Product details
Overview
TPS62620YFFT 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 1.82 V output with ±2% DC accuracy, 90% peak efficiency at 6 MHz, and 31 μA quiescent current in PFM mode-enabling extended battery life in smartphones and Bluetooth modules.
For engineers reviewing the TPS62620YFFT datasheet, TPS62620YFFT pinout, TPS62620YFFT application, or TPS62620YFFT equivalent, key selection criteria include its regulated 6-MHz PWM/PFM auto-switching operation, ultra-low 1.30 mm × 0.96 mm footprint, integrated soft-start (120 μs), and support for chip-scale inductor/capacitor solutions under 12 mm² total area.
Technical Context
The TPS62620YFFT employs a frequency-locked ring-oscillating modulator architecture with no traditional compensated feedback loop-enabling instantaneous transient response and inherent stability across L/COUT variations. Its non-linear control eliminates need for external compensation while maintaining fixed 6 MHz switching across 2.3–5.5 V input and 0–600 mA load range.
It integrates P-channel (270 mΩ typical) and N-channel (140 mΩ typical) MOSFETs, undervoltage lockout (2.05 V threshold), thermal shutdown (140°C), and automatic PFM/PWM mode transition. MODE pin selects forced PWM (noise-sensitive) or auto-switching (efficiency-optimized) operation; EN enables soft-start and shutdown with 0.2 μA typical ISD.
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 dropout |
| Output Voltage | 1.82 V ±2% - factory-trimmed fixed output; no external resistor divider required |
| Max Output Current | 600 mA - sufficient for RF transceivers and application processors in mobile handsets |
| Switching Frequency | 6 MHz (±10%) - enables use of sub-1-μH inductors and 0402 ceramic capacitors |
| Quiescent Current | 31 μA (typical, PFM mode) - extends standby time in always-on sensor nodes |
| Efficiency Peak | 90% at 6 MHz - achieved with synchronous rectification and low RDS(on) MOSFETs |
| Start-Up Time | 120 μs - internal soft-start limits inrush current during cold boot from battery |
Pinout & Package
TPS62620YFFT uses a 6-pin DSBGA (NanoFree™ WCSP) package with 1.30 mm × 0.96 mm body size and 0.5-mm pitch. The ultra-thin profile supports space-constrained mobile PCBs requiring sub-1-mm component height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.3–5.5 V; 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 to inductor and diode-free flyback path |
| FB | Feedback sense | Internal 1.82-V reference connected to output via direct trace; no external resistors needed |
| MODE | Operation mode control | Pull low for auto PFM/PWM; pull high for forced PWM only-critical for EMI-sensitive RF sections |
| EN | Enable input | Active-high logic; 1.0 V VIH threshold; drives internal soft-start and shutdown sequencing |
| GND | Ground reference | System ground return; must be low-impedance connection to minimize noise coupling into FB/SW |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains ≥85% efficiency from 10 μA to 600 mA load without external control logic |
| Integrated soft-start | 120-μs controlled ramp prevents input voltage sag during power-up from weak batteries |
| Ultra-small solution size | Total BOM requires only one 0.47-μH inductor and two 0402 MLCCs-solution area <12 mm² |
| Thermal and overload protection | Auto-shutdown at 140°C junction temp; cycle-by-cycle current limit protects against short-circuit faults |
| Low-noise forced-PWM option | Fixed 6-MHz operation when MODE = high-simplifies EMI filtering for GPS/WLAN coexistence |

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 (vs. TPS62620YFFT's 1.82 V); identical pinout, specs, and package | No functional difference in most 1.8-V rail applications; minor VOUT tolerance may affect margin-critical analog blocks | Select TPS62621YFFT if system requires nominal 1.8 V with same efficiency and footprint |
| TPS62067QDSGRQ1 | Automotive-grade AEC-Q100 qualified; 600 mA, 6 MHz, but 1.2–3.3 V adjustable output via external resistors | Requires external feedback network; larger 8-pin WSON package (2.0 × 2.0 mm); higher quiescent current (45 μA) | Choose TPS62067QDSGRQ1 only for automotive environments requiring qualification and adjustable VOUT |
Compared with TPS62621YFFT, the TPS62620YFFT offers tighter 1.82 V output for systems needing precise voltage alignment with legacy 1.8-V logic families; versus TPS62067QDSGRQ1, it provides smaller size, lower IQ, and fixed-output simplicity-but lacks AEC-Q100 certification and adjustability.

FAQ
What is the exact output voltage tolerance of the TPS62620YFFT?
The TPS62620YFFT has a total DC voltage accuracy of ±2% over temperature (–40°C to 85°C), line, and load conditions. This includes initial trim, drift, and regulation error-resulting in guaranteed output between 1.784 V and 1.856 V at 1.82 V nominal. This specification is confirmed in Section 7.5 of the SLVS848D datasheet and applies directly to the TPS62620YFFT variant.
Does the TPS62620YFFT require external compensation components?
No, the TPS62620YFFT uses an internally compensated frequency-locked ring-oscillating modulator architecture with no traditional feedback loop. It is fully stable with a 0.47-μH inductor and 4.7-μF output capacitor-no external compensation network is needed. This eliminates tuning effort and improves design reliability across process and temperature for the TPS62620YFFT.
Can the TPS62620YFFT operate from a 2.3-V input supply?
Yes, the TPS62620YFFT supports input voltages from 2.3 V to 5.5 V per its Recommended Operating Conditions. At 2.3 V input, it maintains regulation to 1.82 V output up to 600 mA load with >82% efficiency. The 2.05 V UVLO threshold ensures reliable startup even as Li-ion cells discharge to 2.3 V, making the TPS62620YFFT suitable for full-battery-range operation.
What is the thermal performance of the TPS62620YFFT in its YFFT package?
The TPS62620YFFT in the 6-pin DSBGA (YFFT) package has a junction-to-ambient thermal resistance (RθJA) of 130°C/W under standard JEDEC PCB conditions. With 600 mA load and 3.6 V input, typical power dissipation is ~120 mW-resulting in ~15.6°C junction rise above ambient. This enables reliable operation without heatsinking in handheld devices using the TPS62620YFFT.
How does the MODE pin affect efficiency and noise in the TPS62620YFFT?
When MODE = low, the TPS62620YFFT automatically switches between PWM (heavy load) and PFM (light load), achieving ≥85% efficiency from 10 μA to 600 mA. When MODE = high, it forces fixed 6-MHz PWM-reducing output noise and simplifying EMI filtering but lowering light-load efficiency to ~72%. This trade-off is documented in Section 8.3.1 and directly applies to the TPS62620YFFT.
