Product details
Overview
TPS62625YFFT from Texas Instruments is a 6-MHz synchronous step-down DC/DC converter in a 6-pin NanoFree™ WCSP package, delivering 1.2 V fixed output at up to 600 mA load current with 90% peak efficiency, 31 μA quiescent current, and ±2% total DC voltage accuracy - optimized for Li-ion–powered mobile phones and Bluetooth/WLAN subsystems.
For engineers reviewing the TPS62625YFFT datasheet, TPS62625YFFT pinout, TPS62625YFFT application, or TPS62625YFFT equivalent, key selection criteria include its regulated 6-MHz switching frequency, automatic PFM/PWM mode switching, 2.3 V to 5.5 V input range, integrated soft-start (120-μs startup), and ultra-low 1.30 mm × 0.96 mm footprint for space-constrained portable designs.
Technical Context
The TPS62625YFFT uses a frequency-locked ring-oscillating modulator architecture with no traditional feedback loop, enabling instantaneous transient response and inherent stability across L/COUT variations. It integrates P-channel and N-channel MOSFETs with RDS(on) of 640 mΩ (P) and 200 mΩ (N) at 2.5 V GS, and features undervoltage lockout (2.05 V threshold) and thermal shutdown (140°C).
Its MODE pin selects between auto PFM/PWM operation (MODE = low) or forced PWM (MODE = high) for noise-sensitive applications, while EN enables/disables the device with 0.2 μA shutdown current. The FB pin senses output voltage via an internal 0.8-V reference, and SW drives the external inductor with discontinuous conduction mode (DCM) during light-load PFM operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports full Li-ion battery discharge curve without brownout. |
| Output Voltage | Fixed 1.2 V - internally trimmed, ±2% total DC accuracy over line/load/temperature. |
| Max Output Current | 600 mA - sustained delivery with thermal shutdown protection at 140°C junction temp. |
| Switching Frequency | 6 MHz (±10%) - fixed-frequency PWM mode; PFM mode varies frequency at light loads. |
| Quiescent Current | 31 μA - enables >1000-hour standby in always-on sensor nodes or Bluetooth LE devices. |
| Efficiency (Typ) | 90% at 6 MHz, 1.2 V/100 mA, VIN = 3.6 V - minimizes heat in sealed handheld enclosures. |
| Startup Time | 120 μs - internal soft-start prevents input rail sag during power-up from weak sources. |
Pinout & Package
TPS62625YFFT is housed in a 6-pin DSBGA (NanoFree™ WCSP) package measuring 1.30 mm × 0.96 mm with 0.5-mm pitch and bottom-side solder balls. The package supports sub-1-mm profile PCB layouts and requires no external compensation components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.3–5.5 V; connects to battery or PMIC output; decoupled with 2.2-μF MLCC. |
| SW | Switch node | Drives external 0.47-μH inductor; high dv/dt node requiring tight layout and ground guard ring. |
| FB | Feedback input | Senses regulated 1.2 V output via internal 0.8-V reference; no external resistor divider needed. |
| MODE | Mode control | Pull low for auto PFM/PWM; pull high for forced PWM - critical for EMI filtering in RF sections. |
| EN | Enable input | Active-high logic; <0.4 V disables device, reducing IQ to 0.2 μA; must not float. |
| GND | Ground reference | System ground return; connects directly to thermal pad under die for optimal θJB = 22°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM/PWM transition | Maintains >85% efficiency from 10 μA to 600 mA load without manual mode control. |
| Low-ripple PFM mode | Delivers <24 mVPP ripple at 1 mA load - suitable for noise-sensitive analog/RF rails. |
| Integrated soft-start | 120-μs controlled ramp prevents inrush current into 4.7-μF output capacitor. |
| Thermal & overload protection | Shuts down at 140°C junction temp and limits P-MOS current to 1.1 A nominal. |
| Ultra-compact solution | Total BOM: 1 inductor + 2 MLCCs; solution size <12 mm² - fits beneath smartphone camera modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62621YFFT | Fixed 1.8 V output; same 6-MHz operation, 31 μA IQ, and WCSP package. | Targets 1.8-V I/O rails (e.g., SDIO, UART) instead of 1.2-V core logic. | Select when system requires 1.8 V with identical size/power envelope. |
| TPS62085RRT | 3-MHz switching, 1.2 V/1.2 A, 20 μA IQ, 9-ball WSON package (1.5 × 1.5 mm). | Higher current and lower IQ, but larger footprint and lower frequency - less EMI filtering burden. | Choose for higher load headroom (>600 mA) where board area permits 2.25× larger package. |
Compared with TPS62625YFFT, TPS62621YFFT offers identical performance at 1.8 V for I/O domains, while TPS62085RRT trades 6-MHz speed and ultra-small size for greater current capacity and lower quiescent current - making it suitable for next-generation wearables needing extended runtime without shrinking PCB real estate.

FAQ
What is the output voltage tolerance of the TPS62625YFFT over temperature and load?
The TPS62625YFFT delivers a fixed 1.2 V output with ±2% total DC voltage accuracy across –40°C to 85°C ambient temperature, 2.3 V to 5.5 V input, and 0 mA to 600 mA load current. This specification includes initial tolerance, line regulation (0.13%/V), load regulation (–0.0003%/mA), and thermal drift - verified per TI's SLVS848D datasheet Section 7.5.
Does the TPS62625YFFT support active output discharge?
No, the TPS62625YFFT does not include active output capacitor discharge functionality. That feature is exclusive to the TPS62624 variant (part number suffix YFFR), which integrates a 15-Ω internal discharge resistor. The TPS62625YFFT enters high-impedance shutdown when disabled, leaving the output voltage to decay naturally through the load.
What inductor value is recommended for optimal performance with the TPS62625YFFT?
Texas Instruments specifies 0.47 μH as the optimized inductor value for the TPS62625YFFT, paired with a 4.7-μF output capacitor. This combination achieves stable operation, minimal output ripple, and best-in-class transient response. Inductors in the 0.3–1.3 μH range are supported, but deviation affects PFM/PWM transition point and efficiency - see TI Application Report SLVA438 for stability analysis.
Can the TPS62625YFFT operate with a 2.0-V input supply?
No, the TPS62625YFFT cannot operate reliably at 2.0 V input. Its undervoltage lockout (UVLO) threshold is 2.05 V (typical), with full functionality specified only above 2.1 V. Below this, the device remains latched off. For systems requiring operation down to 2.0 V, consider the TPS62865 or other TI buck converters with lower UVLO.
Is the TPS62625YFFT pin-compatible with other members of the TPS6262x family?
Yes, all TPS6262x variants - including TPS62620YFFT through TPS62625YFFT - share identical 6-pin DSBGA (YFF) packaging, pinout, and footprint. They differ only in fixed output voltage (1.2 V to 1.82 V) and optional features (e.g., discharge function in TPS62624). This allows direct substitution in layout without PCB revision when changing output voltage requirements.
