Product details
Overview
TPS62620YFFR from Texas Instruments is a 6-MHz synchronous step-down DC/DC converter in a 6-pin NanoFree™ WCSP package, delivering 1.82 V at up to 600 mA from 2.3 V–5.5 V input. It features automatic PFM/PWM mode switching, 31 μA quiescent current, ±2% DC output accuracy, and integrated soft-start for mobile power rail generation.
For engineers reviewing the TPS62620YFFR datasheet, TPS62620YFFR pinout, TPS62620YFFR application, or TPS62620YFFR equivalent, key selection criteria include light-load efficiency, sub-1-mm profile, fixed-frequency PWM forcing capability via MODE pin, and compatibility with 0402 ceramic capacitors and chip-scale inductors in space-constrained portable designs.
Technical Context
The TPS62620YFFR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation networks and enabling inherent stability across L-COUT variations. Its non-linear control loop delivers instantaneous transient response without external loop tuning.
It integrates dual MOSFETs (P-channel RDS(on) = 270 mΩ, N-channel RDS(on) = 140 mΩ at 3.6 V), undervoltage lockout (2.05 V threshold), thermal shutdown (140°C), and soft-start (120 μs typical). MODE pin selects between auto PFM/PWM or forced PWM operation; EN enables/disables with 0.2 μA shutdown current.
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 feedback resistors required. |
| Max Output Current | 600 mA - sufficient for RF transceivers, baseband processors, and sensor subsystems. |
| Switching Frequency | 6 MHz ±10% - enables use of <1 μH inductors and 0402 MLCCs; reduces solution size. |
| Quiescent Current | 31 μA - maintains >85% efficiency at 1 mA load, extending battery life in standby. |
| Efficiency Peak | 90% at 6 MHz - achieved at mid-load (e.g., 100–300 mA) with 3.6 V input and 1.82 V output. |
| Thermal Shutdown | 140°C with 10°C hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62620YFFR uses a 6-pin DSBGA (NanoFree™ WCSP) package measuring 1.30 mm × 0.96 mm with 0.5-mm pitch. The ultra-thin profile (≤0.45 mm height) supports stacked PCB architectures and thin mobile form factors.
| 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; connects to inductor; high dv/dt node requiring tight layout and ground guard ring. |
| FB | Feedback sense | Internally connected to 1.82 V reference; not externally accessible-no resistor divider needed. |
| MODE | Operating mode control | Pull low for auto PFM/PWM; pull high for forced PWM-enables noise-sensitive system-level filtering. |
| EN | Enable input | Active-high logic; drives device into 0.2 μA shutdown when grounded; must be terminated, not floating. |
| GND | Power ground | Return path for switch current and IC bias; requires low-inductance connection to thermal pad and PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM/PWM transition | Maintains >85% efficiency from 10 μA to 600 mA load without manual mode control. |
| Integrated soft-start | 120 μs ramp-up limits inrush current-prevents input voltage sag on weak battery sources. |
| Ultra-small solution size | Total footprint <12 mm² using 0402 capacitors and 0.47 μH chip inductor-ideal for camera modules and wearables. |
| Stable with ceramic output caps | No minimum ESR requirement; works with 1.6–10 μF X5R/X7R MLCCs-reduces BOM count and cost. |
| High-frequency operation | 6 MHz switching allows inductor values as low as 0.3 μH-minimizes magnetic volume and audible noise. |

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 (vs. TPS62620YFFR's 1.82 V); identical pinout, specs, and package. | Used where 1.8 V nominal is required by downstream logic; same PCB layout and bill-of-materials. | Select when system timing or voltage margining mandates exact 1.8 V-not 1.82 V. |
| TPS62067QDSGRQ1 | Automotive-grade AEC-Q100 qualified; 1.8 V output; 6-MHz operation; 25 μA IQ; but larger 8-pin WSON package (2.0 × 2.0 mm). | Suitable for automotive infotainment or ADAS sensors needing qualification; not drop-in due to footprint and thermal pad differences. | Choose only for automotive programs requiring AEC-Q100; otherwise TPS62620YFFR offers superior size and cost for consumer portables. |
Compared with TPS62621YFFR, the TPS62620YFFR provides tighter output regulation (±2% at 1.82 V vs. ±2% at 1.8 V) for margin-critical analog rails; compared with TPS62067QDSGRQ1, it delivers identical performance in half the footprint-critical for smartphones and wearables where board area directly impacts product thickness and cost.

FAQ
What is the exact output voltage tolerance of the TPS62620YFFR?
The TPS62620YFFR has a total DC output voltage accuracy of ±2% over temperature (–40°C to 85°C), line (2.3 V–5.5 V VIN), and load (0–600 mA). This includes initial trim, drift, and regulation error-verified per TI SLVS848D datasheet Section 7.5. The nominal output is 1.82 V, so the guaranteed range is 1.784 V to 1.856 V under all specified conditions. TPS62620YFFR does not require external feedback components.
Can the TPS62620YFFR operate from a single-cell Li-ion battery throughout its full discharge curve?
Yes. The TPS62620YFFR supports an input voltage range of 2.3 V to 5.5 V, covering the entire usable discharge range of a single-cell Li-ion battery (typically 4.2 V down to 2.5 V–2.7 V). Its undervoltage lockout activates at 2.05 V (typical), ensuring reliable shutdown before battery damage occurs. At 2.3 V input, TPS62620YFFR still delivers regulated 1.82 V at up to 600 mA, making it ideal for deep-discharge portable systems.
How does the MODE pin affect efficiency and noise performance in the TPS62620YFFR?
When MODE is pulled low, TPS62620YFFR operates in auto PFM/PWM mode-achieving >85% efficiency at loads below 10 mA while minimizing switching noise. When MODE is pulled high, it forces fixed 6-MHz PWM operation, reducing output ripple and enabling predictable EMI filtering but lowering light-load efficiency to ~70%. This trade-off lets designers optimize TPS62620YFFR for either battery life (PFM) or spectral purity (PWM) per subsystem requirement.
What is the recommended inductor value for the TPS62620YFFR in a typical 1.82 V @ 300 mA application?
Texas Instruments recommends a 0.47 μH inductor (e.g., Murata LQM21PNR47MC0) for the TPS62620YFFR, as the internal compensation is optimized for this value with a 4.7 μF output capacitor. This yields optimal transient response, stability, and efficiency. Inductor values from 0.3 μH to 1.3 μH are supported-but 0.47 μH balances peak-to-peak ripple (~300 mA), size, and thermal performance. TPS62620YFFR's 6-MHz operation allows physically smaller inductors than lower-frequency buck converters.
Does the TPS62620YFFR include output capacitor discharge functionality?
No. Output capacitor discharge is implemented only in the TPS62624 variant (via a 15 Ω internal resistor). The TPS62620YFFR lacks this feature-its output discharges only through the load and parasitic paths after shutdown. If rapid output discharge is required (e.g., for safety or sequencing), an external bleed resistor or active discharge circuit must be added. This distinction is confirmed in the Device Comparison Table (Section 5) and Feature Description (Section 8.4.4) of the TPS62620YFFR datasheet.
