Product details
Overview
TPS63027YFFT from Texas Instruments is a high-efficiency, synchronous single-inductor buck-boost DC/DC converter in a 25-pin WCSP (2.1 mm × 2.1 mm). It operates across 2.3 V–5.5 V input and delivers up to 5.5 V / 2 A output with automatic buck/boost mode transition, 2.5 MHz switching frequency, and 35 µA quiescent current - ideal for space-constrained battery-powered mobile devices.
For engineers reviewing the TPS63027YFFT datasheet, TPS63027YFFT pinout, TPS63027YFFT application, or TPS63027YFFT equivalent, key selection considerations include seamless mode transition behavior, integrated soft-start and output discharge, thermal shutdown (140°C), true shutdown with load disconnect, and WCSP package layout constraints for high-current inductor routing.
Technical Context
The TPS63027YFFT implements average current-mode control using four internal N-channel MOSFETs, with one switch held on and one off at all times to minimize switching losses. It regulates output voltage by dynamically selecting buck or boost topology based on VIN vs. VOUT relationship - never operating all four FETs simultaneously.
It supports dual power modes: forced PWM (via MODE pin low) at fixed 2.5 MHz, and Power Save Mode (MODE pin high) with variable-frequency PFM operation below ~350 mA load. Feedback regulation targets 0.8 V at FB pin, enabling adjustable output via external resistor divider.
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 portable systems without pre-regulation. |
| Output Voltage Range | 1.0 V to 5.5 V - programmable via FB pin; fixed versions available, but TPS63027YFFT is adjustable. |
| Max Continuous Output Current | 2 A at VIN ≥ 2.5 V, VOUT = 3.3 V - sufficient for core logic rails in smartphones and tablets. |
| Switching Frequency | 2.5 MHz typical - enables use of compact 1 µH inductors and small ceramic capacitors for minimal PCB footprint. |
| Quiescent Current | 35 µA in PFM mode - extends battery runtime in always-on or low-power standby states. |
| Efficiency | Up to 96% - achieved via synchronous rectification and optimized gate drive, critical for thermal management in sealed enclosures. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor heatsinking in compact WCSP layouts. |
Pinout & Package
TPS63027YFFT uses a 25-pin DSBGA (WCSP) package measuring 2.1 mm × 2.1 mm with 0.4 mm pitch. The package features dedicated power and analog ground pins (GND and AGND), dual inductor connections (L1/L2), and multiple parallel VIN/AVIN/VOUT pins to reduce trace resistance and inductance for high-current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (A1–A4) | Power stage input supply | Carries high pulsed input current; requires low-impedance connection to input capacitor and battery path. |
| AVIN (A5) | Analog control supply | Powers bias circuitry and feedback loop; must be decoupled separately from VIN to avoid noise coupling. |
| L1 (B1–B4) | Inductor connection (buck path) | Connects to one terminal of 1 µH inductor; shares current path with high-side buck FET. |
| L2 (D1–D4) | Inductor connection (boost path) | Connects to opposite inductor terminal; carries bidirectional current during boost/buck transitions. |
| VOUT (E1–E4) | Regulated output node | Delivers up to 2 A; multiple pins reduce IR drop and improve thermal spreading to PCB copper. |
| FB (E5) | Feedback voltage sense | Monitors output via resistor divider; 0.8 V reference enables precise output programming (e.g., 3.3 V with 510kΩ/150kΩ). |
| EN (B5) | Enable control input | Active-high logic; must be pulled high to operate; drives device into true shutdown with load disconnect and <2 µA drain. |
| MODE (C4) | PFM/PWM mode select | High = Power Save Mode (variable frequency); Low = forced PWM (2.5 MHz fixed); not floating. |
| GND (C1–C3) | Power ground return | Low-impedance return for switching currents; must connect to thermal pad and bulk capacitance ground plane. |
| AGND (C5, D5) | Analog ground reference | Reference for FB, error amplifier, and control logic; connects to GND at single point near AGND pin to prevent ground shift. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Buck-Boost Transition | Seamlessly switches between topologies as VIN crosses VOUT - no output glitch or regulation loss during battery discharge. |
| Integrated Soft-Start | 450 µs (buck) / 700 µs (boost) controlled ramp prevents inrush current and output overshoot into large capacitive loads. |
| Output Capacitor Discharge | 120 Ω internal discharge path activates on shutdown - discharges 20 µF output cap from 3.3 V to UVLO in <10 ms. |
| True Shutdown Function | Disconnects load from input during EN = low - reduces system standby current to sub-µA levels. |
| Over-Temperature Protection | Thermal shutdown at 140°C with 20°C hysteresis ensures safe recovery after transient overloads without latch-up. |
Applications
| Smartphone Core Rail | Tablet PMIC Sub-Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS630250YFFT | Same 25-pin WCSP package, 2.5 MHz, but rated for 1.5 A continuous output (vs. 2 A); lower RDS(on) in boost mode (28 mΩ). | Suitable for lower-current applications like wearables or sensors where 1.5 A suffices; slightly better light-load efficiency. | Select TPS630250YFFT only if output current requirement ≤1.5 A and board layout re-use is prioritized. |
| MAX77827BEWI+T | 2.2 MHz, 2.5 A output, WLP-20 package (2.15 mm × 1.72 mm); lacks integrated output discharge and has higher 60 µA IQ. | Better suited for designs requiring higher peak current headroom and tighter height tolerance; no built-in discharge function requires external circuitry. | Choose MAX77827BEWI+T when >2 A peak load or sub-0.5 mm Z-height is mandatory, accepting added complexity for discharge control. |
Compared with TPS63027YFFT, TPS630250YFFT offers identical footprint and control features but reduced current capability, while MAX77827BEWI+T trades integrated discharge and lower IQ for higher current and marginally smaller package - making TPS63027YFFT optimal for 2 A, space-constrained, battery-sensitive designs requiring full protection integration.

FAQ
What is the recommended inductor value for TPS63027YFFT in a 3.3 V output design?
The recommended inductor value for TPS63027YFFT in a 3.3 V output application is 1 µH, such as Coilcraft XAL4020-102MEB. This value balances efficiency, transient response, and physical size - supporting 2 A output while enabling use of compact 2.1 mm × 2.1 mm WCSP layout. Inductor saturation current must exceed 4.5 A to handle peak switch currents.
Does TPS63027YFFT require external compensation components?
No, TPS63027YFFT does not require external compensation components. Its average current-mode control architecture and internal compensation network are fully integrated, allowing stable operation with standard 1 µH inductors and 2×22 µF output capacitors without additional RC networks or type-II/III compensators.
How does the MODE pin affect TPS63027YFFT efficiency at light loads?
When the MODE pin is high, TPS63027YFFT enters Power Save Mode and reduces switching frequency dynamically, lowering quiescent current to 35 µA and maintaining >85% efficiency at 100 µA load. With MODE low, it forces fixed 2.5 MHz PWM operation, increasing light-load IQ to ~70 µA but eliminating PFM ripple.
Can TPS63027YFFT safely operate with only a 10 µF input capacitor?
Yes, TPS63027YFFT can safely operate with a minimum 10 µF X5R/X7R ceramic input capacitor placed close to VIN and GND pins. This value meets TI's recommendation for line transient suppression and EMI control; larger values (e.g., 22–47 µF) further improve stability under dynamic load steps but are not required for basic functionality.
What is the maximum output capacitance supported by TPS63027YFFT?
TPS63027YFFT supports unlimited output capacitance - no upper limit is specified. Larger output capacitors (e.g., 100 µF+) reduce output voltage ripple and improve load transient response, though soft-start time increases proportionally. The device's integrated soft-start and current limiting ensure reliable startup even with 100+ µF total COUT.
