Product details
Overview
TPS62600YFFR from Texas Instruments is a 500-mA, 6-MHz synchronous step-down DC-DC converter in NanoFree™ CSP-6 packaging, delivering 1.83 V output with ±1.5% total DC 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-optimized for Li-ion-powered portable devices requiring ultra-small footprint and low quiescent current.
For engineers reviewing the TPS62600YFFR datasheet, TPS62600YFFR pinout, TPS62600YFFR application, or TPS62600YFFR equivalent, key selection criteria include its 35 ns minimum on-time, 30 µA quiescent current in PFM mode, 6-pin chip-scale package (CSP-6), and fixed 1.83 V output-critical for space-constrained, battery-sensitive designs in mobile and wireless applications.
Technical Context
The TPS62600YFFR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation loops-to deliver instantaneous transient response and inherent stability across varied inductor/capacitor combinations. Its dual current-limit protection (900–1100 mA P-MOS, 30 mA short-circuit) and thermal shutdown (140°C) ensure robust operation under fault conditions.
Operation is governed by MODE pin logic: grounded for automatic PFM/PWM transition (light-load efficiency), high for forced PWM (noise-sensitive fixed-frequency operation). Soft-start (<200 µs) and undervoltage lockout (2.05 V typ) further define its behavior during power-up and brownout scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.83 V with ±1.5% total DC accuracy-ensures stable core voltage for low-power processors without external feedback resistors. |
| Max Output Current | 500 mA continuous-supports single-core microcontrollers, RF transceivers, and memory subsystems in handheld devices. |
| Switching Frequency | 6 MHz regulated (5.4–6.6 MHz range)-enables use of sub-1 mm air-core inductors (e.g., 0.47 µH) and tiny MLCCs (4.7 µF). |
| Quiescent Current | 30 µA typical in PFM mode-extends battery life in standby/sleep states of portable electronics. |
| Input Voltage Range | 2.3 V to 5.5 V-fully covers discharged-to-full charge range of single-cell Li-ion batteries (2.7–4.2 V). |
| Min On-Time | 35 ns-supports high step-down ratios (e.g., 3.6 V → 1.83 V at ~50% duty) while maintaining regulation at 6 MHz. |
| Shutdown Current | <1 µA-minimizes leakage in system-level power gating architectures. |
| Package | NanoFree™ CSP-6 (1.2 mm × 0.8 mm, 0.5 mm pitch)-achieves total solution size <13 mm² with only three external components. |
Pinout & Package
TPS62600YFFR is housed in a 6-pin NanoFree™ chip-scale package (CSP-6), measuring 1.2 mm × 0.8 mm with 0.5 mm ball pitch. The package uses solder bumps directly on silicon die, enabling minimal PCB footprint and excellent thermal performance for high-density portable layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to output node; internal 460 kΩ resistor divider sets 1.83 V-no external resistors required. |
| VIN (A2) | Power supply input | Accepts 2.3–5.5 V; supplies bias and switching rails-must be decoupled with ≥2.2 µF ceramic capacitor near package. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFETs; connects to inductor-requires tight layout to minimize EMI and ringing. |
| MODE (A1) | Mode selection control | Ground = auto PFM/PWM; high = forced PWM-enables noise-sensitive operation without sacrificing light-load efficiency. |
| EN (B2) | Enable input | High = active; low = shutdown (<1 µA); must be terminated-controls system-level power sequencing and wake-up timing. |
| GND (C2) | Power ground | Primary return path for switch current and IC bias-requires low-impedance connection to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode switching | Maintains ≥89% efficiency from 1 mA to 500 mA load-eliminates need for external mode control logic in dynamic power systems. |
| 30 µA quiescent current (PFM) | Reduces no-load power loss in always-on subsystems (e.g., Bluetooth baseband, real-time clocks) without compromising startup speed. |
| Internal soft-start (<200 µs) | Limits inrush current during enable-prevents input voltage droop on weak sources like coin-cell batteries or shared PMIC rails. |
| Current overload & thermal shutdown | Protects against short-circuit (30 mA limit) and overtemperature (140°C trip, 10°C hysteresis)-enables reliable operation in unattended embedded systems. |
| Three-component total solution | Requires only one 0.47 µH inductor and two ceramic capacitors (2.2 µF input, 4.7 µF output)-reduces BOM count and assembly cost. |
| 6-MHz regulated oscillator | Enables consistent EMI profile and predictable filter design-avoids variable-frequency spread-spectrum complications in RF coexistence layouts. |

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 |
|---|---|---|---|
| TPS62601YFFR | Fixed 1.8 V output (vs. 1.83 V); otherwise identical electrical specs and pinout. | Suitable where 1.8 V nominal is required (e.g., certain ARM Cortex-M cores), but not drop-in for 1.83 V–tolerant loads. | Select TPS62601YFFR only when system voltage margin requires exact 1.8 V; verify load regulation compatibility before substitution. |
| TPS62260DRVR | Same 6-MHz architecture but in 6-pin SOT-23 package; 1.8 V output; higher 65 µA quiescent current. | Better thermal dissipation in high-ambient environments, but larger footprint (2.9 mm × 1.6 mm) and lower light-load efficiency. | Choose TPS62260DRVR if CSP handling is impractical or board-level thermal constraints exceed YFF-6 limits-accept 35 µA higher IQ. |
Compared with TPS62601YFFR, the TPS62600YFFR provides tighter 1.83 V output matching for precision analog subsystems; versus TPS62260DRVR, it delivers superior space efficiency and light-load performance at the cost of CSP assembly complexity.

FAQ
What is the output voltage tolerance of the TPS62600YFFR?
The TPS62600YFFR has 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 stable operation for precision analog and digital loads without external trimming.
Does the TPS62600YFFR require external feedback resistors?
No, the TPS62600YFFR does not require external feedback resistors. It features an internal resistor divider with 460 kΩ total resistance that sets the output to exactly 1.83 V. The FB pin is connected directly to the output node, simplifying layout and eliminating resistor tolerance errors and temperature drift effects.
How does the MODE pin affect efficiency and noise performance of the TPS62600YFFR?
When MODE is grounded, the TPS62600YFFR operates in automatic PFM/PWM mode-achieving up to 89% efficiency at light loads (e.g., 1 mA) via 30 µA quiescent current. When MODE is pulled high, it forces fixed-frequency PWM operation, reducing output ripple and EMI at the cost of lower light-load efficiency (≈70% at 1 mA), ideal for noise-sensitive RF sections.
What is the minimum recommended inductor value for stable operation of the TPS62600YFFR?
The TPS62600YFFR is optimized for 0.47 µH inductors (e.g., Murata LQM21PN1R0NGR), but supports 0.3 µH to 1.3 µH. Using ≤0.47 µH maintains 6 MHz switching under all conditions; values below 0.3 µH risk frequency collapse at high/low duty cycles. Inductor saturation current must exceed 900 mA to avoid current-limit triggering.
Is the TPS62600YFFR pin-compatible with other devices in the TPS6260x family?
Yes, the TPS62600YFFR is pin-compatible with TPS62601YFFR and all YFF-6 packaged variants in the TPS6260x family. They share identical CSP-6 pinout, thermal pad configuration, and terminal functions-allowing direct PCB reuse when changing output voltage (e.g., 1.8 V vs. 1.83 V) without layout modification.
