Product details
Overview
TPS62622YFFT from Texas Instruments is a 600-mA, 6-MHz synchronous step-down DC/DC converter in NanoFree™ WCSP packaging, optimized for Li-ion–powered portable devices. It delivers 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 TPS62622YFFT datasheet, TPS62622YFFT pinout, TPS62622YFFT application, or TPS62622YFFT equivalent, key selection criteria include its regulated 6-MHz PWM/PFM auto-switching operation, 2.3–5.5 V input range, 1.5 V fixed output, ultra-low quiescent current, and chip-scale 1.30 mm × 0.96 mm DSBGA package with integrated soft-start and thermal shutdown.
Technical Context
The TPS62622YFFT employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous load/line transient response and inherent stability across L-COUT variations. Its non-linear control enables seamless PFM-to-PWM mode transition without external components.
It integrates dual MOSFETs (P-channel RDS(on) = 480 mΩ, N-channel RDS(on) = 140 mΩ at 3.6 V), undervoltage lockout (2.05 V threshold), and thermal shutdown (140°C trip). The MODE pin selects between automatic PFM/PWM switching or forced PWM for noise-sensitive applications.
Key Specifications

|---|---|
| Output Voltage | Fixed 1.5 V with ±2% total DC accuracy over temperature and line/load |
| Max Output Current | 600 mA continuous-supports core logic rails in mobile SoCs and RF ICs |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz) with FLL-enables <1 mm height inductor use |
| Quiescent Current | 31 μA in PFM mode-extends standby time in always-on sensor nodes |

Pinout & Package
TPS62622YFFT uses a 6-pin DSBGA (NanoFree™ WCSP) package measuring 1.30 mm × 0.96 mm with 0.5-mm pitch. The die-side ball layout matches TI's standard YFF/YFD footprint and supports solder reflow per JEDEC J-STD-020.
| 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 |
| FB | Feedback sense | Internal 1.5 V reference divider-no external resistors needed for fixed-output variant |
| MODE | Operating mode select | Pull low for auto PFM/PWM; pull high for forced PWM-critical for EMI-sensitive RF sections |
| EN | Enable control | Active-high logic; 1.0 V VIH threshold; drives device into 0.2 μA shutdown when grounded |
| GND | Ground reference | System ground return; must be connected directly to thermal pad under die for thermal performance |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the exact output voltage tolerance of the TPS62622YFFT over temperature and load?
The TPS62622YFFT provides a fixed 1.5 V output with ±2% total DC voltage accuracy across –40°C to 85°C ambient temperature, 2.3–5.5 V input, and 0–600 mA load. This specification includes initial tolerance, line regulation, load regulation, and temperature drift-verified per TI's SLVS848D datasheet Section 7.5.
Does the TPS62622YFFT require external feedback resistors to set its output voltage?
No, the TPS62622YFFT does not require external feedback resistors. It is a fixed-output variant with an internally trimmed 1.5 V reference and integrated resistor divider. The FB pin is connected directly to the output capacitor-no external components are needed for regulation.
Can the TPS62622YFFT operate from a single-cell Li-ion battery throughout its full discharge curve?
Yes, the TPS62622YFFT operates from 2.3 V to 5.5 V input, covering the full usable range of a single-cell Li-ion battery (2.7 V to 4.2 V nominal, down to 2.3 V cutoff). Its 2.05 V UVLO threshold ensures reliable startup even at end-of-discharge voltages.
How does the MODE pin affect efficiency and noise performance in the TPS62622YFFT?
When the MODE pin is pulled low, the TPS62622YFFT automatically switches between PFM (light load, 31 μA IQ) and PWM (heavy load, 90% efficiency). When pulled high, it forces fixed-frequency PWM-reducing EMI but lowering light-load efficiency by ~15–20 percentage points due to constant switching losses.
What thermal derating applies to the TPS62622YFFT in a typical 2-layer PCB layout?
In a standard 2-layer board with 1-in² copper pour under the DSBGA package, the TPS62622YFFT's junction-to-ambient thermal resistance is 130°C/W. At 600 mA output and 3.6 V input, power dissipation is ~180 mW-resulting in ~23°C junction rise above ambient. No derating is required below 60°C ambient per TI's thermal guidelines.
