Product details
Overview
TLV62569DRLR from Texas Instruments is a synchronous step-down buck DC-DC converter delivering up to 2 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 switching frequency, and 95% peak efficiency at 1.8 V/2 A. It serves as a compact, high-efficiency point-of-load regulator in space-constrained embedded power rails.
For engineers reviewing the TLV62569DRLR datasheet, TLV62569DRLR pinout, TLV62569DRLR application, or TLV62569DRLR equivalent, key selection criteria include its SOT563-6 package footprint, integrated 100 mΩ/60 mΩ MOSFETs, Power Save Mode for light-load efficiency, 35 µA quiescent current, and absence of Power Good (PG) functionality - distinguishing it from TLV62569PDRL.
Technical Context
The TLV62569DRLR employs adaptive off-time peak-current control 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 architecture integrates high-side (100 mΩ) and low-side (60 mΩ) MOSFETs, enabling 100% duty-cycle operation for ultra-low dropout under heavy load.
It operates in PWM mode at medium-to-heavy loads and automatically transitions to Power Save Mode (PSM) at light loads to sustain >85% efficiency down to 10 mA. Startup includes internal soft-start (900 µs), while protection features include overcurrent limiting (2.5 A typical), thermal shutdown (150°C), and UVLO (2.45 V threshold with 100 mV hysteresis).
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 3.3 V/5 V rails without external LDO pre-regulation. |
| Output Current | Up to 2 A continuous - sufficient for powering ARM Cortex-M cores, FPGAs I/O banks, or sensor signal chains. |
| Switching Frequency | 1.5 MHz typical - enables use of small 2.2 µH inductors and ceramic capacitors, reducing solution size. |
| Peak Efficiency | 95% at 1.8 V/2 A, 5 V input - minimizes thermal stress and extends battery runtime in portable designs. |
| Quiescent Current | 35 µA - ensures minimal standby power loss in always-on IoT nodes or wake-on-event systems. |
| FET RDS(on) | 100 mΩ (HS) / 60 mΩ (LS) - lowers conduction losses and improves full-load efficiency vs. discrete solutions. |
| Feedback Reference | 0.6 V ±2% - allows precise output setting via external resistor divider; supports 1.2 V, 1.8 V, 2.5 V, 3.3 V rails. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height) - ultra-compact footprint ideal for wearables, camera modules, and dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 5) | Enable logic input | Active-high digital control; must be pulled high (>0.95 V) to activate regulator; floating prohibited. |
| GND (Pin 2) | Power ground | Main return path for input/output currents; requires low-impedance connection to PCB ground plane. |
| SW (Pin 4) | Switch node | Connects to inductor and internal FETs; high dv/dt node requiring tight layout and minimal trace length. |
| VIN (Pin 3) | Input supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic capacitor placed adjacent to pin for EMI suppression. |
| FB (Pin 1) | Feedback input | Monitors output via resistor divider; high-impedance node sensitive to noise - route away from SW. |
| NC (Pin 6) | No-connect terminal | Internally unconnected; may be left floating, tied to GND, or connected to VOUT per layout optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically engages below ~100 mA load to reduce switching frequency and maintain >85% efficiency at light loads. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + DCRL) - critical for maintaining regulation near input rail (e.g., 2.8 V → 2.5 V). |
| Internal Soft-Start | 900 µs ramp time prevents inrush current into bulk capacitance - avoids brownout on weak sources like coin cells. |
| Overcurrent Protection | 2.5 A typical current limit (peak) - protects against short-circuit and overload without external sensing components. |
| Thermal Shutdown | 150°C trip temperature with 20°C hysteresis - safeguards silicon integrity during sustained overload or poor heatsinking. |
Applications
| Wireless Router PoL Supply | Network Video Camera Core Rail |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569PDRL | Includes open-drain Power Good (PG) output; identical SOT563-6 package and electrical specs otherwise. | Required where rail sequencing or system-level power monitoring is needed (e.g., FPGA configuration lock). | Select TLV62569PDRL only if PG signal integration justifies added cost and layout routing; TLV62569DRLR is optimal for cost- and space-sensitive non-sequenced rails. |
| TPS62865DRLR | Higher 4-A rating, 2.5-V to 5.5-V input, 1.8-MHz fSW, but larger 1.2-mm height and different pinout (no NC pin). | Better suited for future-proofing or higher-current upgrades (e.g., next-gen SoCs), but requires PCB redesign. | Choose TPS62865DRLR only when >2 A capability is confirmed necessary; TLV62569DRLR offers superior cost/performance for ≤2 A applications in same footprint class. |
Compared with TLV62569PDRL, TLV62569DRLR eliminates PG functionality to reduce cost and simplify enable-only control; versus TPS62865DRLR, it trades current headroom for lower profile and pin compatibility within legacy SOT563 designs.

FAQ
What is the maximum output current supported by the TLV62569DRLR?
The TLV62569DRLR delivers up to 2 A continuous output current under recommended operating conditions (TJ ≤ 125°C, proper PCB thermal design). Its overcurrent protection triggers at approximately 2.5 A peak, safeguarding the device during transient overload or short-circuit events. Derating applies above 85°C ambient; consult thermal metrics (RθJB = 27.0°C/W) for layout-specific limits.
Does the TLV62569DRLR include a Power Good (PG) output?
No, the TLV62569DRLR does not feature a Power Good output. Pin 6 is designated NC (No Connect), unlike the TLV62569PDRL which uses that pin for an open-drain PG signal. This omission reduces cost and simplifies designs where rail monitoring or sequencing is handled externally or not required.
What package type and dimensions does the TLV62569DRLR use?
The TLV62569DRLR is housed in a SOT563-6 package measuring 1.60 mm × 1.60 mm with 0.6 mm maximum height. This ultra-small outline transistor package enables high-density PCB layouts in portable and miniaturized electronics, and is compatible with standard SMT reflow processes.
How does the TLV62569DRLR manage efficiency at light loads?
The TLV62569DRLR automatically enters Power Save Mode (PSM) at light loads (< ~100 mA), reducing switching frequency and gate drive losses to maintain >85% efficiency down to 10 mA. This behavior is fully internal - no external configuration is needed - and ensures minimal quiescent power draw (35 µA) in standby states.
Can the TLV62569DRLR operate with 100% duty cycle, and what is its minimum dropout voltage?
Yes, the TLV62569DRLR supports 100% duty cycle operation to minimize dropout. The theoretical minimum input voltage is VOUT + IOUT × (RDS(on) + DCRL). With 2 A load, 100 mΩ HS FET, and a 20 mΩ inductor, dropout is ~240 mV - enabling regulation even when input sags to within ~0.25 V of the output voltage.
