Product details
Overview
TLV62568APDRLT from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 2 A output current at 1.8 V, operating from 2.5 V to 5.5 V input, with forced PWM mode, 1.5-MHz switching frequency, and integrated power good (PG) output. It targets compact point-of-load regulation in space-constrained embedded systems.
For engineers reviewing the TLV62568APDRLT datasheet, TLV62568APDRLT pinout, TLV62568APDRLT application, or TLV62568APDRLT equivalent, key selection criteria include its SOT563 package footprint, 95% peak efficiency at 2 A, 0.6 V feedback reference, thermal shutdown protection, and PG open-drain output for rail sequencing.
Technical Context
The TLV62568APDRLT uses peak-current-mode control with adaptive off-time 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 100 mΩ high-side and 60 mΩ low-side MOSFETs enable high-efficiency operation without external drivers.
It supports 100% duty-cycle low-dropout mode, soft-start (0.9 ms), under-voltage lockout (2.45 V threshold, 100 mV hysteresis), and overcurrent protection via high-side current sensing. The PG pin asserts low when FB falls below 90% of nominal, sinking up to 2 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A maximum continuous - supports single-rail POL for FPGA I/O, microcontroller cores, or SSD controllers. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with Li-ion, USB, and 3.3 V/5 V system rails without pre-regulation. |
| Feedback Reference | 0.6 V ±2% - enables precise adjustable output from 0.6 V to VIN using standard resistor dividers. |
| Switching Frequency | 1.5 MHz typical - allows use of small 1.0 µH inductors and 22 µF ceramic output capacitors. |
| Peak Efficiency | 95% at 5 VIN/1.8 VOUT/2 A - minimizes thermal stress and extends battery runtime in portable designs. |
| Power Good Output | Open-drain PG with 2 mA sink capability - enables reliable power sequencing and fault monitoring in multi-rail systems. |
| Thermal Shutdown | 150 °C rising / 130 °C falling threshold - provides self-protection during overload or poor PCB thermal design. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height), thermally enhanced with exposed pad (connected to GND). Designed for high-density layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback input | Connects to resistor divider; regulates output by comparing divided VOUT to 0.6 V internal reference. |
| GND (Pin 2) | Power ground | Main return path for input/output currents and IC bias; must be low-impedance connection to PCB ground plane. |
| VIN (Pin 3) | Input supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic capacitor placed adjacent to minimize input ripple and EMI. |
| SW (Pin 4) | Switch node | Drives external 1.0 µH inductor; high dv/dt node requiring short, wide trace and separation from sensitive signals. |
| EN (Pin 5) | Enable input | Active-high logic control (VIH ≥1.2 V); must be terminated-floating EN causes undefined operation. |
| PG (Pin 6) | Power good output | Open-drain status signal; requires external pull-up ≤5.5 V; used for sequencing or system reset assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM operation | Eliminates frequency modulation at light loads-ensures consistent EMI profile and low output voltage ripple. |
| 100% duty-cycle mode | Enables dropout as low as IOUT × (RDS(on) + LDCR) - critical for battery-powered systems near end-of-discharge. |
| Internal soft-start | 0.9 ms ramp time - prevents inrush current into large output capacitors and avoids brownout on shared input rails. |
| Integrated protection | Includes overcurrent (2 A limit), thermal shutdown (150 °C), UVLO (2.45 V), and PG fault reporting - reduces external component count. |
| SOT563 package | 1.6 mm × 1.6 mm footprint with thermal pad - delivers 142.8 °C/W junction-to-ambient resistance for compact thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62568ADRL | No PG pin; identical electrical specs and pinout except Pin 6 is NC. | Lacks power sequencing capability; suitable only where rail coordination is handled externally. | Select TLV62568ADRL if PG functionality is unnecessary and BOM cost reduction is prioritized. |
| TLV62569APDRL | 2 A rated with same PG function but higher current limit (3 A) and different thermal derating curve. | Better suited for transient-heavy loads (e.g., burst-mode processors) due to higher switch current headroom. | Choose TLV62569APDRL when future-proofing for >2 A peak loads or tighter thermal margins are required. |
Compared with TLV62568ADRL, TLV62568APDRLT adds essential power-good signaling for system reliability; compared with TLV62569APDRL, it trades peak current headroom for tighter cost and thermal optimization at nominal 2 A operation.

FAQ
What is the maximum output current capability of the TLV62568APDRLT?
The TLV62568APDRLT delivers up to 2 A continuous output current at 1.8 V with 5 V input, as confirmed by TI's production datasheet SLVSE95B. Its current limit is fixed at 2 A (not adjustable), and thermal performance must be validated per PCB layout and ambient conditions-derating applies above 85 °C junction temperature.
Does the TLV62568APDRLT support adjustable output voltage?
Yes, the TLV62568APDRLT supports adjustable output voltage from 0.6 V to VIN using an external resistor divider on the FB pin. The internal 0.6 V reference has ±2% tolerance, and typical designs use R1 = 200 kΩ and R2 = 100 kΩ to set 1.8 V output, as shown in TI's reference schematic.
What is the function of the PG pin on the TLV62568APDRLT?
The PG (power good) pin on the TLV62568APDRLT is an open-drain output that goes high-impedance when VFB ≥95% of nominal and pulls low (≤0.4 V at 2 mA sink) when VFB ≤90%. It requires an external pull-up resistor ≤5.5 V and is used for power sequencing, system reset, or fault indication in multi-rail designs.
Can the TLV62568APDRLT operate with a 2.5 V input and 1.8 V output?
Yes, the TLV62568APDRLT operates across the full 2.5 V to 5.5 V input range and supports 1.8 V output at up to 2 A. At 2.5 VIN/1.8 VOUT, it enters 100% duty-cycle mode-verified in TI's datasheet Figure D019-and maintains regulation with appropriate inductor DCR and layout.
Is the TLV62568APDRLT pin-compatible with other devices in the TLV6256xA family?
Yes, the TLV62568APDRLT is pin-to-pin compatible with TLV62568ADRL, TLV62569ADRL, and TLV62569APDRL in the SOT563-6 package. Pin mapping (FB, GND, VIN, SW, EN, PG/NC) is identical; only functional differences (e.g., PG presence or current rating) distinguish them-no PCB redesign is needed for substitution within spec limits.
