Product details
Overview
TLV62568DBVR 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 2.5–5.5 V input range. It integrates 150 mΩ/100 mΩ high-/low-side MOSFETs and supports adjustable output voltage (0.6 V to VIN) for point-of-load regulation in space-constrained applications.
For engineers reviewing the TLV62568DBVR datasheet, TLV62568DBVR pinout, TLV62568DBVR application, or TLV62568DBVR equivalent, key selection criteria include light-load Power Save Mode operation, 35 µA quiescent current, 100% duty cycle low-dropout capability, and SOT-23-5 package compatibility with standard PCB layout practices.
Technical Context
The TLV62568DBVR uses adaptive off-time peak current control to maintain stable 1.5-MHz PWM operation across varying input (2.5–5.5 V), output (0.6–VIN), and load (0–1 A) conditions. Its internal soft-start limits inrush current during startup, while under-voltage lockout (2.45 V threshold) and thermal shutdown (150 °C) ensure robust system-level protection.
Unlike TLV62568P variants, TLV62568DBVR lacks a power-good (PG) output and uses a 5-pin SOT-23 package with EN, SW, GND, VIN, and FB terminals - omitting PG and NC pins found in 6-pin versions. It supports pre-biased start-up and operates in discontinuous conduction mode at light loads to sustain >85% efficiency down to 10 mA.
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 | 1 A continuous - sufficient for powering ARM Cortex-M microcontrollers, FPGA I/O banks, or sensor signal chains. |
| Switching Frequency | 1.5 MHz - enables use of small 2.2 µH inductors and 4.7–10 µF ceramic capacitors for compact, low-profile designs. |
| Quiescent Current | 35 µA - minimizes standby power loss in battery-powered devices such as network cameras and IoT edge nodes. |
| FET RDS(on) | 150 mΩ (HS) / 100 mΩ (LS) - reduces conduction losses and thermal rise at full load, supporting >90% efficiency at 0.5 A. |
| Feedback Voltage | 0.6 V ±2% - sets precise output regulation via external resistor divider; enables 1.8 V output with 200 kΩ/100 kΩ divider. |
| Shutdown Current | <2 µA - ensures negligible battery drain when disabled via EN pin logic-low signal. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 2.80 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable logic input | Active-high digital control; must be pulled to VIN or grounded - floating state disables device and increases risk of erratic startup. |
| GND | Power ground reference | Primary return path for high-current switch node and feedback circuit; requires low-impedance connection to PCB ground plane. |
| SW | Switch node | Connects internally to both FETs and externally to inductor; carries high di/dt pulses - demands short, wide copper routing to minimize EMI and voltage overshoot. |
| VIN | Input power supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic decoupling within 3 mm of pin to suppress high-frequency ripple and stabilize regulation. |
| FB | Feedback input | High-impedance node sensing output voltage via resistor divider; sensitive to noise - must be routed away from SW and power traces. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically engages below ~100 mA load to reduce switching frequency and maintain >85% efficiency - critical for always-on IoT sensors. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + DCRL) - supports 1.8 V output from 2.5 V input at 1 A without regulation loss. |
| Internal Soft Start | 700 µs ramp time limits inrush current to <1.2 A - prevents brownout of weak sources like coin cells or aging batteries. |
| Overcurrent Protection | Peak current limit at 1.5 A - protects against short-circuit faults and inductor saturation while allowing safe transient overload. |
| Thermal Shutdown | 150 °C trip with 20 °C hysteresis - safeguards silicon integrity during sustained overload or poor PCB thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569DBVR | Pin-to-pin compatible with identical SOT-23-5 package and electrical specs, but includes integrated power-good (PG) output. | Required where rail sequencing or fault monitoring is needed - e.g., multi-rail FPGA power systems. | Select TLV62569DBVR only if PG functionality is required; TLV62568DBVR offers lower BOM cost and simpler layout when PG is unused. |
| TPS62865DRLR | 4-V to 16-V input, 3-A output, 2.25-MHz switching, QFN-12 package - higher voltage/current rating and smaller 1.2-mm height. | Suitable for 12 V intermediate bus applications requiring >1 A, such as PoE-powered access points or motor drives. | Choose TPS62865DRLR for higher input voltage or current needs; TLV62568DBVR remains optimal for 2.5–5.5 V, ≤1 A, space-limited designs. |
Compared with TLV62568DBVR, TLV62569DBVR adds PG functionality without altering size or efficiency, while TPS62865DRLR shifts to higher voltage/current capability and different packaging - making TLV62568DBVR the most cost-effective, compact solution for sub-1-A 3.3/5 V rail conversion.

FAQ
What is the maximum output current supported by the TLV62568DBVR?
The TLV62568DBVR delivers up to 1 A of continuous output current under recommended operating conditions (TJ ≤ 125 °C, proper PCB thermal design). Its internal 150 mΩ/100 mΩ MOSFETs and thermal shutdown at 150 °C enable reliable 1-A operation in SOT-23-5 packages when using adequate copper pour and airflow.
Does the TLV62568DBVR include a power-good (PG) output?
No, the TLV62568DBVR does not include a power-good output. That feature is exclusive to TLV62568P variants (e.g., TLV62568PDDC, TLV62568PDRL) which use 6-pin packages. The TLV62568DBVR uses a 5-pin SOT-23 package with EN, SW, GND, VIN, and FB - no PG or NC pin is present.
What input voltage range is supported by the TLV62568DBVR?
The TLV62568DBVR supports an input voltage range of 2.5 V to 5.5 V. Its under-voltage lockout activates at 2.45 V (typical), ensuring stable operation across single-cell Li-ion (2.7–4.2 V), USB 5 V, and regulated 3.3 V supplies without external supervision.
How does the TLV62568DBVR manage efficiency at light loads?
The TLV62568DBVR automatically enters Power Save Mode (PSM) at light loads (<100 mA), reducing switching frequency and quiescent current to 35 µA. This maintains >85% efficiency down to 10 mA, unlike forced-PWM converters that suffer steep efficiency drop-offs below 10% load.
Can the TLV62568DBVR start up into a pre-biased output capacitor?
Yes, the TLV62568DBVR supports pre-biased start-up: it detects existing output voltage and ramps the FB node to regulate smoothly to the target level without reverse current or output overshoot - essential for hot-swap and multi-rail sequencing applications.
