Product details
Overview
TLV62568APDRLR from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 2 A output current with forced PWM operation, 1.5-MHz switching frequency, and 95% peak efficiency at 5-V input. It features integrated 100-mΩ high-side and 60-mΩ low-side MOSFETs, power good (PG) open-drain output, and operates across 2.5 V to 5.5 V input for 1.8-V POL supplies in compact embedded systems.
For engineers reviewing the TLV62568APDRLR datasheet, TLV62568APDRLR pinout, TLV62568APDRLR application, or TLV62568APDRLR equivalent, key selection criteria include PG functionality, SOT563 thermal performance, 100% duty-cycle low-dropout capability, and compatibility with 1.0-µH inductors and 22-µF ceramic output capacitors in space-constrained designs.
Technical Context
The TLV62568APDRLR employs peak-current-mode control with adaptive off-time modulation to maintain stable 1.5-MHz switching across input (2.5–5.5 V), output (0.6–VIN), and load (0–2 A) variations. Its internal soft-start limits inrush current during enable, and it supports pre-biased output startup.
Thermal shutdown triggers at 150°C junction temperature with automatic recovery at 130°C; under-voltage lockout activates below 2.45 V with 100-mV hysteresis. The PG pin sinks up to 2 mA and asserts low when FB falls below 90% of nominal regulation voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A maximum continuous - supports SSD, IP camera, and router core rails without external current boosting. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB, and 3.3-V/5-V system rails. |
| Switching Frequency | 1.5 MHz typical - enables use of small 1.0-µH inductors and reduces EMI filtering burden. |
| Feedback Voltage | 0.6 V ±2% - sets precise output via resistor divider; enables 1.8-V output with R1=200 kΩ, R2=100 kΩ. |
| Efficiency | Up to 95% at 5-V input / 1.8-V/2-A output - minimizes thermal load in sealed enclosures. |
| Power Good Output | Open-drain PG with 2-mA sink capability - provides rail sequencing signal for multi-rail systems. |
| Thermal Shutdown | 150°C rising threshold with 20°C hysteresis - protects against sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.55-mm height) with exposed thermal pad for enhanced PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback input | Connects to resistor divider midpoint; regulates output by comparing to 0.6-V internal reference. |
| GND (Pin 2) | Power ground | Main return path for high-current SW and VIN paths; must be low-impedance connection to thermal pad. |
| VIN (Pin 3) | Input supply | Accepts 2.5–5.5 V; requires local 4.7-µF ceramic capacitor placed adjacent to minimize input ripple. |
| SW (Pin 4) | Switch node | Drives external 1.0-µH inductor; high di/dt node requiring short, wide trace routing and minimal loop area. |
| EN (Pin 5) | Enable input | Active-high logic; 1.2-V min VIH ensures reliable turn-on from 1.8-V GPIO; must not float. |
| PG (Pin 6) | Power good output | Open-drain status signal; requires external pull-up ≤5.5 V; used for rail sequencing or fault monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM operation | Eliminates frequency variation and subharmonic oscillation - ensures consistent EMI profile across load range. |
| 100% duty cycle mode | Enables dropout as low as IOUT × (100 mΩ + inductor DCR) - sustains regulation near input rail collapse. |
| Low RDS(on) switches | 100 mΩ (HS) / 60 mΩ (LS) - reduces conduction loss and improves full-load efficiency over competitive 2-A buck converters. |
| Internal soft-start | 0.9-ms ramp time - prevents inrush into large output caps and avoids brownout on weak input sources. |
| Overcurrent protection | Peak switch current limit of 2 A - protects internal FETs and input source during short-circuit or overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569APDRLR | 2-A rated output current (vs. 2-A for TLV62568APDRLR); identical PG, SOT563, and 1.5-MHz PWM architecture. | Supports higher peak loads in burst-mode applications like SSD write acceleration or Wi-Fi transmit bursts. | Select TLV62569APDRLR only if >2-A short-duration current is required; otherwise TLV62568APDRLR offers identical functionality at lower cost. |
| TPS6286518RTER | Higher 3-A rating, 2.5-MHz switching, and integrated compensation; no PG output; 1.2-mm height WSON package. | Better suited for ultra-thin portable devices needing smaller inductors but lacks rail sequencing capability. | Choose TPS6286518RTER for space-constrained designs where PG is unnecessary and 3-A headroom is critical. |
Compared with TLV62568APDRLR, TLV62569APDRLR delivers identical features with higher current headroom, while TPS6286518RTER trades PG functionality for higher frequency and current-making TLV62568APDRLR optimal for cost-sensitive, PG-dependent 2-A POL applications.

FAQ
What is the maximum output current supported by the TLV62568APDRLR?
The TLV62568APDRLR supports up to 2 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5–5.5 V). Its internal current limit is set to 2 A, and thermal performance in the SOT563 package allows sustained 2-A operation with adequate PCB copper area and airflow. Derating applies above 85°C ambient.
Does the TLV62568APDRLR include a power good (PG) output?
Yes, the TLV62568APDRLR includes an open-drain power good (PG) output on Pin 6. It asserts high-impedance when FB reaches ≥95% of nominal regulation voltage and pulls low (≤0.4 V at 2 mA) when FB drops below ~90%. A pull-up resistor to ≤5.5 V is required; unused PG pins may be left floating.
What is the switching frequency of the TLV62568APDRLR and is it adjustable?
The TLV62568APDRLR operates at a fixed typical switching frequency of 1.5 MHz. This frequency is internally generated and not user-adjustable. It remains stable across input voltage, output voltage, and load variations due to its adaptive off-time PWM control architecture.
Can the TLV62568APDRLR start up into a pre-biased output capacitor?
Yes, the TLV62568APDRLR supports pre-biased output startup. When enabled, it detects the existing output voltage and ramps the output to the target regulation level without forcing reverse current into the output capacitor, preventing potential damage or system instability during hot-swap or multi-rail sequencing events.
What package type and thermal characteristics does the TLV62568APDRLR use?
The TLV62568APDRLR uses the SOT563-6 package (1.60 mm × 1.60 mm, 0.55-mm height) with an exposed thermal pad. Its junction-to-ambient thermal resistance (RθJA) is 142.8°C/W on JEDEC-standard board layout, enabling 2-A operation with minimal copper area. Thermal shutdown activates at 150°C with 20°C hysteresis.
