Product details
Overview
TPS62060 from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter in an 8-pin WSON package, delivering up to 1.6 A output current with input voltage range 2.7 V to 6 V and adjustable output (0.8 V to VIN). It features automatic PFM/PWM mode transition, 97% peak efficiency at 3.3 VIN/1.8 VOUT, and integrated output discharge for battery-powered portable media players.
For engineers reviewing the TPS62060 datasheet, TPS62060 pinout, TPS62060 application, or TPS62060 equivalent, key selection considerations include its 2-mm × 2-mm footprint, 18-µA quiescent current in power-save mode, 100% duty-cycle low-dropout operation, and compatibility with 1-µH inductors and 10-µF ceramic capacitors for ultra-thin POL designs.
Technical Context
The TPS62060 employs voltage-mode control with input-voltage feed-forward for fast line/load regulation and uses a 3-MHz fixed-frequency PWM architecture that transitions automatically to PFM at light loads. Its internal 0.6-V reference enables precise output setting via external resistor divider, while clock dithering reduces EMI harmonics.
It integrates high-side and low-side MOSFETs with RDS(on) of 120 mΩ/90 mΩ (at 3.6 V), supports dynamic voltage positioning (+1% output offset in PFM), and includes undervoltage lockout (1.78 V fall / 1.95 V rise), thermal shutdown (150°C), and soft-start (500 µs to 95% VOUT).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 3 MHz ±0.4 MHz - Enables compact 1-µH inductor and 10-µF capacitor filtering; reduces solution size and improves transient response. |
| Input Voltage Range | 2.7 V to 6 V - Supports single-cell Li-ion (2.7–4.2 V) and 3.3 V/5 V system rails without external LDO pre-regulation. |
| Max Output Current | 1.6 A - Sustains full load across ambient temperature (–40°C to 85°C) with proper PCB thermal design (θJA = 64.7°C/W). |
| Output Voltage Accuracy | ±1.5% in PWM mode - Ensures stable core voltage for DSPs and microcontrollers under varying load and line conditions. |
| Quiescent Current | 18 µA typical in PFM mode - Extends battery runtime in always-on subsystems like audio codecs or sensor interfaces. |
| Shutdown Current | <1 µA - Minimizes leakage during system sleep states; internal SW-to-PGND discharge path clears output capacitance. |
| Efficiency Peak | 97% at 3.3 VIN/1.8 VOUT/1 A - Reduces thermal load in space-constrained handheld enclosures. |
| Package | 2 mm × 2 mm × 0.75 mm WSON-8 with PowerPAD - Requires exposed thermal pad soldering for junction-to-board θJB = 34.6°C/W performance. |
Pinout & Package
TPS62060 is housed in an 8-pin WSON (DSG) package with exposed PowerPAD for thermal dissipation. The package measures 2.00 mm × 2.00 mm × 0.75 mm nominal and requires land pattern per TI SLVSA95B layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pin 1) | Power ground return for output stage | Carries high di/dt switching current; must be connected directly to PowerPAD and low-inductance ground plane. |
| SW (Pin 2) | Switch node | Connects internal high/low-side MOSFETs to external inductor; critical for EMI and efficiency-keep trace short and wide. |
| AGND (Pin 3) | Analog ground reference | Reference for error amplifier and feedback circuitry; tie to PGND at single point near PowerPAD to avoid noise coupling. |
| FB (Pin 4) | Feedback input | Monitors output voltage via resistor divider; connects to 0.6-V internal reference-requires clean routing away from SW. |
| EN (Pin 5) | Enable control | Active-high logic input; drives device into <1-µA shutdown when pulled low; supports power sequencing with other rails. |
| MODE (Pin 6) | Operating mode select | Pull low for auto PFM/PWM; pull high for forced 3-MHz PWM-used to suppress switching noise in RF-sensitive sections. |
| AVIN (Pin 7) | Analog supply input | Bias supply for control circuitry; must be tied to PVIN and decoupled with 10-µF ceramic capacitor close to pin. |
| PVIN (Pin 8) | Power supply input | Main input for power stage; connect to 10-µF input capacitor and battery/system rail; shares AVIN connection. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to absorb load-step undershoot-eliminates need for oversized output capacitance. |
| 100% Duty-Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + RL)-extends usable battery range down to ~2.0 V for 1.8-V output. |
| Integrated Output Discharge | Internal 75–1450-Ω resistor between SW and PGND during shutdown-clears VOUT within milliseconds without external FET. |
| EMI-Optimized Clock Dithering | ±6 ns frequency modulation spreads spectral energy-reduces peak radiated emissions by >10 dB in 30–1000 MHz band. |
| Robust Protection Suite | Includes undervoltage lockout (1.78 V), thermal shutdown (150°C), foldback current limiting, and anti-shoot-through logic. |
| Ultra-Thin Solution Support | Validated with 1-mm height inductors (e.g., FDK MIPSAZ3225D) and 0603-size 10-µF X5R/X7R ceramics-meets <1.2-mm Z-height targets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62061DSGT | Fixed 1.8-V output; identical pinout, package, and electrical specs except FB pin internally tied to divider. | No external resistor network required; eliminates two passives but forfeits output adjustability. | Select when 1.8 V is fixed system requirement and BOM simplification outweighs flexibility needs. |
| TPS62130ARGTR | Higher 3-A rating, 2.5-V to 6-V input, 2.2-MHz switching, WQFN-16 package (3 mm × 3 mm); no internal discharge resistor. | Supports higher current loads and wider input range but requires larger PCB area and external discharge circuit. | Choose for systems scaling beyond 1.6 A or needing extended input range-accept trade-off of larger footprint and added components. |
Compared with TPS62061DSGT, the TPS62060 offers full output adjustability at no cost in size or efficiency; versus TPS62130ARGTR, it delivers identical performance in half the footprint and lower quiescent current, making it optimal for compact, battery-sensitive designs.

FAQ
What is the minimum input voltage required for TPS62060 to maintain 1.8-V output at 1.6-A load?
The minimum input voltage depends on output tolerance, load current, and MOSFET/inductor resistance. Using VINmin = VOmax + IOmax × (RDS(on)max + RL), with VOmax = 1.83 V (±1.5%), RDS(on)max = 180 mΩ, and RL = 30 mΩ, VINmin ≈ 2.14 V. The TPS62060 enters 100% duty cycle below this threshold to sustain regulation.
Can TPS62060 operate without an external feed-forward capacitor (Cff)?
No-TI SLVSA95B explicitly requires Cff (22 pF shown in typical schematic) for stable loop compensation. Omitting Cff degrades phase margin, increases output voltage overshoot during load transients, and may cause oscillation. The capacitor forms a zero with R1 to counteract LC filter pole effects.
Does TPS62060 support forced PWM mode across its entire load range?
Yes-pulling the MODE pin high forces continuous 3-MHz PWM operation regardless of load current. This eliminates PFM frequency variation and associated audible noise, but reduces light-load efficiency versus auto PFM/PWM mode where quiescent current drops to 18 µA.
How does the internal output discharge function work in TPS62060 during shutdown?
When EN is pulled low, the TPS62060 disables all internal circuits and activates an internal 75–1450-Ω resistor between SW and PGND. This discharges the output capacitor through the inductor's parasitic path, clearing VOUT to near 0 V within milliseconds-no external discharge FET is needed.
Is TPS62060 compatible with 0603-size 10-µF ceramic output capacitors?
Yes-TI validates the TPS62060 with 0603 X5R/X7R 10-µF capacitors (e.g., TDK C1005X5R1C106M) in SLVSA95B. These provide sufficient effective capacitance at DC bias and enable the smallest possible solution size while meeting ripple and stability requirements.
