Product details
Overview
TPS62560DRVR from Texas Instruments is a synchronous step-down DC-DC converter optimized for battery-powered portable applications, delivering up to 600 mA output current from 2.5 V–5.5 V input (e.g., single Li-Ion or AA/AAA cells), featuring 2.25-MHz fixed switching frequency, adjustable output voltage (0.85 V to VIN), and Power Save Mode for high light-load efficiency.
For engineers reviewing the TPS62560DRVR datasheet, TPS62560DRVR pinout, TPS62560DRVR application, or TPS62560DRVR equivalent, key selection criteria include its 6-pin SON (2 mm × 2 mm) package, MODE pin-controlled PWM/PSM mode transition, 15-μA quiescent current in PFM, ±2.5% output accuracy in PWM mode, and integrated soft-start with 250-μs ramp-up time.
Technical Context
The TPS62560DRVR employs voltage-mode control with input-voltage feed-forward for fast line/load regulation and uses internal high- and low-side MOSFETs (RDS(on) = 252 mΩ / 194 mΩ typ.) to enable compact 2.2-μH inductor + 10-μF capacitor designs. Its 100% duty-cycle operation extends battery runtime by maintaining regulation down to VIN ≈ VOUT + IOUT×(RDS(on) + RL).
Power Save Mode dynamically transitions between PFM and PWM based on load, positioning output voltage +1% during light loads to minimize transient droop; MODE pin override forces fixed-frequency PWM for noise-sensitive systems. 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 (fully discharged to 2.5 V) and alkaline batteries without external LDO pre-regulation. |
| Max Output Current | 600 mA - sufficient for powering low-power DSPs, microcontrollers, or RF transceivers in handheld devices. |
| Switching Frequency | 2.25 MHz - enables use of small 2.2-μH inductors and 0603-size ceramic capacitors for ultra-compact PCB layouts. |
| Quiescent Current | 15 μA (PFM mode) - extends battery life in always-on, low-duty-cycle applications like sensor nodes or standby power rails. |
| Output Accuracy | ±2.5% in PWM mode - ensures stable core voltage for processors requiring tight supply tolerance. |
| Soft-Start Time | 250 μs (5% to 95% VOUT) - limits inrush current to prevent input rail collapse during cold boot from weak sources. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor heatsinking in sealed enclosures. |
Pinout & Package
TPS62560DRVR 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 power dissipation (RθJA = 67.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Connects to external inductor; carries high di/dt switching current - requires short, low-inductance routing to minimize EMI and voltage spikes. |
| FB | Feedback Input | Monitors output voltage via external resistor divider; open for fixed-output variants - sets VOUT = 0.6 V × (1 + R1/R2). |
| VIN | Input Supply | Accepts 2.5–5.5 V; must be decoupled with ≥4.7 μF ceramic capacitor placed near pin to suppress high-frequency ripple. |
| GND | Power Ground | Primary return path for power and control circuits; connects to exposed thermal pad for thermal and electrical integrity. |
| EN | Enable Control | Active-high logic input; pulling low disables converter and reduces supply current to <0.5 μA - used for power sequencing or system sleep control. |
| MODE | Operating Mode Select | Pull to GND for automatic PFM/PWM transition; pull to VIN for forced fixed-frequency PWM - critical for EMI-sensitive audio or RF sections. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to absorb sudden load steps without undershoot - eliminates need for oversized output capacitance. |
| 100% Duty-Cycle Operation | Extends usable battery range by regulating down to VIN ≈ VOUT, enabling full discharge of Li-ion cells from 4.2 V to 2.5 V without dropout. |
| Integrated Soft-Start | Controls output ramp rate to limit peak inrush current below 1 A - prevents brownout in multi-rail systems powered from shared battery sources. |
| Short-Circuit Protection | Current-limit comparators on both high- and low-side MOSFETs clamp peak switch current at 0.8–1.2 A - avoids thermal runaway during output faults. |
| Low-Noise PWM Mode | Fixed 2.25-MHz switching allows predictable EMI filtering with simple LC filters - meets Class B emissions requirements in portable medical devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62562DRVR | Fixed 1.8 V output (no FB divider required); identical package, pinout, and electrical specs otherwise. | Eliminates external resistors for 1.8 V rails but lacks adjustability - suitable only where output voltage is fixed and known pre-design. | Select when board space is constrained and 1.8 V is the sole required output; no layout change needed beyond removing R1/R2. |
| TPS62290DRVR | Higher 1-A output, 2.25-MHz operation, lower 12-μA quiescent current, same 2×2 SON package and pin compatibility. | Supports higher-current peripherals (e.g., Wi-Fi SoCs) while maintaining footprint - requires validation of thermal performance at 1 A. | Choose for future-proofing or when design may scale to >600 mA; verify junction temperature with RθJA = 67.8°C/W and 1-A load. |
Compared with TPS62560DRVR, TPS62562DRVR offers plug-and-play 1.8 V regulation with zero external components, while TPS62290DRVR provides headroom for higher current with identical layout - both retain the same MODE/EN control interface and thermal profile.

FAQ
What is the recommended inductor value for TPS62560DRVR in a typical application?
The TPS62560DRVR is optimized for a 2.2-μH inductor with ≤110-mΩ DCR, as validated in TI's reference design. Inductors between 1.5 μH and 4.7 μH are supported, but 2.2 μH delivers best balance of ripple current (≈300 mA pk-pk at 600 mA load), efficiency (>90% at 3.6 VIN/1.8 VOUT), and transient response. Using values outside this range may require re-tuning compensation components.
Can TPS62560DRVR operate with an input voltage below 2.5 V?
No - the absolute minimum input voltage for TPS62560DRVR is 2.5 V per datasheet specifications. Below this, undervoltage lockout activates at 1.85 V (falling threshold), disabling the output. Attempting operation below 2.5 V risks unstable regulation or shutdown; for sub-2.5 V inputs, consider TI's TPS6274x series or discrete LDO solutions.
How does the MODE pin affect efficiency and noise performance of TPS62560DRVR?
When MODE = GND, TPS62560DRVR enters Power Save Mode, automatically switching between PFM (high efficiency, ~15 μA IQ) and PWM (fixed 2.25 MHz) - ideal for variable loads. When MODE = VIN, it forces continuous PWM, increasing light-load IQ to ~3.8 mA but delivering predictable EMI spectrum for noise-critical analog sections. Efficiency drops ~5–10% at 10-mA load in forced PWM.
Is TPS62560DRVR pin-compatible with other devices in the TPS6256x family?
Yes - TPS62560DRVR and TPS62562DRVR share identical 6-pin SON (DRV) package, pinout, and footprint. TPS62561 (SOT-23-5) is not pin-compatible due to different package and missing MODE pin. Swapping TPS62560DRVR with TPS62562DRVR requires only removing the FB resistor divider; no PCB changes are needed.
What thermal considerations apply to TPS62560DRVR in a 600-mA continuous load application?
At 600 mA, 3.6 VIN/1.8 VOUT, TPS62560DRVR dissipates ~180 mW. With RθJA = 67.8°C/W and 25°C ambient, junction temperature rises ~12.2°C - well within the 125°C max rating. Ensure the exposed thermal pad is fully soldered to a ≥100-mm² copper pour connected to GND; insufficient pad area or poor soldering can double θJA and cause thermal shutdown.
