Product details
Overview
TPS63024YFFT from Texas Instruments is a high-efficiency, single-inductor buck-boost DC/DC converter in a 20-pin WCSP package (1.766 mm × 2.086 mm), supporting 2.3 V to 5.5 V input and delivering up to 1.5 A continuous output at 3.3 V. It features automatic buck/boost mode transition, 2.5 MHz fixed-frequency PWM operation, and 35 µA quiescent current - enabling stable power regulation in battery-powered portable electronics with dynamic voltage requirements.
For engineers reviewing the TPS63024YFFT datasheet, TPS63024YFFT pinout, TPS63024YFFT application, or TPS63024YFFT equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternatives, and supply-ready availability details - all grounded in TI's production-grade SLVSCK8A datasheet (December 2014).
Technical Context
The TPS63024YFFT implements average current-mode control using four internal N-channel MOSFETs, operating exclusively in either buck or boost topology - never both simultaneously - with one switch held on and one off to minimize switching losses. Seamless mode transition occurs when VIN approaches VOUT, enforcing strict cycle sequencing (no more than three consecutive cycles in same mode) for stability.
It integrates dual supply rails (VIN for power stage, VINA for control logic) and segregated grounds (PGND for high-current paths, GND for analog reference), requiring single-point PCB connection near GND. The PFM/PWM pin enables user-selectable light-load operation: forced PWM (2.5 MHz) or automatic Power Save Mode with variable frequency and ±1.3% dynamic voltage positioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports Li-ion, Li-poly, and multi-cell alkaline inputs without external pre-regulation. |
| Output Current | 1.5 A continuous at 3.3 V (VIN ≥ 2.5 V) - sufficient for SoC core rails or display bias in compact handhelds. |
| Efficiency | Up to 95% in buck/boost modes; 97% at VIN = VOUT - reduces thermal load and extends battery runtime. |
| Switching Frequency | 2.5 MHz typical - enables use of small 1 µH inductors and 22 µF ceramic output capacitors for space-constrained layouts. |
| Quiescent Current | 35 µA (typical) - maintains ultra-low standby power in always-on subsystems like RTC or sensor hubs. |
| Feedback Voltage | 0.8 V (fixed reference) - allows precise output setting via external resistor divider; compatible with 2.5–3.6 V adjustable range. |
| Thermal Shutdown | 140 °C junction temperature - protects against sustained overload or poor PCB thermal design without latch-up. |
| Shutdown Current | 0.1–2 µA - isolates load from battery during system sleep, preventing parasitic drain. |
Pinout & Package
TPS63024YFFT uses a 20-pin DSBGA (WCSP) package measuring 1.766 mm × 2.086 mm, optimized for ultra-thin mobile applications. Pin mapping follows TI's YFF top-view layout with dedicated power and signal terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (E1–E3) | Power Input | Main supply rail for power stage; accepts 2.3–5.5 V; must be decoupled near package. |
| VINA (E4) | Control Supply | Dedicated low-noise input for analog control circuitry; improves PSRR and transient immunity. |
| VOUT (A1–A3) | Regulated Output | High-current output node; connects directly to load and output capacitor bank (e.g., 2×22 µF). |
| FB (A4) | Feedback Input | Senses output voltage via resistor divider; tied to VOUT for fixed-output variants like TPS630242. |
| L1 (D1–D3) | Inductor Terminal | Connects to one end of series inductor; carries full switched current in buck mode. |
| L2 (B1–B3) | Inductor Terminal | Connects to other inductor end; carries full switched current in boost mode. |
| EN (D4) | Enable Control | Active-high digital enable; asserts soft-start and disconnects load in shutdown (120 Ω discharge path). |
| PFM/PWM (B4) | Mode Select | Forces PWM (high) or enables auto PFM (low); critical for optimizing efficiency across load range. |
| PGND (C1–C3) | Power Ground | High-current return path for switches and inductors; must be low-impedance plane under IC. |
| GND (C4) | Analog Ground | Reference for FB, EN, PFM/PWM; connected to PGND at single point near GND pin only. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Buck-Boost Transition | Seamless mode switching at VIN ≈ VOUT eliminates output glitches and simplifies system-level voltage management. |
| 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 ensures <10 ms discharge of 20 µF at 3.3 V - meets safety requirements for hot-plug systems. |
| Over-Temperature Protection | 140 °C thermal shutdown with hysteresis prevents damage during sustained overload or poor heatsinking. |
| True Shutdown Function | Load isolation from input during EN = low; zero reverse current path preserves battery charge integrity. |
| Wide Capacitance Support | Validated with 16–100 µF ceramic output caps - accommodates aging, DC bias, and ESR variations across vendors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS630242YFFT | Fixed 3.3 V output (vs. adjustable TPS63024YFFT); identical package, pinout, and electrical specs except FB pin tied internally. | Eliminates external resistor divider; suited for cost-sensitive designs with fixed VOUT requirement. | Select TPS630242YFFT when 3.3 V is mandatory and board space for feedback resistors is constrained. |
| TPS63031YFFT | Lower 1 A output current rating; 3.2 MHz switching frequency; 2.5 V to 5.5 V input; shares WCSP-20 package but different pin functions (e.g., no VINA pin). | Targeted at lower-power wearables; lacks VINA separation and thermal performance margin of TPS63024YFFT. | Choose TPS63031YFFT only if load current stays ≤1 A and thermal headroom is sufficient for ambient conditions. |
Compared with TPS630242YFFT, the TPS63024YFFT offers design flexibility via external feedback while retaining identical footprint and reliability; versus TPS63031YFFT, it provides +50% output current headroom, dedicated VINA rail, and superior thermal robustness - critical for sustained 1.5 A operation in thermally limited enclosures.

FAQ
What is the maximum continuous output current supported by the TPS63024YFFT?
The TPS63024YFFT delivers up to 1.5 A continuous output current at 3.3 V when input voltage is ≥2.5 V. This rating holds across the full operating temperature range (–40 °C to 85 °C ambient) and is validated under typical 2.5 MHz PWM operation with proper thermal layout. Peak switch current is limited to 3 A average, making it suitable for demanding portable loads like application processors and display drivers.
Does the TPS63024YFFT require an external resistor divider for output voltage setting?
Yes - the TPS63024YFFT is the adjustable-output variant and requires an external resistor divider connected between VOUT and FB to set the desired output voltage within the 2.5 V to 3.6 V range. The internal 0.8 V feedback reference enables precise programming; for fixed 3.3 V operation, TI recommends the pin-compatible TPS630242YFFT, which ties FB internally and eliminates external components.
How does the PFM/PWM pin affect efficiency and output ripple in the TPS63024YFFT?
When the PFM/PWM pin is pulled low, the TPS63024YFFT enters Power Save Mode below ~350 mA load, reducing switching frequency and quiescent current to maintain >85% efficiency at light loads - but increases output ripple to ~30 mVpk-pk (up to 50 mVpk-pk). Pulling the pin high forces fixed 2.5 MHz PWM operation, minimizing ripple (<10 mVpk-pk) at the cost of higher light-load current draw.
Can the TPS63024YFFT safely operate with a single 1 µH inductor?
Yes - the TPS63024YFFT is fully characterized with a 1 µH inductor (e.g., Coilcraft XAL4020-102ME), supporting its 2.5 MHz switching frequency and 1.5 A output. TI's datasheet specifies 0.5–1.3 µH as the recommended range; 1 µH balances ripple current, efficiency, transient response, and physical size. Inductor saturation current must exceed 4.5 A to handle peak currents in boost mode at minimum VIN.
What thermal considerations apply to the TPS63024YFFT in a compact PCB layout?
The TPS63024YFFT has a junction-to-ambient thermal resistance (RθJA) of 53.8 °C/W in the YFF WCSP package. To maintain safe operation at 1.5 A continuous load, ensure ≥400 mm² of 1-oz copper connected to PGND pins, avoid enclosing the IC, and limit ambient temperature to ≤60 °C. Thermal shutdown triggers at 140 °C junction, but sustained operation above 125 °C degrades long-term reliability.
