Product details
Overview
TLV62569APDRLR 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 TLV62569APDRLR datasheet, TLV62569APDRLR pinout, TLV62569APDRLR application, or TLV62569APDRLR equivalent, key selection criteria include its SOT563 package footprint, 100 mΩ/60 mΩ internal FET RDS(on), 0.6 V feedback reference, thermal shutdown at 150 °C, and PG open-drain sink capability of 2 mA - all critical for reliable POL supply design.
Technical Context
The TLV62569APDRLR employs peak-current-mode control with adaptive off-time modulation, maintaining stable 1.5-MHz switching across input (2.5–5.5 V), output (0.6–VIN), and load (0–2 A) variations. Its architecture supports 100% duty cycle operation for low-dropout regulation under high-VOUT/low-VIN conditions.
It integrates soft-start (0.9 ms), overcurrent protection (3 A switch current limit), UVLO (2.45 V threshold with 100 mV hysteresis), and thermal shutdown (150 °C rising / 130 °C falling). The PG pin provides rail-valid status with 95% VFB activation and 90% VFB deactivation thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A continuous - supports high-density POL rails for SoCs and FPGAs without external current boosting. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB 5 V, and 3.3 V/5 V system rails. |
| Switching Frequency | 1.5 MHz typical - enables use of small 1.0 µH inductors and reduces EMI filtering burden. |
| Feedback Reference | 0.6 V ±2% - allows precise adjustable output from 0.6 V to VIN using standard resistor dividers. |
| Efficiency Peak | 95% at 5 VIN/1.8 VOUT/1 A - minimizes thermal load in thermally constrained enclosures. |
| RDS(on) | 100 mΩ (HS) / 60 mΩ (LS) - reduces conduction losses and improves light-load efficiency vs. discrete solutions. |
| Shutdown Current | <2 µA - preserves battery life in always-on or low-power wake-up applications. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height), thermally enhanced for high-current DC-DC conversion in ultra-compact layouts.
| 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 high-current SW node and internal circuitry; requires low-impedance PCB plane connection. |
| VIN (Pin 3) | Input power supply | Accepts 2.5–5.5 V; must be decoupled with ≥4.7 µF ceramic capacitor placed adjacent to pin. |
| SW (Pin 4) | Switch node | Connects to inductor and high-side/low-side FETs; carries high di/dt; requires short, wide trace routing. |
| EN (Pin 5) | Enable logic input | Active-high (VIH ≥1.2 V); must be terminated - floating EN causes undefined operation. |
| PG (Pin 6) | Power-good open-drain output | Signals valid regulation (high-Z when VFB ≥95% ref; pulled low when VFB ≤90% ref); requires external pull-up ≤5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM operation | Eliminates mode-hopping noise; ensures consistent 1.5-MHz ripple frequency for predictable EMI filtering. |
| 100% duty cycle mode | Enables dropout as low as IOUT × (RDS(on) + DCRL); sustains regulation even when VIN ≈ VOUT. |
| Integrated power-good (PG) | Provides sequenced enable/disable signaling for multi-rail systems without external monitoring circuitry. |
| Thermal shutdown with hysteresis | Shuts down at 150 °C junction; resumes at 130 °C - prevents thermal runaway while enabling automatic recovery. |
| Internal soft-start | 0.9 ms ramp time limits inrush current into output capacitors, protecting input sources and downstream loads. |
Applications
| Enterprise SSD Power Rail | IP Network Camera Core Supply |
|---|---|
Use Scenario: Powers NVMe controller and NAND flash interface in 2.5-inch enterprise SSDs with tight thermal and board-area constraints. IC Role / Device Role / Timing Role: Primary 1.8 V/2 A POL regulator; replaces discrete buck controllers requiring external MOSFETs and compensation.

IC Role / Device Role / Timing Role: Secondary 1.8 V POL stage after primary 5 V DC-DC; synchronized startup via PG-to-EN chaining. Use Value: Forced PWM ensures clean 1.5-MHz ripple avoids interference with analog video signal paths; PG output enables safe power sequencing. |
| Wireless Router Baseband IC Supply | STB/DVR SoC Core Rail |
Use Scenario: Delivers stable 1.8 V to Wi-Fi 6 baseband processors (e.g., QCA9984) in compact dual-band routers with limited airflow. IC Role / Device Role / Timing Role: High-efficiency buck converter with integrated FETs; operates continuously under bursty RF transmit loads. Use Value: 2 A rating handles CPU + RF peak currents; 1.5 MHz switching allows use of 1.0 µH inductor, reducing solution height to <1.2 mm. |
Use Scenario: Powers ARM-based media SoC cores in set-top boxes where standby power budget is <100 mW. IC Role / Device Role / Timing Role: Main core voltage regulator; enabled only during active playback; PG confirms rail readiness before SoC boot. Use Value: <2 µA shutdown current meets stringent Energy Star standby requirements; 0.6 V FB reference enables accurate 1.2 V/1.5 V/1.8 V scaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569ADRL | No PG pin (NC on Pin 6); identical electrical specs and SOT563 package. | Used where power sequencing is handled externally or unnecessary. | Select TLV62569ADRL if PG functionality is unused - eliminates need for pull-up resistor and simplifies layout. |
| TPS6286518ARQYR | Higher 4-A rating, 2.5–5.5 V input, 1.8 V fixed output, 2.2-MHz switching, no PG pin. | Targets higher-current applications; lacks PG but offers tighter output tolerance (±1%) and lower quiescent current (1.2 µA). | Choose TPS6286518ARQYR when >2 A is required or when fixed 1.8 V output suffices and PG is not needed. |
Compared with TLV62569ADRL, TLV62569APDRLR adds verified PG signaling for system-level sequencing, while TPS6286518ARQYR trades PG for higher current and fixed-output simplicity - making TLV62569APDRLR optimal for 2-A POL with rail-status monitoring.

FAQ
What is the maximum output current capability of the TLV62569APDRLR?
The TLV62569APDRLR delivers up to 2 A of continuous output current at 1.8 V with proper thermal management. Its internal high-side and low-side FETs feature RDS(on) values of 100 mΩ and 60 mΩ respectively, enabling this rating within the 2.5–5.5 V input range and SOT563 package thermal limits. Derating applies above 85 °C ambient.
Does the TLV62569APDRLR support adjustable output voltages?
Yes, the TLV62569APDRLR supports adjustable output voltages from 0.6 V to VIN using an external resistor divider connected to the FB pin. Its precise 0.6 V ±2% internal reference enables accurate regulation - for example, a 200 kΩ/100 kΩ divider sets 1.8 V output. Feed-forward capacitor C3 (10 pF) may be added to improve transient response.
What is the function of the PG pin on the TLV62569APDRLR?
The PG (power-good) pin on the TLV62569APDRLR is an open-drain output that signals valid regulation: it goes high-impedance when VFB ≥95% of 0.6 V (i.e., ≥0.57 V), and pulls low (≤0.4 V at 2 mA sink) when VFB ≤90% (≤0.54 V). It requires an external pull-up resistor to ≤5.5 V and is used for power sequencing in multi-rail systems.
Can the TLV62569APDRLR operate with 100% duty cycle?
Yes, the TLV62569APDRLR supports 100% duty cycle operation to minimize dropout voltage. In this mode, the high-side FET remains fully on and the low-side FET is off, allowing regulation even when input voltage approaches output voltage. Minimum input is calculated as VOUT + IOUT × (RDS(on) + DCRL), enabling ultra-low headroom designs.
What package type and dimensions does the TLV62569APDRLR use?
The TLV62569APDRLR uses the SOT563-6 package: a 6-pin, surface-mount, thermally enhanced package measuring 1.60 mm × 1.60 mm (nominal body size) with 0.6 mm maximum height. Its pinout (FB-GND-VIN-SW-EN-PG) and exposed pad variant support efficient heat dissipation in high-density PCB layouts.
