Product details
Overview
TPS63027YFFR from Texas Instruments is a high-efficiency, synchronous single-inductor buck-boost DC/DC converter optimized for battery-powered systems where input voltage may fall above or below regulated output. It delivers up to 2 A continuous output current at 3.5 V with 2.3 V–5.5 V input range, 1.0 V–5.5 V programmable output, and 96% peak efficiency - used in smartphone power rails, tablet PMICs, and portable accessories requiring seamless mode transition.
For engineers reviewing the TPS63027YFFR datasheet, TPS63027YFFR pinout, TPS63027YFFR application, or TPS63027YFFR equivalent, key selection criteria include its 2.5 MHz fixed-frequency PWM/Power Save Mode operation, integrated soft-start, true shutdown with output discharge, and 25-pin 2.1 mm × 2.1 mm DSBGA package enabling ultra-compact layout in space-constrained mobile designs.
Technical Context
The TPS63027YFFR implements average-current-mode control using four internal N-channel MOSFETs, operating exclusively in either buck or boost topology - never all four switches active simultaneously. It maintains regulation by dynamically selecting mode based on VIN vs VOUT, with forced PWM or automatic PFM/PWM selectable via the MODE pin.
Its dual-supply architecture separates power (VIN, GND, L1/L2) and control (AVIN, AGND) domains to minimize ground shift; feedback uses a precise 0.8 V reference at FB with ±1% accuracy in PWM mode. Thermal shutdown activates at 140°C with 20°C hysteresis, and undervoltage lockout disables operation below 1.6 V VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V), USB (4.75–5.25 V), and wide-input industrial sources without external pre-regulation. |
| Output Voltage Range | 1.0 V to 5.5 V - adjustable via external resistor divider (FB pin = 0.8 V nominal), enabling direct replacement of multiple fixed-output regulators. |
| Continuous Output Current | 2 A at VIN ≥ 2.5 V, VOUT = 3.5 V - sufficient for AP SoC core rails, display bias, or USB OTG power in handheld devices. |
| Switching Frequency | 2.5 MHz typical - enables use of small 1 µH inductors and compact ceramic capacitors, reducing solution footprint and EMI filtering complexity. |
| Quiescent Current | 35 µA in PFM mode - extends battery runtime in always-on sensor or standby subsystems without compromising wake-up response. |
| Efficiency | Up to 96% - minimizes thermal dissipation in sealed enclosures and preserves battery capacity across load range (10 mA to 2 A). |
| Package | 25-pin DSBGA (YFF), 2.1 mm × 2.1 mm - ultra-small footprint compatible with fine-pitch PCB assembly and high-density mobile PCB stacking. |
Pinout & Package
TPS63027YFFR uses a 25-pin wafer-level chip-scale package (DSBGA, YFF) measuring 2.1 mm × 2.1 mm with 0.4 mm pitch and bottom-side solder balls. Thermal performance is enhanced by dedicated GND and AGND planes and exposed thermal pad connection to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (A1–A4) | Power input supply | High-current path for main input rail; must be decoupled with ≥10 µF ceramic capacitor close to pins. |
| AVIN (A5) | Analog supply input | Dedicated low-noise supply for control circuitry; isolated from VIN to prevent switching noise coupling into regulation loop. |
| L1 (B1–B4) | Inductor connection (buck phase) | Connects to one end of 1 µH inductor; carries high di/dt current during buck operation - requires short, wide trace routing. |
| EN (B5) | Enable control input | Active-high logic input; must be pulled high (>1.2 V) to enable; floating state is undefined - requires pull-up or MCU GPIO drive. |
| GND (C1–C3) | Power ground | Return path for switch currents; must be connected to PCB ground plane with low-inductance vias near L1/L2 pins. |
| MODE (C4) | PFM/PWM mode select | High = automatic PFM/PWM transition; Low = forced PWM - used to eliminate PFM ripple in noise-sensitive analog sections. |
| AGND (C5, D5) | Analog ground reference | Reference for FB, error amplifier, and oscillator; must connect to GND at single point near AGND pin to avoid ground bounce. |
| L2 (D1–D4) | Inductor connection (boost phase) | Connects to opposite end of same 1 µH inductor; shares inductor with L1 - enables single-inductor buck-boost topology. |
| VOUT (E1–E4) | Regulated output | Delivers up to 2 A; requires ≥44 µF effective ceramic capacitance (e.g., 2×22 µF) placed adjacent to pins for stability and transient response. |
| FB (E5) | Feedback voltage input | Monitors output via resistor divider; internal 0.8 V reference sets VOUT = 0.8 × (1 + R1/R2); bias current <100 nA enables high-resistor values. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamless switching between topologies at VIN ≈ VOUT without output glitch or dropout - critical for battery voltage sag during peak load. |
| True shutdown with output discharge | Internal 120 Ω discharge FET activates when EN = low, discharging 20 µF output cap in <10 ms - prevents residual voltage from interfering with system reset sequencing. |
| Integrated soft-start | 450 µs (buck) / 700 µs (boost) monotonic ramp prevents inrush current and overshoot - eliminates need for external timing components. |
| Over-temperature and over-current protection | Thermal shutdown at 140°C (20°C hysteresis); current limit adjusts with VIN–VOUT differential - protects IC and load under fault conditions. |
| Low-noise Power Save Mode | PFM operation reduces quiescent current to 35 µA while maintaining regulation; 30 mVpp ripple at light load - suitable for always-on sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS630250YFFR | Lower 2 A max output current; identical 2.1 mm × 2.1 mm DSBGA package and pinout; 95% peak efficiency. | Targeted for cost-sensitive mid-tier smartphones with lower peak power demands. | Select when full 2 A capability is not required and BOM cost optimization is prioritized. |
| MAX77827BEWL+T | 2.5 A output; 2.2 MHz switching; different 28-pin WLP package (2.14 mm × 1.74 mm); no MODE pin for PFM/PWM control. | Designed for wearables with tighter height constraints and higher current needs than TPS63027YFFR. | Choose when >2 A output or alternate package footprint is needed, accepting loss of programmable PFM/PWM mode. |
Compared with TPS63027YFFR, TPS630250YFFR offers identical integration and layout compatibility at reduced current rating, while MAX77827BEWL+T provides higher current in a slightly larger but non-pin-compatible package - making TPS63027YFFR optimal for 2 A mobile applications demanding seamless mode transition and flexible light-load efficiency control.

FAQ
What is the recommended inductor value for TPS63027YFFR in a typical 3.5-V output design?
The recommended inductor value for TPS63027YFFR in a 3.5-V output application is 1 µH, such as Coilcraft XAL4020-102MEB (4.5 A saturation current, 13 mΩ DCR). This value balances low ripple current, high efficiency at 2.5 MHz switching, and fast transient response while fitting within the 2.1 mm × 2.1 mm board area constraint.
Does TPS63027YFFR support fixed-output voltage versions, or is it only adjustable?
TPS63027YFFR is the adjustable-output version of the device, requiring an external resistor divider on the FB pin to set VOUT. Fixed-output variants like TPS630271YFFR (3.3 V) and TPS630272YFFR (3.6 V) exist but are distinct orderable part numbers - TPS63027YFFR itself has no internal voltage reference other than the 0.8 V FB threshold.
How does the MODE pin affect TPS63027YFFR operation in light-load conditions?
When the MODE pin of TPS63027YFFR is pulled high, the device operates in automatic PFM/PWM mode, entering Power Save Mode below ~350 mA to reduce quiescent current to 35 µA. When MODE is pulled low, TPS63027YFFR forces continuous PWM operation regardless of load, eliminating PFM ripple but increasing light-load IQ to ~70 µA.
Can TPS63027YFFR safely operate with input voltage below 2.3 V?
No - TPS63027YFFR has a specified minimum input voltage of 2.3 V per recommended operating conditions. Operation below this risks UVLO activation (threshold 1.6–2.0 V), unregulated output, or failure to start. For sub-2.3 V inputs, consider TI's TPS63802 or alternative ultra-low-VIN buck-boost converters.
What thermal derating applies to TPS63027YFFR at 85°C ambient temperature?
At 85°C ambient, TPS63027YFFR maintains full 2 A output capability if PCB layout provides adequate copper area and thermal vias under the DSBGA package. Its RθJA is 62.1°C/W; with proper thermal design, junction temperature stays below 125°C even at full load - no mandatory current derating is required at 85°C ambient.
