Product details
Overview
TLV62568DRLR from Texas Instruments is a synchronous step-down buck DC-DC converter delivering up to 1 A output current with 95% peak efficiency, 1.5-MHz fixed switching frequency, and 2.5-V to 5.5-V input range. It integrates 150-mΩ high-side and 100-mΩ low-side MOSFETs, supports adjustable output from 0.6 V to VIN, and features Power Save Mode for light-load operation in compact SOT563-6 packaging.
For engineers reviewing the TLV62568DRLR datasheet, TLV62568DRLR pinout, TLV62568DRLR application, or TLV62568DRLR equivalent, key selection considerations include its 1-A continuous output capability, 35-µA quiescent current, integrated power-good (PG) functionality in TLV62568P variants, thermal shutdown protection, and compatibility with ceramic output capacitors down to 10 µF.
Technical Context
The TLV62568DRLR employs adaptive off-time peak-current control to maintain stable 1.5-MHz switching across varying input voltage (2.5–5.5 V), output voltage (0.6–VIN), and load (0–1 A). Its internal architecture enables seamless transition between PWM mode at medium/heavy loads and Power Save Mode at light loads-reducing switching frequency and quiescent current to sustain >85% efficiency even below 10 mA.
It integrates full protection: overcurrent limiting (1.5-A peak switch current), thermal shutdown (150°C rising threshold), UVLO (2.45-V nominal turn-on with 100-mV hysteresis), and internal soft-start (900-µs ramp time). The device supports pre-biased start-up and 100% duty-cycle operation for ultra-low dropout, enabling regulation down to VIN ≈ VOUT + IOUT × (150 mΩ + inductor DCR).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1 A continuous - supports single-rail POL for SoC/FPGA core logic or sensor subsystems. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with Li-ion, USB, and 3.3-V/5-V system rails without external LDO. |
| Switching Frequency | 1.5 MHz - enables use of small 2.2-µH inductors and 10-µF ceramic output capacitors for space-constrained designs. |
| Quiescent Current | 35 µA - minimizes standby power loss in battery-powered applications like network cameras or IoT edge nodes. |
| Efficiency (Peak) | 95% at 1.8 V/1 A, 5-V input - reduces thermal load and extends battery runtime versus lower-efficiency alternatives. |
| Feedback Reference | 0.6 V ±2% - allows precise output setting via external resistor divider; enables 1.2-V, 1.8-V, 2.5-V, or 3.3-V outputs. |
| Protection Features | Overcurrent, thermal shutdown, UVLO, soft-start - eliminates need for external fault management circuitry. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.55-mm height), thermally enhanced with exposed pad (not electrically connected); suitable for high-density PCB layouts and automated assembly.
| 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 high-current SW node and internal control circuitry; must be low-impedance connection to PCB ground plane. |
| 3 (VIN) | Input power supply | Accepts 2.5–5.5 V; requires local 4.7-µF ceramic decoupling capacitor placed adjacent to pin. |
| 4 (SW) | Switch node | Drives external inductor; carries high di/dt pulses - must be routed short and wide to minimize EMI and voltage spikes. |
| 5 (EN) | Enable logic input | Active-high (0.95–1.2 V threshold); enables converter when pulled ≥1.2 V; <0.85 V disables and reduces IQ to <2 µA. |
| 6 (NC) | No-connect terminal | Not internally bonded; may be left floating or tied to VOUT for mechanical stability - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically engages below ~100 mA load to reduce switching frequency and maintain >85% efficiency at microamp-level loads. |
| 100% Duty-Cycle Operation | Enables dropout as low as IOUT × 150 mΩ - critical for maintaining regulation near input rail collapse (e.g., dying battery). |
| Integrated Power Good (PG) | Not present on TLV62568DRLR - PG is exclusive to TLV62568P variants (e.g., TLV62568PDRL); this part has NC at pin 6. |
| Robust Protection Suite | Includes cycle-by-cycle overcurrent limit (1.5-A peak), thermal shutdown (150°C), and UVLO with hysteresis - ensures safe operation under fault conditions. |
| Pre-biased Start-up Support | Allows clean startup into existing output voltage - prevents reverse current flow and avoids system reset during hot-swap or rail sequencing. |
Applications
| Network Video Camera | Set-Top Box |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569DRLR | Pin-to-pin compatible; higher 2-A output rating, same 1.5-MHz frequency and 2.5–5.5-V input range. | Supports higher-current rails (e.g., DDR memory, dual-core SoCs); requires larger inductor and output capacitance. | Select TLV62569DRLR only if >1-A continuous output is required; otherwise TLV62568DRLR offers better light-load efficiency and smaller solution size. |
| TPS62865DRLR | Higher 3-MHz switching frequency, 0.6-V reference, but 0.8-A max output and 2.7–6-V input range. | Better suited for ultra-thin devices needing sub-1-mm height; lacks 100% duty-cycle mode and has tighter input min. | Choose TPS62865DRLR for space-critical wearables; TLV62568DRLR remains preferred for industrial/automotive where robustness and dropout margin matter more. |
Compared with TLV62568DRLR, TLV62569DRLR provides headroom for future current scaling without layout change, while TPS62865DRLR trades output capability for higher frequency and smaller passives - making TLV62568DRLR the optimal balance of size, efficiency, and ruggedness for 1-A general-purpose POL.

FAQ
What is the maximum continuous output current of the TLV62568DRLR?
The TLV62568DRLR delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 5 V, VOUT = 1.8 V). Peak switch current is limited to 1.5 A for overcurrent protection. Derating applies at elevated ambient temperatures or with poor PCB thermal design - consult RθJA = 149.8°C/W and layout guidelines in the datasheet for thermal management.
Does the TLV62568DRLR include a power-good (PG) output?
No, the TLV62568DRLR does not include a power-good output. That feature is exclusive to TLV62568P variants such as TLV62568PDRL (which uses pin 6 as PG). TLV62568DRLR has a no-connect (NC) terminal at pin 6 - it must be left floating or tied to VOUT for mechanical stability, with no functional impact.
What is the recommended output capacitor value for stable operation of the TLV62568DRLR?
The TLV62568DRLR is optimized for 10 µF to 47 µF ceramic output capacitors (X5R/X7R dielectric, 0805 or larger). A 10-µF, 10-V, X7R capacitor (e.g., Murata GRM21BR71A106KE51L) is validated for 1.8-V/1-A operation. Larger values improve transient response but require verification of loop stability per Table 4 in the datasheet.
Can the TLV62568DRLR operate with a 2.5-V input and 1.8-V output?
Yes, the TLV62568DRLR supports 2.5-V minimum input and regulates 1.8-V output across its full 0–1-A load range. At light loads, Power Save Mode maintains >85% efficiency; at full load, efficiency reaches ~92% (per Figure 7). Ensure the inductor DCR and high-side RDS(on) allow sufficient headroom for 100% duty-cycle operation if VIN approaches VOUT.
What package type and dimensions does the TLV62568DRLR use?
The TLV62568DRLR uses the SOT563-6 package: 1.60 mm × 1.60 mm body size, 0.55-mm maximum height, 0.5-mm pin pitch. It features an exposed thermal pad (non-electrical) for improved heat dissipation. This package is distinct from SOT23-5 (TLV62568DBV) and SOT23-6 (TLV62568PDDC) variants and is not pin-compatible with them.
