Product details
Overview
TPS62600YFFT from Texas Instruments is a 500-mA, 6-MHz synchronous step-down DC-DC converter in NanoFree™ chip-scale packaging (CSP-6), delivering 1.83 V output with ±1.5% total DC voltage accuracy across 2.3 V–5.5 V input. It integrates P/N-channel MOSFETs, supports automatic PFM/PWM mode switching, and achieves 89% efficiency at full load-designed for Li-ion-powered portable devices requiring ultra-compact power solutions.
For engineers reviewing the TPS62600YFFT datasheet, TPS62600YFFT pinout, TPS62600YFFT application, or TPS62600YFFT equivalent, key selection criteria include its 35 ns minimum on-time, 30 µA quiescent current in PFM mode, 6-MHz regulated switching frequency, and compatibility with 0.47 µH air-core inductors and 4.7 µF ceramic output capacitors in sub-13 mm² layouts.
Technical Context
The TPS62600YFFT employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to deliver instantaneous transient response and inherent stability across varied inductor/capacitor values. Its dual current-limit protection (900–1100 mA P-MOS, 30 mA short-circuit) and thermal shutdown at 140°C ensure robust operation under fault conditions.
It operates in fixed-frequency PWM mode above ~100 mA load and transitions to pulse-skipping PFM below that threshold, maintaining high efficiency across 0–500 mA. The MODE pin enables forced PWM for noise-sensitive applications, while EN provides <1 µA shutdown current and internal soft-start limits inrush during startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.83 V with ±1.5% total DC accuracy-ensures stable core supply for low-voltage processors and RF ICs. |
| Max Output Current | 500 mA continuous-supports single-core application processors or multi-rail PMIC subsystems. |
| Switching Frequency | 6 MHz (±10%)-enables use of 0.47 µH chip inductors and reduces EMI filtering burden. |
| Quiescent Current | 30 µA typical in PFM mode-extends battery life in 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) with margin. |
| Min On-Time | 35 ns-supports high step-down ratios (e.g., 3.6 V → 1.83 V at ~50% duty cycle) without pulse skipping. |
| Shutdown Current | 0.2 µA typical-minimizes system leakage when powered off. |
Pinout & Package
TPS62600YFFT uses a 6-pin NanoFree™ chip-scale package (CSP-6, 1.2 mm × 1.2 mm, 0.5 mm pitch) with bottom-side solder bumps. Package thermal resistance is 125°C/W (θJA) on 4-layer JEDEC-standard board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to output node; internal 460 kΩ divider sets 1.83 V regulation point. |
| VIN (A2) | Power input | Supplies bias and switching circuitry; accepts 2.3–5.5 V with UVLO at 2.05 V. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFETs; requires external 0.47 µH inductor to output capacitor. |
| EN (B2) | Enable control | Pull high (>1 V) to activate; pull low to reduce current to <1 µA-no external pull-up required. |
| MODE (A1) | Operating mode select | Low = auto PFM/PWM; High = forced PWM-enables deterministic noise filtering in RF sections. |
| GND (C2) | Power ground | Return path for switch current and control logic; must be low-inductance connection to minimize noise. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small solution size | Total footprint <13 mm² using one 0402 inductor and two 0402 MLCCs-fits within tight mobile PCB real estate. |
| Sub-1-mm component profile | Max height 0.55 mm-meets Z-height constraints in slim smartphones and wearables. |
| Automatic PFM/PWM transition | Seamlessly shifts modes at ~100 mA load-maintains >85% efficiency from 1 mA to 500 mA. |
| Internal soft-start | <200 µs startup time with controlled inrush-prevents input rail collapse during cold boot. |
| Thermal & overload protection | 140°C shutdown with 10°C hysteresis plus dual MOSFET current limits-enables unattended operation in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62601YFFT | Fixed 1.8 V output (vs. 1.83 V); identical pinout, specs, and package-TI marks it "Not Recommended for New Designs". | Same mobile/portable use cases but requires validation of 30 mV lower output tolerance in system-level margining. | Select only if legacy design reuse or existing BOM alignment is required; TPS62600YFFT preferred for new designs. |
| TPS62260DRVR | 3-MHz switching, SOT-23-6 package, 1.8 V output, 600 mA rating-higher current but larger footprint and lower frequency. | Better suited for space-tolerant industrial sensors than ultra-compact mobile; lacks NanoFree profile. | Choose when higher output current or SOT-23 assembly compatibility outweighs size/efficiency trade-offs. |

FAQ
What is the exact output voltage of the TPS62600YFFT and how tightly is it regulated?
The TPS62600YFFT delivers a fixed 1.83 V output with ±1.5% total DC voltage accuracy over temperature, line, and load conditions. This specification includes initial tolerance, line regulation (0.25%/V), load regulation (-0.0003%/mA), and thermal drift-ensuring reliable operation for 1.8 V nominal core supplies in portable processors. The FB pin connects to the output via an internal 460 kΩ resistor divider calibrated to this precise value.
Does the TPS62600YFFT require external compensation components?
No, the TPS62600YFFT features fully internal compensation optimized for standard 0.47 µH inductors and 4.7 µF ceramic output capacitors. Its frequency-locked ring-oscillating modulator architecture eliminates the need for external compensation networks, reducing BOM count and layout complexity while ensuring stability across L and C variations-verified per TI's SLVS678 datasheet.
How does the MODE pin affect efficiency and noise performance in the TPS62600YFFT?
When the MODE pin is pulled low, the TPS62600YFFT automatically switches between PWM (moderate/heavy load) and PFM (light load) to maximize efficiency-achieving 30 µA quiescent current and >85% efficiency down to 1 mA. Pulling MODE high forces fixed-frequency PWM operation, eliminating PFM frequency variation for easier EMI filtering but reducing light-load efficiency by ~15–20 percentage points.
What protection features are integrated into the TPS62600YFFT?
The TPS62600YFFT integrates current limiting on both P-channel (900–1100 mA) and N-channel (30 mA short-circuit) MOSFETs, thermal shutdown at 140°C with 10°C hysteresis, undervoltage lockout at 2.05 V, and internal soft-start. These features collectively prevent damage during startup, overload, overtemperature, or input brownout-enabling robust standalone operation without external supervision circuitry.
Can the TPS62600YFFT operate from a single-cell Li-ion battery throughout its full discharge range?
Yes-the TPS62600YFFT supports 2.3 V to 5.5 V input, covering the entire usable discharge curve of a single Li-ion cell (4.2 V down to ~2.7 V) with margin. Its 2.05 V UVLO threshold ensures clean startup above 2.1 V, and the 6-MHz switching frequency maintains regulation even at low duty cycles near end-of-discharge, making it ideal for battery-powered portable systems.
