Product details
Overview
TPS62601YFFT from Texas Instruments is a 6-MHz synchronous step-down DC-DC converter in NanoFree™ CSP-6 packaging, delivering 1.8 V at up to 500 mA output current with ±1.5% total DC voltage accuracy. It operates across 2.3 V–5.5 V input range, features automatic PFM/PWM mode switching, and targets ultra-compact battery-powered systems such as smartphones and Bluetooth modules.
For engineers reviewing the TPS62601YFFT datasheet, TPS62601YFFT pinout, TPS62601YFFT application, or TPS62601YFFT equivalent, key selection considerations include its 35 ns minimum on-time, 30 µA quiescent current in PFM mode, 6-MHz regulated switching frequency, integrated soft-start (<200 µs), and thermal/overcurrent protection - all within a sub-1-mm profile requiring only three external components.
Technical Context
The TPS62601YFFT employs a frequency-locked ring-oscillating modulator architecture with no traditional compensated feedback loop, enabling instantaneous transient response and inherent stability across L and CO variations. It integrates dual MOSFET current limits (P-MOS: 900–1100 mA; N-MOS: 30 mA short-circuit limit) and dynamic voltage positioning during power-save mode.
Its MODE pin selects between automatic PFM/PWM operation (MODE = LOW) for peak efficiency or forced PWM (MODE = HIGH) for noise-sensitive applications. The EN pin enables shutdown with <1 µA current draw, while 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 with ±1.5% total DC accuracy over line/load/temperature - ensures stable core supply for low-voltage processors. |
| Max Output Current | 500 mA continuous - supports RF transceivers and baseband ICs in portable handsets without external current boosting. |
| Switching Frequency | 6 MHz (regulated, ±10% over conditions) - enables use of 0.47 µH air-core inductor and ultra-small ceramic capacitors (CI = 2.2 µF, CO = 4.7 µF). |
| Quiescent Current | 30 µA (typ) in PFM mode - extends battery runtime in standby/sleep states of mobile devices. |
| Min On-Time | 35 ns - supports high step-down ratios (e.g., 3.6 V → 1.8 V at ~50% duty cycle) while maintaining regulation at 6 MHz. |
| Efficiency | 89% at 6 MHz, 3.6 VIN, 1.8 VOUT, 200 mA - minimizes thermal dissipation in sealed handheld enclosures. |
| Shutdown Current | 0.2 µA (typ) - meets stringent system-level leakage budgets during deep-sleep modes. |
Pinout & Package
NanoFree™ Chip-Scale Package (CSP-6), 0.8 mm × 0.8 mm × 0.27 mm, 0.4 mm pitch, bottom-side solder balls. RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to output node; internal 460 kΩ divider sets 1.8 V via VREF = 0.8 V - no external resistors required. |
| VIN (A2) | Input power supply | Accepts 2.3–5.5 V; powers internal bias circuitry and gate drivers - compatible with single-cell Li-ion (2.7–4.2 V) and extended-range batteries. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair; requires low-ESR ceramic capacitor (4.7 µF) and 0.47 µH inductor - critical for EMI control. |
| EN (B2) | Enable control | Active-high logic; must be terminated (not floating); pulls device into <1 µA shutdown when grounded - enables system-level power sequencing. |
| MODE (A1) | Operation mode select | LOW = auto PFM/PWM; HIGH = forced PWM - allows dynamic noise/efficiency trade-off without firmware change. |
| GND (C2) | Power ground | Primary return path for switch current and IC bias; requires low-inductance PCB connection to minimize voltage spikes and EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains >85% efficiency from 1 mA to 500 mA load - eliminates manual mode control and optimizes battery life across usage states. |
| Internal soft-start | <200 µs startup time with controlled inrush - prevents input voltage sag on weak sources like coin-cell or aging Li-ion batteries. |
| Thermal and overload protection | 140°C thermal shutdown with 10°C hysteresis + dual MOSFET current limiting - enables robust operation in unventilated handheld enclosures. |
| Total solution size | <13 mm² including 0.47 µH inductor and two 0402 MLCCs - fits within tight board real estate constraints of modern smartphones. |
| NanoFree™ CSP-6 packaging | 0.8 mm × 0.8 mm footprint, 0.27 mm height - supports ultra-thin form factors and reduces parasitic inductance vs. QFN alternatives. |

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 |
|---|---|---|---|
| TPS62600YFFT | Fixed 1.83 V output (vs. TPS62601YFFT's 1.8 V); identical package, pinout, and electrical specs otherwise. | Suitable where tighter 1.83 V tolerance aligns with specific SoC VDD requirements (e.g., certain OMAP variants). | Select TPS62600YFFT only if 1.83 V matches target IC's nominal supply; otherwise TPS62601YFFT provides standard 1.8 V compliance. |
| TPS62260DRVR | Same 6-MHz operation but in 6-pin WSON (2 mm × 2 mm); higher 600 mA IOUT; 25 µA IQ; no MODE pin - fixed PWM only. | Better suited for space-tolerant designs needing higher current or simpler control; lacks PFM flexibility. | Choose TPS62260DRVR when board area permits larger package and 600 mA headroom is required; retain TPS62601YFFT for ultra-compact, efficiency-critical layouts. |
Compared with TPS62600YFFT, the TPS62601YFFT offers a standardized 1.8 V output aligned with common digital I/O rails, while TPS62260DRVR trades package size and PFM capability for higher current and slightly lower quiescent current - making TPS62601YFFT optimal for miniaturized, battery-sensitive applications demanding precise 1.8 V regulation.

FAQ
What is the output voltage tolerance of the TPS62601YFFT?
The TPS62601YFFT delivers a fixed 1.8 V output with ±1.5% total DC voltage accuracy across line, load, and temperature (–40°C to +85°C). 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 I/O domains in portable SoCs.
Does the TPS62601YFFT require external feedback resistors?
No, the TPS62601YFFT does not require external feedback resistors. It uses an internal resistor divider referenced to a 0.8 V bandgap, configured for a fixed 1.8 V output. The FB pin connects directly to the output node, eliminating component count and layout sensitivity associated with external resistor networks.
How does the MODE pin affect efficiency and noise performance in the TPS62601YFFT?
When MODE = LOW, the TPS62601YFFT automatically switches between PFM (light load) and PWM (heavy load), achieving up to 89% efficiency at 200 mA while minimizing quiescent current to 30 µA. When MODE = HIGH, it forces fixed-frequency PWM operation - reducing output voltage ripple and simplifying EMI filtering at the cost of ~5–10% lower light-load efficiency.
What is the minimum recommended inductor value for stable operation of the TPS62601YFFT?
The TPS62601YFFT is optimized for a 0.47 µH air-core inductor, but supports 0.3 µH to 1.3 µH. Using ≤0.47 µH maintains 6-MHz regulation and fast transient response; values <0.3 µH risk frequency droop under high duty cycles. Inductor saturation current must exceed 900 mA to accommodate P-MOS current limit.
Can the TPS62601YFFT operate from a 2.3 V input supply?
Yes, the TPS62601YFFT operates down to 2.3 V input, with undervoltage lockout (UVLO) releasing at 2.05 V (typ). At 2.3 V, it delivers full 500 mA output at 1.8 V with >82% efficiency (per typical curves), making it suitable for deeply discharged Li-ion cells and wide-input portable systems.
