Product details
Overview
TLV62568DRLT from Texas Instruments is a 1-A synchronous step-down buck DC-DC converter in SOT563-6 package, featuring 2.5–5.5 V input range, adjustable 0.6–VIN output, 1.5-MHz fixed-frequency PWM operation, Power Save Mode for light loads, and integrated 150 mΩ/100 mΩ MOSFETs - deployed in network video cameras and set-top boxes for high-efficiency point-of-load regulation.
For engineers reviewing the TLV62568DRLT datasheet, TLV62568DRLT pinout, TLV62568DRLT application, or TLV62568DRLT equivalent, key selection criteria include verified 95% peak efficiency at 1 A, 35 µA quiescent current, 100% duty cycle low-dropout capability, thermal shutdown at 150°C, and confirmed SOT563 footprint compatibility with layout-sensitive POL designs.
Technical Context
The TLV62568DRLT employs adaptive off-time peak-current control to maintain ~1.5-MHz switching frequency across input (2.5–5.5 V), output (0.6–VIN), and load (0–1 A) variations. Its internal soft-start limits inrush current during startup, and it supports pre-biased output startup without voltage reversal.
It operates in PWM mode at medium-to-heavy loads and automatically transitions to Power Save Mode at light loads to sustain >85% efficiency down to 10 mA. The device integrates overcurrent protection (1.5-A peak switch limit), UVLO (2.45-V threshold with 100-mV hysteresis), and thermal shutdown (150°C rising / 130°C falling).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1 A continuous - supports single-rail digital ICs like SoCs and FPGAs requiring stable 1.8 V or 3.3 V POL supply. |
| 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 pre-regulation. |
| Switching Frequency | 1.5 MHz - enables use of small 2.2-µH inductors and 10-µF ceramic output capacitors for compact PCB area. |
| Peak Efficiency | 95% at 1 A, VIN = 5 V, VOUT = 1.8 V - reduces thermal load in enclosed consumer enclosures and extends battery runtime. |
| Quiescent Current | 35 µA - minimizes standby power loss in always-on applications such as security camera motion detection circuits. |
| Feedback Reference | 0.6 V ±2% - allows precise output setting via standard resistor dividers; enables 1.2 V, 1.8 V, 2.5 V, and 3.3 V configurations. |
| Thermal Shutdown | 150°C junction temperature - protects against sustained overload or poor heatsinking in unventilated industrial housings. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.55-mm pitch); thermally enhanced bottom-side pad; 6-pin configuration with NC pin (Pin 6) usable as optional output connection or left floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 5) | Enable logic input | Active-high control: ≥0.95 V enables regulation; ≤0.85 V disables device and reduces VIN current to <2 µA. |
| GND (Pin 2) | Power ground | Main return path for high-frequency switch current; must be connected directly to low-impedance PCB ground plane. |
| SW (Pin 4) | Switch node | Connects to inductor and internal high/low-side MOSFETs; requires short, wide trace to minimize EMI and voltage ringing. |
| VIN (Pin 3) | Input power supply | Accepts 2.5–5.5 V; requires local 4.7-µF ceramic capacitor placed within 2 mm of pin to suppress high-frequency ripple. |
| FB (Pin 1) | Feedback input | Monitors output via resistor divider; 0.6-V reference sets VOUT = 0.6 × (1 + R1/R2); sensitive to noise - route away from SW. |
| NC (Pin 6) | No connection | Not internally bonded; may be tied to VOUT for minor noise reduction or left unconnected per TI recommendation. |
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 × (150 mΩ + inductor DCR); sustains regulation when VIN approaches VOUT (e.g., 1.85 V → 1.8 V). |
| Integrated MOSFETs | 150 mΩ high-side + 100 mΩ low-side RDS(on) - eliminates external FETs and gate drivers, reducing BOM count and layout complexity. |
| Internal Soft Start | 900-µs ramp time prevents inrush current surges into large output caps; avoids brownout on weak input sources like coin cells. |
| Robust Protection Suite | Includes cycle-by-cycle overcurrent limiting (1.5-A peak), thermal shutdown (150°C), UVLO (2.45 V), and open-drain PG (on TLV62568P variants only). |
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 |
|---|---|---|---|
| TLV62569DRLT | Same SOT563-6 package, identical pinout, but includes Power Good (PG) output - TLV62568DRLT lacks PG functionality. | Required where rail sequencing or fault monitoring is needed (e.g., multi-rail FPGA systems); TLV62568DRLT suffices for standalone POL with no sequencing. | Select TLV62569DRLT if PG signal is required for system-level power management; otherwise TLV62568DRLT offers lower cost and same performance for basic regulation. |
| TPS62865DRLR | Higher 3-A rating, 2.5–5.5-V input, 1.8-V fixed output, 2-MHz switching, but uses 1.2-mm × 1.6-mm WSON-6 package - not pin-compatible. | Used where higher current headroom or tighter output tolerance (±0.5%) is required; TLV62568DRLT fits legacy layouts constrained to SOT563. | Choose TPS62865DRLR only if design requires >1 A or stricter VOUT accuracy; TLV62568DRLT remains optimal for 1-A, cost-sensitive, space-constrained applications. |
Compared with TLV62568DRLT, TLV62569DRLT adds PG functionality without changing footprint or electrical specs, while TPS62865DRLR delivers higher current in a smaller but non-interchangeable package - making TLV62568DRLT the preferred choice for validated 1-A SOT563 designs requiring minimal BOM change.

FAQ
What is the maximum output current supported by the TLV62568DRLT?
The TLV62568DRLT is rated for continuous 1-A output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5–5.5 V). Peak switch current limit is 1.5 A, and thermal performance depends on PCB copper area and airflow. Derating is required above 85°C ambient or with insufficient thermal vias.
Does the TLV62568DRLT include a Power Good (PG) output?
No, the TLV62568DRLT does not include a Power Good output. That feature is present only in the TLV62568P variants (e.g., TLV62568PDRLT). The TLV62568DRLT has an NC (no-connect) pin at position 6, whereas TLV62568PDRLT uses that pin as open-drain PG with 95%/90% VOUT thresholds.
What package type and dimensions does the TLV62568DRLT use?
The TLV62568DRLT uses the SOT563-6 package: 1.60 mm × 1.60 mm body size, 0.55-mm lead pitch, and thermally enhanced exposed pad. It is distinct from SOT23-5 (TLV62568DBVT) and SOT23-6 (TLV62568PDDCT) variants - pinout and thermal metrics differ.
Can the TLV62568DRLT operate with a 2.5-V input and 1.8-V output at full 1-A load?
Yes, the TLV62568DRLT supports 2.5-V input to 1.8-V output at 1-A load using 100% duty cycle mode. Efficiency remains >88% under these conditions, and dropout is determined by IOUT × (150 mΩ + inductor DCR). Layout must minimize trace resistance to avoid excessive voltage drop.
How does Power Save Mode affect output voltage accuracy in the TLV62568DRLT?
In Power Save Mode, the TLV62568DRLT reduces switching frequency and may allow slight output voltage rise (typically <2% above nominal) due to discontinuous conduction. This is mitigated by increasing output capacitance (e.g., 22 µF instead of 10 µF) or adding a feed-forward capacitor (C3 = 6.8 pF) across R2 in the feedback divider.
