Product details
Overview
TPS62622YFFR 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 a fixed 1.5 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 TPS62622YFFR datasheet, TPS62622YFFR pinout, TPS62622YFFR application, or TPS62622YFFR equivalent, key selection criteria include its regulated 6-MHz switching frequency, automatic PFM/PWM mode transition, 2.3–5.5 V input range, 1.5 V fixed output, and chip-scale packaging for space-constrained designs.
Technical Context
The TPS62622YFFR uses a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous load and line transient response. Its non-linear control enables inherent stability across wide L/COUT variations without external compensation.
It integrates P-channel (480 mΩ typical RDS(on)) and N-channel (140 mΩ typical RDS(on)) MOSFETs, supports soft-start (120 µs), undervoltage lockout (2.05 V), thermal shutdown (140 °C), and offers MODE pin-selectable operation: auto PFM/PWM or forced PWM for noise-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V with ±2% total DC accuracy over temperature and line/load |
| Input Voltage Range | 2.3 V to 5.5 V-supports full Li-ion battery discharge curve (3.0–4.2 V nominal + extended range) |
| Max Output Current | 600 mA continuous-sufficient for RF transceivers and application processors' I/O rails |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz) - enables use of sub-1-µH inductors and 0402 ceramic capacitors |
| Quiescent Current | 31 µA typical in PFM mode-minimizes standby power loss in always-on subsystems |
| Efficiency | 90% peak at 6 MHz-maintains high conversion efficiency across 10 µA–600 mA load range |
| Thermal Shutdown | Activates at 140 °C junction temperature with 10 °C hysteresis-prevents thermal runaway in sealed enclosures |
Pinout & Package
TPS62622YFFR is housed in a 6-pin DSBGA (NanoFree™ WCSP) package measuring 1.30 mm × 0.96 mm with 0.5-mm pitch. The ultra-thin profile supports co-planar mounting beneath displays or batteries in slim mobile form factors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE (A1) | Mode selection input | Low = auto PFM/PWM; High = forced PWM-enables deterministic EMI filtering in noise-critical RF sections |
| VIN (A2) | Power input | Accepts 2.3–5.5 V; internal UVLO prevents startup below 2.05 V-ensures clean power sequencing |
| SW (B1) | Switch node | Connects to external inductor; integrates P/N MOSFETs-no external diode required, reduces BOM count |
| EN (B2) | Enable input | Active-high logic; pulls low to enter 0.2 µA shutdown-supports system-level power gating |
| FB (C1) | Feedback sense | Internally connected to 1.5 V reference; no external resistor divider needed-simplifies layout and saves board area |
| GND (C2) | Ground reference | Primary thermal and signal return path-requires solid copper pour under package for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains >85% efficiency from 10 µA to 600 mA load-eliminates manual mode control in dynamic power states |
| Integrated soft-start | 120 µs controlled ramp-up-limits inrush current into 4.7 µF output capacitor, preventing input voltage droop on weak sources |
| Low-ripple PFM mode | 24 mVPP output ripple at 1 mA-meets stringent noise requirements for RF front-end bias rails |
| Chip-scale packaging | 1.30 mm × 0.96 mm DSBGA-reduces solution footprint to <12 mm², including inductor and capacitors |
| Internal protection | Current limit (1.1 A), thermal shutdown (140 °C), and UVLO (2.05 V)-enables robust operation without external fault monitoring |

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; identical package, pinout, and electrical specs except VOUT | Used where higher I/O voltage is required (e.g., legacy memory interfaces) | Select when system requires 1.8 V instead of 1.5 V-no layout change needed |
| TPS62623YFFR | Fixed 1.225 V output; same thermal and transient performance; no output discharge function | Suitable for low-voltage core rails (e.g., 1.2 V FPGA I/O banks) | Choose for 1.225 V systems-identical footprint and control interface |

FAQ
What is the output voltage of the TPS62622YFFR?
The TPS62622YFFR provides a factory-trimmed fixed output voltage of 1.5 V with ±2% total DC accuracy across temperature, line, and load conditions. This eliminates the need for external feedback resistors and ensures consistent regulation for 1.5 V logic rails in portable devices without design iteration.
Does the TPS62622YFFR require external compensation components?
No, the TPS62622YFFR uses an internal frequency-locked ring-oscillating modulator architecture that does not rely on traditional voltage-mode or current-mode compensation. Its non-linear control loop is inherently stable with standard 0.47 µH inductors and 4.7 µF ceramic output capacitors-no external compensation network is needed.
How does the MODE pin affect TPS62622YFFR operation?
The MODE pin on the TPS62622YFFR selects between two operating modes: pulled low enables automatic PFM/PWM switching for maximum light-load efficiency, while pulled high forces fixed-frequency PWM operation for predictable EMI filtering in RF-sensitive circuits-both modes retain full 600 mA capability and 6 MHz regulation.
What protection features are integrated into the TPS62622YFFR?
The TPS62622YFFR integrates current limiting (1.1 A typical), thermal shutdown (140 °C with 10 °C hysteresis), undervoltage lockout (2.05 V threshold), and short-circuit protection. These functions operate autonomously without external circuitry, ensuring safe operation during input brownouts, output faults, or ambient temperature excursions.
Can the TPS62622YFFR be used with a 1.0 µH inductor?
Yes, the TPS62622YFFR is validated for use with 0.3–1.3 µH inductors. A 1.0 µH inductor (e.g., Murata LQM21PN1R0NGR) reduces peak-to-peak inductor ripple current and improves light-load efficiency, though it slightly slows transient response compared to the recommended 0.47 µH value-design trade-offs are documented in TI's SLVS848D datasheet.
