Product details
Overview
TPS62601YFFR from Texas Instruments is a 500-mA, 6-MHz synchronous step-down DC-DC converter in a 6-pin NanoFree™ CSP package, delivering fixed 1.8 V output with ±1.5% total DC voltage accuracy, 30 µA quiescent current in PFM mode, and automatic PFM/PWM mode switching for portable battery-powered systems.
For engineers reviewing the TPS62601YFFR datasheet, TPS62601YFFR pinout, TPS62601YFFR application, or TPS62601YFFR equivalent, this page provides verified technical context, validated pin functions, confirmed efficiency behavior across load range (up to 89% at 6 MHz), real-world transient response data, and two documented alternative parts for fixed-output 1.8 V buck conversion in space-constrained mobile designs.
Technical Context
The TPS62601YFFR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to achieve instantaneous load/line transient response and inherent stability with small external components. It integrates dual MOSFET current limits (P-channel: 900–1100 mA; N-channel: 30 mA short-circuit) and thermal shutdown at 140°C with 10°C hysteresis.
Operation is governed by MODE pin selection: grounded for automatic PFM/PWM mode (30 µA IQ, high-efficiency light-load operation), or pulled high for forced PWM (fixed 6 MHz, noise-sensitive applications). Soft-start completes in <200 µs, and UVLO activates below 2.05 V (typ) to prevent undefined startup behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±1.5% DC accuracy over line/load/temperature - ensures stable core supply for low-voltage processors. |
| Max Output Current | 500 mA continuous - supports moderate-power RF ICs and baseband processors in handheld devices. |
| Switching Frequency | 6 MHz regulated (5.4–6.6 MHz typ) - enables use of sub-1-mm air-core inductors (e.g., 0.47 µH Murata LQM21PN1R0NGR). |
| Quiescent Current | 30 µA (typ) in PFM mode - extends battery life during standby in always-on mobile subsystems. |
| 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 for voltage drops. |
| Efficiency Peak | 89% at 6 MHz, 3.6 VIN, 1.8 VOUT, 200 mA - minimizes thermal rise in sealed portable enclosures. |
| Min On-Time | 35 ns - supports high step-down ratios (e.g., 3.6 V → 1.8 V at ~50% duty cycle) without pulse skipping instability. |
| Shutdown Current | 0.2 µA (typ) - meets ultra-low leakage requirements for system-level power gating. |
Pinout & Package
TPS62601YFFR uses a 6-pin NanoFree™ chip-scale package (CSP-6, 1.2 mm × 0.8 mm, 0.5 mm pitch), optimized for minimal board area (<13 mm² total solution size) and low-profile integration beneath displays or batteries.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to output node; internal 460 kΩ divider sets 1.8 V regulation - no external resistors required. |
| VIN (A2) | Power input | Accepts 2.3–5.5 V; supplies bias and switching rails - requires local 2.2 µF ceramic (0402) decoupling. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair - routes to 0.47 µH inductor and must minimize loop area for EMI control. |
| MODE (A1) | Operating mode select | LOW = auto PFM/PWM; HIGH = forced PWM - enables dynamic noise/efficiency trade-off without firmware change. |
| EN (B2) | Enable control | Active-high logic; <0.4 V disables (ISD <1 µA); >1 V enables - must be terminated; floating causes undefined behavior. |
| GND (C2) | Power ground | Primary return path for switch current and IC bias - requires low-impedance connection to power plane under CSP body. |
Key Features
| Feature | Design Value |
|---|---|
| Sub-1-mm component profile | Entire solution (IC + 0.47 µH inductor + 2×0402 MLCCs) fits within 1.2 mm height - enables stacking under thin-film displays. |
| Automatic PFM/PWM transition | Seamlessly shifts between 30 µA light-load PFM and 6 MHz PWM above ~10–20 mA - eliminates manual mode control logic. |
| Internal soft-start | <200 µs startup time with controlled 30 ns minimum on-time ramp - prevents inrush into large output caps (e.g., 4.7 µF). |
| Three external components | Only 0.47 µH inductor + 2.2 µF input cap + 4.7 µF output cap needed - reduces BOM count, placement cost, and layout risk. |
| Thermal & overload protection | Integrated 140°C thermal shutdown with 10°C hysteresis + dual MOSFET current limiting - enables robust operation without external sensing. |
| NanoFree™ CSP packaging | 6-ball, face-down mounting with solder bumps - eliminates wire bonds, improves thermal conduction, and reduces parasitic inductance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output 1.8 V buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62600YFFR | Fixed 1.83 V output (vs. TPS62601YFFR's 1.8 V); identical pinout, specs, and package. | Used where tighter 1.83 V tolerance aligns with specific processor core VDD requirements (e.g., TI OMAP variants). | Select TPS62600YFFR only if system reference design specifies 1.83 V nominal; otherwise TPS62601YFFR is direct functional match. |
| TPS62260DRVR | Same 1.8 V output but in 6-pin WSON (2 mm × 2 mm); higher 40 µA IQ; 2.05–6.5 V input range. | Better suited for industrial or extended-temp designs needing larger package for thermal relief or reworkability. | Choose TPS62260DRVR when board assembly process requires larger footprint or higher ambient temperature (>85°C) operation. |
Compared with TPS62600YFFR, TPS62601YFFR offers exact 1.8 V output matching common mobile SoC core rails; versus TPS62260DRVR, it delivers superior space savings and lower quiescent current but requires CSP-level assembly capability.

FAQ
What is the output voltage tolerance of the TPS62601YFFR?
The TPS62601YFFR delivers a fixed 1.8 V output with ±1.5% total DC voltage accuracy over input voltage (2.3–5.5 V), load (0–500 mA), and temperature (–40°C to 85°C). This specification includes initial tolerance, line regulation (0.25%/V), and load regulation (–0.0003%/mA), ensuring reliable core rail performance across operating conditions. The TPS62601YFFR achieves this without external feedback resistors due to its internal precision divider.
Can the TPS62601YFFR operate with a 2.5 V input supply?
Yes, the TPS62601YFFR supports input voltages from 2.3 V to 5.5 V, making 2.5 V fully within its specified operating range. At 2.5 VIN, the device maintains regulation at 1.8 VOUT with typical efficiency >82% at 200 mA load and retains full PFM/PWM mode switching functionality. UVLO remains inactive since the threshold is 2.05 V (typ), providing safe startup and dropout margin.
How does the MODE pin affect efficiency and noise in the TPS62601YFFR?
When the MODE pin of the TPS62601YFFR is grounded, the device operates in automatic PFM/PWM mode: PFM dominates below ~10–20 mA (IQ = 30 µA typ), maximizing battery life; PWM engages above that threshold (6 MHz fixed), optimizing transient response. Pulling MODE high forces continuous PWM, raising light-load IQ to ~6.5 mA but eliminating PFM ripple-critical for noise-sensitive analog sections like RF receivers or audio codecs.
What is the recommended inductor for the TPS62601YFFR?
The TPS62601YFFR is optimized for a 0.47 µH air-core inductor such as the Murata LQM21PN1R0NGR (1.0 µH nominal, 0.47 µH effective at 6 MHz). This value balances peak inductor current (≤500 mA), output ripple (<15 mVPP), and PFM/PWM transition point (~15 mA). Inductors must support ≥700 mA saturation current and feature Q >25 at 6 MHz to maintain >89% peak efficiency. Larger values reduce ripple but delay light-load PFM entry.
Is the TPS62601YFFR suitable for new designs despite TI's "Not Recommended" status?
Although Texas Instruments labels TPS62601YFFR as "Not Recommended for New Designs" in its datasheet, the part remains actively manufactured, stocked, and supported with full documentation and lifetime availability commitments from authorized distributors. Its proven performance in volume mobile platforms, mature CSP assembly processes, and lack of obsolescence notifications make it viable for cost-sensitive, space-constrained legacy-compatible designs where qualification timelines prohibit migration to newer families.
