Product details
Overview
TLV62569APDRLT 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 supplies in space-constrained embedded systems.
For engineers reviewing the TLV62569APDRLT datasheet, TLV62569APDRLT pinout, TLV62569APDRLT application, or TLV62569APDRLT equivalent, key selection criteria include its 2-A continuous output capability, SOT563 package footprint, PG open-drain functionality, 100 mΩ/60 mΩ internal FET RDS(on), and 0.6 V feedback reference for adjustable regulation.
Technical Context
The TLV62569APDRLT 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 forced PWM operation eliminates diode conduction mode, ensuring low output voltage ripple even at light loads.
It integrates protection features including thermal shutdown (150 °C trip), overcurrent limiting (3 A typical switch current limit), UVLO (2.45 V threshold with 100 mV hysteresis), and internal soft-start (0.9 ms). The PG pin provides open-drain status signaling referenced to 95% (rising) and 90% (falling) of nominal VFB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 2 A continuous - supports high-density POL rails for processors, FPGAs, and SSD controllers. |
| Input voltage range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB, and 3.3 V/5 V system rails. |
| Switching frequency | 1.5 MHz typical - enables use of small 1 µH inductors and ceramic capacitors for minimal board area. |
| Feedback reference | 0.6 V ±2% - allows precise output setting down to 0.6 V and up to VIN via resistor divider. |
| Efficiency peak | 95% at 5 VIN/1.8 VOUT/1 A - reduces thermal load and extends battery runtime in portable applications. |
| RDS(on) (HS/LS) | 100 mΩ / 60 mΩ - lowers conduction loss and improves full-load efficiency without external MOSFETs. |
| Shutdown current | ≤2 µA - preserves battery life during system sleep or standby modes. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height) with wettable flanks; thermally enhanced layout supports >2 W dissipation under proper PCB copper exposure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback input | Connects to resistor divider midpoint; regulates output by comparing against 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 | Drives external 1 µH inductor; carries high di/dt current - requires short, wide trace and minimized loop area. |
| EN (Pin 5) | Enable logic input | Active-high (≥1.2 V); disables device and reduces VIN current to ≤2 µA when pulled low or grounded. |
| PG (Pin 6) | Power good open-drain | Signals valid regulation (high-Z when VFB ≥95% ref; sinks ≤2 mA when VFB ≤90% ref); requires external pull-up ≤5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM operation | Eliminates discontinuous conduction mode (DCM), ensuring consistent 1.5 MHz switching and predictable EMI profile across all loads. |
| 100% duty cycle mode | Enables ultra-low dropout operation - maintains regulation when VIN approaches VOUT + IOUT×(RDS(on)+LDCR). |
| Integrated power good (PG) | Provides system-level rail sequencing and fault detection without external monitoring circuitry. |
| Internal soft-start | 0.9 ms ramp time limits inrush current, prevents input rail collapse, and avoids overstress on input capacitors and batteries. |
| Thermal and overcurrent protection | Auto-recovery thermal shutdown (150 °C trip) and cycle-by-cycle peak current limiting (3 A typical) ensure robustness under overload or ambient stress. |

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 (no connect) at Pin 6 instead of PG; identical electrical specs otherwise. | Lacks rail sequencing capability; unsuitable where power-good signaling is required for system safety or startup coordination. | Select TLV62569ADRL only if PG functionality is unused and cost minimization is prioritized. |
| TPS6286901RQYR | Higher 4-A output rating; 2.5–5.5 V input; 1.8-MHz switching; integrated PG; smaller 1.2-mm × 0.8-mm DSBGA package. | Better suited for higher-current applications; DSBGA requires more stringent assembly but offers lower thermal resistance. | Choose TPS6286901RQYR when >2 A headroom or tighter thermal budget is needed, accepting finer-pitch assembly requirements. |
Compared with TLV62569ADRL, TLV62569APDRLT adds essential power-good signaling for system-level reliability; compared with TPS6286901RQYR, it trades higher current capacity and smaller footprint for broader design familiarity, mature SOT563 assembly support, and proven field performance in consumer infrastructure.

FAQ
What is the maximum continuous output current of the TLV62569APDRLT?
The TLV62569APDRLT delivers up to 2 A continuous output current at 1.8 V with 5 V input and 25 °C ambient, verified across the full operating temperature range (–40 °C to 125 °C junction). Its 3 A typical switch current limit provides margin for transient peaks, and thermal derating follows JEDEC RθJA = 142.8 °C/W in standard DRL layout.
Does the TLV62569APDRLT support adjustable output voltage?
Yes, the TLV62569APDRLT supports adjustable output voltage from 0.6 V to VIN using an external resistor divider on the FB pin. Its precise 0.6 V ±2% internal reference enables accurate regulation - for example, a 1.8 V output is set with R1 = 200 kΩ and R2 = 100 kΩ, as confirmed in the TLV62569APDRLT typical application schematic.
What is the function of the PG pin on the TLV62569APDRLT?
The PG (power good) pin on the TLV62569APDRLT 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 sinks up to 2 mA when VFB ≤90% (i.e., ≤0.54 V). This enables rail sequencing and fault detection - a key differentiator versus the non-PG TLV62569ADRL variant.
Can the TLV62569APDRLT operate with a 2.5-V input and 1.8-V output?
Yes, the TLV62569APDRLT operates reliably with 2.5 V input and 1.8 V output. Its 100% duty cycle mode maintains regulation under low dropout conditions, and efficiency remains ≥85% at 1 A load per the D008 efficiency curve. Input UVLO (2.45 V) ensures clean startup without oscillation near the minimum input threshold.
What package type and thermal characteristics does the TLV62569APDRLT use?
The TLV62569APDRLT uses the SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height) with wettable flanks. Its junction-to-ambient thermal resistance is 142.8 °C/W (JEDEC standard), and junction-to-board is 28.9 °C/W - enabling >2 W power dissipation with adequate PCB copper area and thermal vias, as validated in TI's SLVSE95B datasheet.
