Product details
Overview
TPS63024YFFR from Texas Instruments is a high-efficiency, single-inductor buck-boost DC/DC converter optimized for battery-powered systems where input voltage may fall above or below the regulated output. It delivers up to 1.5A continuous output current at 3.3V with 2.3V–5.5V input range, 95% peak efficiency in buck/boost modes, and seamless automatic mode transition. It is used in smartphone power rails requiring stable 3.3V supply from Li-ion or multi-cell batteries.
For engineers reviewing the TPS63024YFFR datasheet, TPS63024YFFR pinout, TPS63024YFFR application, or TPS63024YFFR equivalent, this page provides verified technical context, validated pin functions, confirmed operating parameters (including 2.5MHz switching frequency, 35μA quiescent current, and integrated soft-start), and real-world application constraints for portable electronics power design.
Technical Context
The TPS63024YFFR implements average current-mode control using four internal N-channel MOSFETs, operating exclusively in either buck or boost topology-never both simultaneously-to minimize switching losses. It maintains regulation by dynamically selecting mode based on VIN vs VOUT, with one switch held on and one off during each phase.
Its dual-supply architecture separates power (VIN, PGND) and control (VINA, GND) paths to prevent ground shift under high-current transients. The PFM/PWM pin enables user-selectable light-load operation: forced PWM (2.5MHz fixed frequency) or automatic Power Save Mode with variable-frequency pulse bursting and dynamic voltage positioning (1.3% overregulation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3V to 5.5V - supports single-cell Li-ion (2.7–4.2V), Li-polymer, or two-cell alkaline inputs without external pre-regulation. |
| Output Current | 1.5A continuous at 3.3V - sufficient for baseband processors, RF transceivers, and display drivers in compact mobile devices. |
| Peak Efficiency | 95% in buck or boost mode - reduces thermal load and extends battery runtime in portable applications. |
| Switching Frequency | 2.5MHz typical - enables use of small 1µH inductors and compact 0603 ceramic capacitors for space-constrained PCB layouts. |
| Quiescent Current | 35μA - minimizes standby power loss in always-on subsystems such as touch controllers or sensors. |
| Feedback Reference | 0.8V - allows precise output adjustment via external resistor divider; fixed 3.3V version (TPS630242) uses internal reference. |
| Thermal Shutdown | 140°C junction temperature - protects device during sustained overload or poor thermal management without latch-up. |
| Soft-Start Time | 450µs (buck), 700µs (boost) - limits inrush current into large output capacitance while preventing output overshoot. |
Pinout & Package
TPS63024YFFR is housed in a 20-pin DSBGA (WCSP) package measuring 1.766 mm × 2.086 mm with 0.4-mm pitch, optimized for ultra-thin mobile PCBs and requiring microvia-in-pad assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (E1–E3) | Power Input | Primary power rail for high-current switching stage; must be decoupled with ≥10µF low-ESR ceramic capacitor near package. |
| VINA (E4) | Control Supply | Dedicated low-noise supply for analog control circuitry; separate from VIN to avoid noise coupling into feedback loop. |
| VOUT (A1–A3) | Regulated Output | Delivers regulated 3.3V (or adjustable) to load; connects directly to output capacitor bank and downstream ICs. |
| FB (A4) | Feedback Input | Monitors output via resistor divider; tied internally to VOUT for fixed-output variants like TPS630242. |
| L1 (D1–D3), L2 (B1–B3) | Inductor Connections | Two dedicated high-current terminals for single inductor; requires symmetric layout to balance current paths and minimize EMI. |
| PGND (C1–C3) | Power Ground | Return path for switching currents; must be connected to solid ground plane with minimal impedance and short traces. |
| GND (C4) | Analog Ground | Reference for control logic and feedback amplifier; joined to PGND at single point near GND pin to avoid ground bounce. |
| EN (D4) | Enable Input | Active-high digital control; drives device into true shutdown (<2μA ISD) and disconnects load from input. |
| PFM/PWM (B4) | Mode Control | Selects between automatic PFM (light load) or forced PWM (fixed 2.5MHz); must not float - tie to GND or VIN via resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Buck-Boost Transition | Seamless mode switching at VIN ≈ VOUT eliminates output discontinuity and audible artifacts during battery discharge. |
| Integrated Output Discharge | 120Ω internal discharge path activates on EN low, discharging 20µF output cap to UVLO threshold in <10ms - prevents residual voltage hazards. |
| True Shutdown Function | Load isolation achieved via internal high-side switch; ensures zero current draw from battery when disabled - critical for long-term storage. |
| Over-Temperature Protection | Hysteresis-free thermal shutdown at 140°C junction temperature with automatic recovery after cooling - avoids system lockup. |
| Wide Capacitance Compatibility | Supports 16µF minimum output capacitance with standard X5R/X7R ceramics - accommodates aging, bias, and temperature derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS630242YFFR | Fixed 3.3V output; no external feedback resistors required; identical pinout and package. | Eliminates external resistor network - simplifies layout and reduces component count for fixed-voltage designs. | Choose TPS630242YFFR if 3.3V output is fixed and board space is constrained; TPS63024YFFR retains adjustability for future voltage revisions. |
| MAX77827BEWL+T | 2.5V–5.5V input, 1.8V–5.2V adjustable output, 2A max, 2MHz switching, 20-pin WLP package. | Higher output current capability and wider VOUT range; lacks integrated output discharge and has higher 50μA IQ. | Prefer MAX77827BEWL+T for designs needing >1.5A or programmable outputs beyond 3.3V; TPS63024YFFR offers superior light-load efficiency and smaller footprint. |
Compared with TPS630242YFFR, the TPS63024YFFR provides design flexibility through external feedback while sharing identical thermal performance and package. Against MAX77827BEWL+T, it trades peak current headroom for lower quiescent power and tighter integration - making it optimal for space- and battery-life-critical portable systems.

FAQ
What is the maximum continuous output current of the TPS63024YFFR?
The TPS63024YFFR delivers up to 1.5A continuous output current at 3.3V when VIN ≥ 2.5V. In buck mode (VIN > VOUT), it supports up to 3A peak switch current, but average output remains limited to 1.5A due to thermal and package constraints. This rating is validated across –40°C to 85°C ambient with proper PCB thermal design per datasheet guidelines.
Does the TPS63024YFFR require external components for basic operation?
Yes, the TPS63024YFFR requires an external 1µH inductor (L1/L2), input capacitor (≥10µF), output capacitor (≥16µF), and feedback resistors (for adjustable versions). The TPS63024YFFR datasheet specifies exact values and placement rules - e.g., 2×22µF output caps in parallel and 0.4-mm-pitch WCSP layout - to ensure stability, efficiency, and EMI compliance.
How does the PFM/PWM pin affect TPS63024YFFR operation?
The PFM/PWM pin on the TPS63024YFFR selects between automatic light-load PFM mode (pin low) and forced fixed-frequency PWM mode (pin high). In PFM mode, the TPS63024YFFR reduces switching frequency and supply current to maintain >85% efficiency down to 100µA load. In PWM mode, it operates at 2.5MHz regardless of load, minimizing output ripple for noise-sensitive circuits.
Can the TPS63024YFFR be used with a single-cell Li-ion battery?
Yes, the TPS63024YFFR is explicitly designed for single-cell Li-ion (2.7V–4.2V) and Li-polymer batteries. Its 2.3V–5.5V input range covers full discharge including protection cutoff (~2.8V), and its automatic buck-boost transition ensures uninterrupted 3.3V output even as battery voltage drops below the regulated rail - a key requirement for reliable smartphone and wearable operation.
What thermal performance can be expected from the TPS63024YFFR in a typical layout?
In a standard 4-layer PCB with 1-in² 2-oz copper thermal pad connected to internal ground planes, the TPS63024YFFR achieves a junction-to-ambient thermal resistance (RθJA) of 53.8°C/W. At 1.5A output and 3.6V input, this results in ~35°C junction rise above ambient - well within the 125°C max rating. The TPS63024YFFR includes thermal shutdown at 140°C for fault protection.
