V to 5.5 V input and adjustable 1.2 V to 5.5 V output. It delivers up to 1200 mA at 3.3 V in step-down mode (VIN = 3.6 V–5.5 V), features automatic buck/boost transition, <50 μA quiescent current, and integrated overvoltage/overtemperature protection - deployed in battery-powered portable medical devices and handheld audio systems.
For engineers reviewing the TPS63010YFFR datasheet, TPS63010YFFR pinout, TPS63010YFFR application, or TPS63010YFFR equivalent, key selection criteria include its 2.126 mm × 1.922 mm DSBGA footprint, synchronous 4-MOSFET topology, fixed 2.4 MHz switching frequency (±10%), power-save mode enablement via PS pin, and support for seamless voltage regulation across input voltages crossing the output setpoint.
Technical Context
The TPS63010YFFR implements an average-current-mode, fixed-frequency PWM controller with synchronous rectification using four internal N-channel MOSFETs - one active, one rectifying, one permanently on, and one permanently off - minimizing switching losses and enabling >96% peak efficiency. Its dual-ground architecture (GND for control logic, PGND for power switches) isolates noise-sensitive circuitry while maintaining stable regulation during buck-to-boost transitions.
Operation is governed by real-time monitoring of VIN, VOUT, and inductor current: the device automatically shifts between buck and boost modes without discontinuity when VIN crosses the regulated output voltage. Feedback is closed via external resistor divider on FB (for TPS63010), while internal trimming enables fixed-output variants (TPS63011/TPS63012); undervoltage lockout (1.5–1.8 V on VINA) and overvoltage protection (6.5 V clamp) ensure robust fault handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Synchronous 4-switch buck-boost - enables continuous regulation across VIN < VOUT and VIN > VOUT without mode-hopping artifacts. |
| Input Voltage Range | 2 V to 5.5 V - supports single-cell Li-ion (2.5–4.2 V), two/three-cell alkaline/NiMH (2.0–4.5 V), and USB-powered systems. |
| Output Voltage | Adjustable 1.2 V to 5.5 V via FB pin - requires external resistor divider; no internal DAC or digital interface. |
| Max Output Current | 1200 mA at 3.3 V (VIN ≥ 3.6 V) - limited by 2.2 A typical switch current limit and thermal design in YFF package. |
| Switching Frequency | 2.4 MHz (typical), ±10% - fixed-frequency operation reduces EMI filtering burden; supports external synchronization via SYNC pin. |
| Quiescent Current | <50 μA in shutdown, 1–2 μA in light-load power-save mode - extends battery runtime in always-on sensor nodes. |
| Protection Features | Output overvoltage clamp (6.5 V), overtemperature shutdown (140 °C), undervoltage lockout (1.5–1.8 V on VINA) - autonomous fault recovery without host intervention. |
Pinout & Package
TPS63010YFFR is housed in a 20-pin DSBGA (Die Size Ball Grid Array) package measuring 2.126 mm × 1.922 mm, with 0.4 mm ball pitch and bottom-side solder balls. The package supports tape-and-reel delivery (R suffix) for automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control: drives internal bias circuits; ties to VIN for always-on operation or microcontroller GPIO for sequencing. |
| FB | Feedback input | Connects to external resistor divider for output voltage programming; internal 500 mV reference sets VOUT = 500 mV × (1 + R1/R2). |
| GND | Control ground | Reference for all analog/digital control circuitry; must be connected to PGND at single point near IC to avoid ground bounce. |
| L1 / L2 | Inductor connections | Dual inductor terminals - L1 connects to high-side switch source, L2 to low-side switch drain; requires 1.5 µH shielded inductor. |
| PGND | Power ground | Return path for high-current switch paths; separate from GND to isolate power noise from sensitive control loops. |
| PS | Power-save mode control | Low = enable power-save (pulse-skipping at light load); high = forced PWM (fixed frequency, lower light-load efficiency). |
| SYNC | External clock input | Accepts 2.2–3.0 MHz external clock for EMI reduction or multi-phase synchronization; tie to GND if unused. |
| VIN | Main power input | Supplies power stage (high-/low-side switches); accepts 2–5.5 V; decoupled with 10 µF ceramic capacitor. |
| VINA | Analog supply input | Supplies control circuitry; must be ≥1.5 V to exit UVLO; decoupled separately from VIN for noise immunity. |
| VOUT | Regulated output | Delivers regulated voltage to load; requires 10 µF output capacitance; provides feedback path for fixed-output versions. |
| VSEL | Output voltage select | Not used in TPS63010 (adjustable version); tied high/low only in TPS63011/TPS63012 fixed-output variants. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamless, discontinuity-free regulation as VIN crosses VOUT - eliminates output glitches during battery discharge in portable systems. |
| Synchronous 4-MOSFET architecture | Eliminates external diodes and reduces conduction loss; RMS current minimization extends efficiency across full load range. |
| Power-save mode (PS pin controllable) | Enables pulse-skipping below ~300 mA load - maintains >85% efficiency at 1 mA output, critical for IoT sleep-state operation. |
| Integrated overvoltage protection | Clamps VOUT to 6.5 V independent of FB connection - safeguards downstream 3.3 V/5 V logic during feedback fault or open-divider failure. |
| Dual-ground separation (GND/PGND) | Prevents high di/dt power-switch noise from corrupting control-loop references - improves stability with minimal PCB layout effort. |

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 2.8 V / 3.3 V outputs selectable via VSEL; no FB pin required; identical package and pinout. | Eliminates external resistor divider but lacks output adjustability - suitable for cost-sensitive, fixed-rail designs. | Select TPS63011YFFR when 3.3 V or 2.8 V is sufficient and board space for feedback resistors must be minimized. |
| MAX77827BEWL+T | 2.5 V–5.5 V input, 2.5 V–5.2 V adjustable output; 2.1 MHz switching; 1.2 A max; WLP-20 package (2.13 mm × 1.93 mm). | Lower quiescent current (8 μA), but no power-save mode disable option and no SYNC pin - less flexible for EMI-critical designs. | Choose MAX77827BEWL+T when ultra-low IQ dominates requirements and fixed-frequency sync is unnecessary. |
Compared with TPS63010YFFR, TPS63011YFFR removes design flexibility for output adjustment but simplifies BOM and layout, while MAX77827BEWL+T trades programmable mode control for lower static current - making TPS63010YFFR optimal for applications needing both adaptability and robust transient response.

FAQ
What is the recommended inductor value for TPS63010YFFR?
The TPS63010YFFR datasheet specifies a 1.5 µH shielded power inductor with saturation current ≥2.5 A. This value balances ripple current, size, and efficiency across the 2–5.5 V input range. Using a different inductance alters loop stability and peak switch current - deviating from 1.5 µH requires re-evaluation of compensation and thermal performance in the final layout. Always verify inductor DCR and saturation behavior under worst-case load conditions for TPS63010YFFR.
Does TPS63010YFFR require external components for basic operation?
Yes - TPS63010YFFR requires at minimum: two 10 µF X5R/X7R ceramic capacitors (input and output), a 1.5 µH shielded inductor, and a resistor divider on FB to set the output voltage. The FB divider ratio determines VOUT = 0.5 V × (1 + R1/R2). Additional components like RC filters on VINA or SYNC may be needed for noise-sensitive or synchronized systems. No external MOSFETs or diodes are required due to full integration in TPS63010YFFR.
How does the power-save mode affect efficiency at light loads in TPS63010YFFR?
With PS pin pulled low, TPS63010YFFR enters power-save mode and skips switching cycles when load current drops below ~300 mA, reducing switching losses and maintaining >85% efficiency down to 1 mA output. In contrast, forcing PWM mode (PS high) sustains fixed 2.4 MHz operation but drops to ~40% efficiency at 1 mA. This makes power-save essential for battery longevity in intermittently active applications using TPS63010YFFR.
Can TPS63010YFFR operate with input voltage below 2 V?
No - the absolute minimum input voltage for TPS63010YFFR is 2 V per Absolute Maximum Ratings, and recommended start-up begins at 2.1 V on VIN/VINA. Below 2 V, the device remains in undervoltage lockout (UVLO) and will not regulate. Attempting operation below this threshold risks unregulated output or latch-up. For sub-2 V inputs, consider dedicated low-VIN boost converters or energy-harvesting PMICs instead of TPS63010YFFR.
Is TPS63010YFFR pin-compatible with TPS63011YFFR or TPS63012YFFR?
Yes - TPS63010YFFR, TPS63011YFFR, and TPS63012YFFR share identical 20-pin DSBGA (YFF) packaging, mechanical footprint, and pinout. The only functional difference is that TPS63010YFFR uses FB for adjustable output, while TPS63011/TPS63012 replace FB functionality with VSEL-based fixed outputs. This allows direct substitution in layouts where output voltage is fixed and VSEL is appropriately biased - confirming compatibility for TPS63010YFFR drop-in replacement scenarios.
