Product details
Overview
TLV62568PDRLR from Texas Instruments is a synchronous step-down buck DC-DC converter delivering up to 1 A output current, operating from 2.5 V to 5.5 V input, with adjustable output voltage (0.6 V to VIN), 1.5-MHz fixed-frequency PWM operation, and integrated power good (PG) output. It serves as a compact, high-efficiency point-of-load regulator in space-constrained embedded systems.
For engineers reviewing the TLV62568PDRLR datasheet, TLV62568PDRLR pinout, TLV62568PDRLR application, or TLV62568PDRLR equivalent, key selection criteria include its SOT563-6 package footprint, 95% peak efficiency at 1.8 V/1 A, Power Save Mode for light-load operation, 35 µA quiescent current, and PG signal for rail sequencing in multi-rail power architectures.
Technical Context
The TLV62568PDRLR employs adaptive off-time peak-current control with fixed 1.5-MHz switching frequency under medium-to-heavy loads and automatically transitions to Power Save Mode at light loads to maintain high efficiency across the full 0–1 A range. Its internal high-side (150 mΩ) and low-side (100 mΩ) MOSFETs enable 100% duty-cycle low-dropout operation when needed.
It integrates critical protection features including overcurrent limiting (1.5 A typical), thermal shutdown (150 °C rising threshold), UVLO (2.45 V nominal with 100 mV hysteresis), and internal soft-start (900 µs). The PG pin provides open-drain power-good signaling referenced to FB voltage (95% rise / 90% fall thresholds), requiring an external pull-up ≤5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, USB, and industrial 3.3 V/5 V rails without external LDO pre-regulation. |
| Output Current | 1 A continuous - sufficient for powering ARM Cortex-M microcontrollers, FPGAs I/O banks, or sensor signal chains. |
| Switching Frequency | 1.5 MHz - enables use of small 2.2 µH inductors and ceramic capacitors, reducing solution size and EMI filtering burden. |
| Peak Efficiency | 95% at 1.8 V/1 A, 5 V input - minimizes thermal stress and extends battery runtime in portable applications. |
| Quiescent Current | 35 µA - ensures ultra-low standby power in always-on systems such as IoT edge nodes or security sensors. |
| Feedback Reference | 0.6 V ±2% - allows precise output setting down to 0.6 V using standard resistor dividers; enables 1.2 V, 1.8 V, 2.5 V, 3.3 V configurations. |
| Power Good Output | Open-drain PG with 95%/90% FB threshold - enables reliable power-rail sequencing and system reset assertion in multi-voltage designs. |
| Package | SOT563-6 (1.6 mm × 1.6 mm) - ultra-compact footprint ideal for dense PCB layouts in cameras, wearables, and network edge devices. |
Pinout & Package
SOT563-6 package: 1.60 mm × 1.60 mm body, 0.5-mm pitch, 6-pin ultra-small outline transistor with exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FB | Feedback input | Connects to resistor divider midpoint; regulates output by comparing against 0.6 V internal reference. |
| 2 - GND | Power ground | Main return path for input/output currents and IC bias; must be low-impedance connection to PCB ground plane. |
| 3 - VIN | Input supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic capacitor placed adjacent to pin for high-frequency decoupling. |
| 4 - SW | Switch node | Drives external 2.2 µH inductor; carries high di/dt square wave - must be short, wide, and shielded from sensitive traces. |
| 5 - EN | Enable input | Logic-high (>0.95 V) enables regulation; logic-low (<0.85 V) disables device, reducing VIN current to <2 µA. |
| 6 - PG | Power good output | Open-drain output asserting high-Z when VOUT ≥95% of target; sinks 1 mA when pulled low if VOUT drops below 90%. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically engages at light load to reduce switching frequency and quiescent current, maintaining >85% efficiency down to 10 mA. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (150 mΩ + inductor DCR), supporting 1.8 V output from 2.5 V input at full 1 A load. |
| Integrated Protection | Includes cycle-by-cycle overcurrent limit (1.5 A), thermal shutdown (150 °C), UVLO (2.45 V), and soft-start (900 µs) - no external components required. |
| Start-up into Pre-biased Output | Allows safe startup when output capacitor is pre-charged, preventing reverse current flow and system brownout during hot-plug events. |
| Low-Noise Feedback Path | FB pin designed for high PSRR and noise immunity; recommends routing away from SW node and using Kelvin connections for precision regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569PDRLR | Pin-to-pin compatible; higher 2.0 A current rating and improved light-load efficiency due to enhanced PSM algorithm. | Better suited for future-proofing or margin-critical 1.5 A peak loads; identical SOT563 footprint and PG functionality. | Select TLV62569PDRLR if design requires headroom beyond 1 A or tighter light-load regulation. |
| TPS62865DRLR | Higher 3.0 A rating, 4-MHz switching, smaller 1.0 mm × 1.0 mm WCSP package, but lacks PG output and requires external compensation. | Targets ultra-dense, high-performance applications where size and speed outweigh need for integrated PG or simplicity. | Choose TPS62865DRLR only when 3 A capability, 4 MHz operation, or sub-1.6 mm² footprint is mandatory - not a drop-in replacement. |
Compared with TLV62568PDRLR, TLV62569PDRLR offers higher current capacity and refined PSM while retaining full pin compatibility and PG functionality, whereas TPS62865DRLR trades PG integration and ease-of-use for higher performance and smaller size - requiring layout and loop compensation changes.

FAQ
What is the maximum output current supported by the TLV62568PDRLR?
The TLV62568PDRLR delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 125 °C, VIN = 2.5–5.5 V). Its internal current limit is 1.5 A typical, providing margin against transient overloads. Derating applies above 85 °C ambient; consult thermal data (RθJA = 149.8 °C/W) and layout guidelines for sustained 1 A operation.
Does the TLV62568PDRLR support power rail sequencing via its PG pin?
Yes, the TLV62568PDRLR includes a dedicated open-drain power good (PG) output that asserts high-impedance when VOUT reaches ≥95% of the regulated value and pulls low when VOUT falls below ~90%. This signal can drive the EN pin of downstream converters to implement controlled power-up/down sequencing in multi-rail systems.
Can the TLV62568PDRLR operate with a 2.5 V input to generate 1.8 V at 1 A?
Yes - the TLV62568PDRLR supports 100% duty-cycle operation, enabling it to regulate 1.8 V from a 2.5 V input at full 1 A load. Minimum input is determined by VOUT + IOUT × (RDS(on)_HS + inductor DCR); with RDS(on)_HS = 150 mΩ and typical DCR < 100 mΩ, 2.5 V is sufficient for stable 1.8 V/1 A output.
What package type does the TLV62568PDRLR use, and is it RoHS-compliant?
The TLV62568PDRLR uses the SOT563-6 package: a 1.6 mm × 1.6 mm, 0.5-mm pitch surface-mount outline with six terminals and an exposed thermal pad. It is RoHS-compliant, lead-free, and halogen-free per TI's environmental standards, qualified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL 1).
How does Power Save Mode affect regulation accuracy and output ripple in the TLV62568PDRLR?
In Power Save Mode (engaged below ~100 mA), the TLV62568PDRLR reduces switching frequency and skips pulses to minimize quiescent current. This causes slight output voltage rise (~1–2%) above nominal and increases low-frequency output ripple. Adding a larger output capacitor (e.g., 22 µF instead of 10 µF) mitigates both effects while preserving light-load efficiency.
Is the TLV62568PDRLR compatible with WEBENCH® Power Designer?
Yes - the TLV62568PDRLR is fully supported in TI's WEBENCH® Power Designer tool. Engineers can enter input/output requirements (e.g., VIN = 5 V, VOUT = 1.8 V, IOUT = 1 A) to auto-generate optimized schematics, perform efficiency/thermal simulations, select real-time available components, and export CAD-ready layouts - all validated for TLV62568PDRLR electrical and thermal behavior.
