Product details
Overview
TPS62560DRVT from Texas Instruments is a synchronous step-down DC-DC converter optimized for battery-powered portable applications. It delivers up to 600 mA output current from 2.5 V–5.5 V input (e.g., single Li-ion or AA/AAA cells), features 2.25-MHz fixed-frequency PWM operation, supports power-save mode with dynamic voltage positioning, and uses an adjustable feedback architecture with 0.6-V internal reference. It targets point-of-load regulation in handheld devices.
For engineers reviewing the TPS62560DRVT datasheet, TPS62560DRVT pinout, TPS62560DRVT application, or TPS62560DRVT equivalent, key selection criteria include its 6-pin SON package (2 mm × 2 mm), MODE pin-controlled PFM/PWM transition, 15-μA quiescent current in light-load PFM mode, and 100% duty-cycle low-dropout capability for extended battery runtime.
Technical Context
The TPS62560DRVT employs voltage-mode control with input-voltage feed-forward for fast line/load regulation and stable operation with small ceramic capacitors. Its dual-mode operation-automatically transitioning between 2.25-MHz PWM at medium/heavy loads and discontinuous-conduction PFM at light loads-is governed by the MODE pin state and load current threshold.
Dynamic voltage positioning raises the regulated output by +1% in PFM mode to minimize transient undershoot during load steps. The integrated high-side (252 mΩ typ) and low-side (194 mΩ typ) MOSFETs enable synchronous rectification, while undervoltage lockout (1.85 V falling threshold) and thermal shutdown (140°C) provide system-level protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V), alkaline (up to 5.5 V), and USB-powered systems without external LDO pre-regulation. |
| Output Current | Up to 600 mA - sufficient for powering low-power DSP cores, RF transceivers, or microcontroller subsystems in portable electronics. |
| Switching Frequency | 2.25 MHz fixed - enables use of compact 2.2-μH inductors and 10-μF ceramic output capacitors, minimizing solution footprint and height. |
| Quiescent Current | 15 μA (PFM mode, no switching) - extends battery life in standby or sleep states of always-on sensors or wearables. |
| Feedback Reference | 0.6 V - sets precise output voltage via external resistor divider; enables adjustable outputs from 0.85 V to VIN, including common rails like 1.2 V, 1.8 V, or 3.3 V. |
| Efficiency Peak | ≥90% at 3.6 VIN/1.8 VOUT/100 mA - achieved via synchronous rectification and optimized gate drive, reducing thermal load in sealed enclosures. |
| Shutdown Current | 0.5 μA - ensures negligible battery drain when disabled via EN pin, critical for long-term storage or emergency backup circuits. |
Pinout & Package
The TPS62560DRVT is housed in a thermally enhanced 6-pin SON (Small Outline No-lead) package measuring 2.00 mm × 2.00 mm × 0.8 mm, with an exposed thermal pad soldered to PCB ground for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Connection point for external inductor; carries high dv/dt switching waveform - requires tight layout and clearance from sensitive analog traces. |
| FB | Feedback Input | High-impedance node sensing output voltage via external resistor divider; must be routed away from SW and inductor to avoid noise coupling. |
| VIN | Input Power Supply | Primary power input; requires local 4.7-μF ceramic decoupling capacitor placed within 3 mm of the pin for EMI suppression and transient response. |
| GND | Power Ground | System return path for input/output currents; connected directly to exposed thermal pad for thermal and electrical integrity. |
| EN | Enable Control | Active-high logic input; pulling low disables regulator and reduces current draw to 0.5 μA - used for power sequencing or system wake/sleep control. |
| MODE | Operating Mode Select | Logic-controlled pin: GND enables automatic PFM/PWM transition; high forces fixed-frequency PWM - essential for noise-sensitive audio or RF sections. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to absorb load-step transients without external compensation, reducing required output capacitance by up to 30%. |
| 100% Duty-Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + RL) - sustains regulation down to ~1.9 V input for 1.8 V output, maximizing usable battery capacity. |
| Soft-Start Ramp | 250 μs output rise time (5% to 95%) limits inrush current and prevents input rail collapse during startup from weak sources like coin cells. |
| Integrated MOSFETs | 252 mΩ high-side and 194 mΩ low-side RDS(on) eliminate external FETs and gate drivers, reducing BOM count and layout complexity. |
| Thermal Shutdown Protection | 140°C trip with 20°C hysteresis prevents permanent damage during sustained overload or poor heatsinking - auto-recovery avoids manual reset. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62562DRVT | Fixed 1.8-V output; identical package, pinout, and MODE/EN functionality; no external feedback resistors required. | Eliminates resistor divider design effort but lacks output voltage flexibility; suited for systems with static 1.8-V rail requirements. | Select when board space is critical and 1.8 V is the only required output; verify compatibility with downstream 1.8-V ICs' absolute maximum ratings. |
| TPS62290DRVR | Higher 1-A output current; same 2.25-MHz frequency; improved light-load efficiency (12 μA IQ); requires different feedback network for adjustable outputs. | Supports higher-power peripherals (e.g., Wi-Fi modules); larger solution size due to 3.5-μH recommended inductor. | Choose for future-proofing or when peak load exceeds 600 mA; confirm thermal performance with 1-A continuous current in target enclosure. |
Compared with TPS62560DRVT, TPS62562DRVT simplifies design for fixed 1.8-V use cases but sacrifices adjustability, while TPS62290DRVR offers higher current headroom and lower quiescent current at the cost of increased inductor size and slightly different layout constraints.

FAQ
What is the recommended inductor value for TPS62560DRVT in standard operation?
The TPS62560DRVT is optimized for a 2.2-μH shielded power inductor with ≤110-mΩ DCR. This value balances ripple current (~300 mA peak-to-peak at 600 mA load), efficiency (>90%), and physical size. Inductors between 1.5 μH and 4.7 μH are supported, but deviating significantly affects loop stability and transient response - always validate with the TPS62560DRVT's specific compensation guidelines.
Can TPS62560DRVT operate with a 1.5-V input voltage?
No, TPS62560DRVT cannot operate with a 1.5-V input. Its absolute minimum input voltage is 2.5 V under recommended conditions, and undervoltage lockout triggers at 1.85 V (falling). Attempting operation below 2.5 V risks malfunction, unregulated output, or thermal shutdown. For sub-2-V battery chemistries, consider TI's TPS6274x series or discrete LDO solutions.
How does the MODE pin affect efficiency and noise performance of TPS62560DRVT?
When MODE = GND, TPS62560DRVT enters power-save mode, automatically switching between PWM and PFM to maintain >85% efficiency down to 1 mA load - ideal for battery life. When MODE = VIN, it forces fixed 2.25-MHz PWM, increasing light-load quiescent current to 3.8 mA but eliminating PFM frequency variation - critical for meeting EMI limits in RF-sensitive designs like Bluetooth headsets.
What is the purpose of the 22-pF capacitor (C1) shown in the TPS62560DRVT typical application schematic?
The 22-pF capacitor (C1) is an external feed-forward capacitor connected from FB to SW. It improves load-transient response by injecting a derivative term into the error amplifier, counteracting output voltage droop during rapid current steps. Omitting C1 degrades transient recovery time by up to 2×; values between 22 pF and 33 pF are validated for stability with the 2.2-μH/10-μF default filter.
Is TPS62560DRVT RoHS-compliant and lead-free?
Yes, TPS62560DRVT is RoHS-compliant and lead-free. It meets JEDEC J-STD-020 moisture sensitivity level 2a (MSL-2a) and is qualified for reflow soldering per IPC/JEDEC J-STD-020. The device uses NiPdAu terminal finish and complies with EU RoHS Directive 2011/65/EU and China RoHS II - full compliance documentation is available in TI's official product folder for TPS62560DRVT.
