Product details
Overview
TPS62625YFFR from Texas Instruments is a 600-mA, 6-MHz synchronous step-down DC/DC converter in a 6-pin NanoFree™ WCSP package, optimized for Li-ion–powered portable devices. It delivers fixed 1.2 V output with ±2% DC accuracy, 31 μA quiescent current in PFM mode, and supports 2.3 V to 5.5 V input-enabling use in smartphone core-rail power supplies.
For engineers reviewing the TPS62625YFFR datasheet, TPS62625YFFR pinout, TPS62625YFFR application, or TPS62625YFFR equivalent, key selection criteria include its automatic PFM/PWM mode switching, 120-μs soft-start time, integrated thermal shutdown, 90% peak efficiency at 6 MHz, and ultra-compact <12 mm² solution size with only three external components.
Technical Context
The TPS62625YFFR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional feedback compensation while delivering best-in-class load/line transient response. Its non-linear control loop enables instantaneous VOUT correction without stability dependency on external L/C values.
It integrates dual MOSFETs (P-channel RDS(on) = 640 mΩ typ at 2.5 V, N-channel RDS(on) = 200 mΩ typ), undervoltage lockout (2.05 V threshold), and cycle-by-cycle current limiting (1.1 A nominal). Unlike TPS62624, it lacks active output capacitor discharge but shares identical pinout, package, and operating temperature range (–40°C to 85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V with ±2% total DC accuracy-ensures stable core voltage for low-power processors and RF ICs. |
| Max Output Current | 600 mA continuous-supports single-core application processors and baseband ICs in mobile handsets. |
| Switching Frequency | 6 MHz (±10%) regulated-enables use of sub-1-μH chip inductors and reduces EMI filtering burden. |
| Quiescent Current | 31 μA typical in PFM mode-extends battery runtime during standby and light-load states. |
| Input Voltage Range | 2.3 V to 5.5 V-fully covers Li-ion battery discharge curve (4.2 V → 2.7 V) plus tolerance margin. |
| Efficiency Peak | 90% at 6 MHz operation-minimizes thermal rise in space-constrained handheld enclosures. |
| Start-Up Time | 120 μs-meets fast wake-up timing requirements for always-on sensor subsystems. |
Pinout & Package
TPS62625YFFR uses a 6-pin DSBGA (NanoFree™ WCSP) package, 1.30 mm × 0.96 mm body size, 0.4-mm pitch, bottom-side solder balls. Thermal resistance: RθJA = 130°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.3–5.5 V supply; connects to battery or PMIC output; requires local 2.2-μF ceramic decoupling. |
| SW | Switch node | Drain of internal P-MOSFET and source of N-MOSFET; connects directly to inductor; high dv/dt node requiring tight layout. |
| FB | Feedback sense | High-impedance input (480 kΩ) monitoring VOUT; connected directly to output capacitor for regulation accuracy. |
| MODE | Operating mode select | Pull low for auto PFM/PWM; pull high for forced PWM-enables noise-sensitive RF section coexistence. |
| EN | Enable control | Active-high logic; drives to VIN to enable, GND to shut down (ISD = 0.2 μA typ); must not float. |
| GND | Ground reference | Power and signal return; requires low-inductance connection to PCB ground plane under device. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM transition | Maintains >85% efficiency from 10 μA to 600 mA load-no external mode control required. |
| Integrated soft start | 120-μs controlled ramp prevents inrush current and input rail droop during power-up. |
| Thermal shutdown + hysteresis | Triggers at 140°C junction temp; resumes at 130°C-prevents thermal runaway without system-level intervention. |
| Ultra-small solution footprint | Total area <12 mm² using 0.47-μH inductor and two 0402 ceramic caps-ideal for slim mobile designs. |
| Robust protection suite | Includes UVLO (2.05 V), cycle-by-cycle overcurrent limit, and short-circuit foldback-reduces need for external supervision. |
Applications
| Smartphone Application Processor Core Rail | Bluetooth Low Energy SoC Power |

IC Role / Device Role / Timing Role: System-level power manager handling deep-sleep wake-up and RF transmit bursts. Use Value: 31 μA quiescent current extends coin-cell or small Li-po battery life beyond 1 year in sensor beacon applications. |
| GPS/GLONASS Front-End LNA Bias | WLAN 2.4 GHz Transceiver I/O Rail |
Use Scenario: Generates low-noise 1.2 V bias for GPS front-end LNAs where PSRR and ripple directly impact sensitivity. IC Role / Device Role / Timing Role: Noise-sensitive analog power source; operates in forced PWM mode via MODE pin. Use Value: Fixed 6 MHz switching allows precise EMI filter placement; PFM ripple suppressed to <24 mVPP ensures <0.5 dB NF degradation. | Use Scenario: Powers WLAN transceiver I/O interface (e.g., SDIO, UART) requiring stable 1.2 V during data bursts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62621YFFR | Fixed 1.8 V output; same package, pinout, and specs except output voltage and FB divider. | Used where higher core voltage required (e.g., legacy baseband ICs); no change to PCB layout. | Select when system requires 1.8 V instead of 1.2 V-identical thermal, efficiency, and transient behavior. |
| TPS62085RRLT | 600 mA, 2.5–6 V input, 1.2 V output; 2-MHz switching; 17 μA IQ; 1.2-mm × 0.8-mm DSBGA. | Lower frequency enables larger inductors; lower IQ benefits ultra-low-power IoT nodes; different pinout and package marking. | Choose for longer battery life in always-on sensors-accept trade-off of larger magnetics and reduced transient speed. |
Compared with TPS62625YFFR, TPS62621YFFR offers identical form-factor and performance at 1.8 V, while TPS62085RRLT trades 6-MHz speed for lower quiescent current and relaxed EMI filtering-making it suitable for cost-sensitive, low-duty-cycle applications where board space permits larger passives.

FAQ
What is the output voltage tolerance of the TPS62625YFFR over temperature and line/load conditions?
The TPS62625YFFR guarantees ±2% total DC voltage accuracy across –40°C to 85°C ambient temperature, 2.3 V to 5.5 V input, and 0–600 mA load. This 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 TPS62625YFFR support forced PWM mode, and how is it enabled?
Yes, the TPS62625YFFR supports forced PWM mode. Pull the MODE pin high (≥1.0 V) to disable automatic PFM/PWM transition and maintain fixed 6-MHz operation at all loads. This reduces output ripple and simplifies EMI filtering for noise-sensitive RF sections-confirmed in Section 8.3.1 of the datasheet.
What is the recommended inductor value for optimal performance with the TPS62625YFFR?
Texas Instruments recommends a 0.47-μH inductor (e.g., Murata LQM21PNR47MC0) for the TPS62625YFFR, as the internal compensation is optimized for this value with 4.7-μF output capacitance. Inductor values between 0.3 μH and 1.3 μH are supported, but 0.47 μH balances efficiency, transient response, and solution size per Section 9.2.2.1.
How does the TPS62625YFFR handle short-circuit conditions?
The TPS62625YFFR implements cycle-by-cycle P-channel MOSFET current limiting (1.1 A nominal). During short circuit, it reduces current limit to 550 mA once VOUT falls below ~0.4 V and enters hiccup mode after sustained fault-protecting both IC and PCB traces without external components, as detailed in Section 8.4.5.
Is the TPS62625YFFR pin-compatible with other members of the TPS6262x family?
Yes, all TPS6262x variants-including TPS62625YFFR, TPS62621YFFR, and TPS62624YFFR-share identical 6-pin DSBGA (YFF) package, pinout, and footprint. Only the output voltage and presence of active discharge (TPS62624 only) differ; no PCB redesign is needed when substituting within the family.
