Product details
Overview
TLV62569PDRLT from Texas Instruments is a 2-A synchronous step-down DC-DC buck converter in SOT563-6 package, featuring 1.5-MHz fixed-frequency PWM operation, Power Save Mode for light-load efficiency, and integrated 100-mΩ/60-mΩ MOSFETs. It delivers regulated 1.8-V output at up to 2 A from 2.5–5.5-V input, with power good (PG) output and thermal shutdown-used in network video cameras and wireless routers.
For engineers reviewing the TLV62569PDRLT datasheet, TLV62569PDRLT pinout, TLV62569PDRLT application, or TLV62569PDRLT equivalent, key selection criteria include its 95% peak efficiency at 1.8 V/2 A, 35-µA quiescent current, adjustable feedback (0.6 V reference), 100% duty-cycle low-dropout capability, and PG pin logic compatibility with rail sequencing.
Technical Context
The TLV62569PDRLT employs adaptive off-time peak-current control with fixed 1.5-MHz switching frequency under medium-to-heavy loads and transitions automatically to Power Save Mode at light loads to sustain high efficiency. Its internal soft-start limits inrush current during startup, and it supports pre-biased output startup.
It integrates over-current protection via high-side switch current limiting (2.5 A typical), thermal shutdown (150°C rising threshold), and under-voltage lockout (2.45 V nominal with 100-mV hysteresis). The PG pin provides open-drain power-good signaling referenced to 95% (rising) and 90% (falling) of FB voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A maximum continuous output current-supports compact POL supplies for SoC cores and FPGAs. |
| Input Voltage Range | 2.5 V to 5.5 V-compatible with single-cell Li-ion, USB, and 3.3-V/5-V rails. |
| Switching Frequency | 1.5 MHz typical-enables small external components (e.g., 2.2-µH inductor, 10-µF ceramic output cap). |
| Quiescent Current | 35 µA-minimizes standby power loss in always-on IoT and surveillance devices. |
| Feedback Reference | 0.6 V ±2%-allows precise output regulation from 0.6 V to VIN using external resistor divider. |
| Peak Efficiency | 95% at 1.8 V/2 A, 5-V input-reduces thermal load in space-constrained enclosures. |
| Power Good Threshold | Rising at 95% VFB, falling at 90% VFB-enables reliable power-rail sequencing in multi-converter systems. |
| Thermal Shutdown | 150°C junction temperature rising threshold-protects against sustained overload or poor PCB thermal design. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6-mm pitch), thermally enhanced for high-density layouts with exposed pad (not electrically connected per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 5) | Enable logic input | Active-high digital control: ≥0.95 V enables regulation; ≤0.85 V forces shutdown (<2 µA IQ). |
| GND (Pin 2) | Power ground | Main return path for high-current SW node and internal circuitry-requires low-impedance PCB connection to minimize noise and thermal rise. |
| SW (Pin 4) | Switch node | Connects to inductor and internal high/low-side MOSFETs-critical high-dv/dt node requiring short, wide trace routing. |
| VIN (Pin 3) | Input supply | 2.5–5.5 V input rail-must be decoupled with ≥4.7-µF ceramic capacitor placed adjacent to pin. |
| FB (Pin 1) | Feedback input | Monitors output via resistor divider; 0.6-V reference sets VOUT = 0.6 × (1 + R1/R2)-sensitive signal requiring noise-isolated trace routing. |
| PG (Pin 6) | Power good output | Open-drain status indicator-requires external pull-up (≤5.5 V); asserts high-Z when VOUT ≥95% target, drives low when ≤90% target. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically reduces switching frequency at light loads to maintain >85% efficiency down to 10-mA output-extends battery life in always-on edge devices. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + DCRL)-supports regulation near input rail (e.g., 3.3-V input → 3.0-V output @ 1 A). |
| Integrated MOSFETs | 100-mΩ high-side / 60-mΩ low-side RDS(on)-eliminates external switches and reduces BOM count and layout area. |
| Internal Soft Start | 900-µs ramp time-prevents inrush current into large output capacitors and avoids brownout on weak sources like coin cells. |
| Robust Protection Suite | Includes over-current limit (2.5 A), thermal shutdown (150°C), UVLO (2.45 V), and PG fault detection-reduces need for external supervision ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62568PDRLT | No PG pin; 1-A output current rating; identical SOT563-6 footprint and FB reference. | Lacks rail-sequencing capability; limited to lower-power SoCs or peripherals. | Select when PG functionality is unnecessary and output current ≤1 A-reduces cost without layout change. |
| TPS62865DRLR | Higher 4-A rating; 2.5-MHz switching; integrated compensation; smaller 1.2-mm × 0.8-mm WCSP package. | Better suited for next-gen high-performance processors; requires re-layout due to different pinout and package. | Choose for future-proof designs needing >2-A headroom or tighter size constraints-accepts higher BOM and layout effort. |
Compared with TLV62569PDRLT, TLV62568PDRLT offers pin-compatible simplification without PG or 2-A capability, while TPS62865DRLR delivers higher performance at the cost of non-interchangeable packaging and layout redesign-making TLV62569PDRLT optimal for cost-sensitive, PG-dependent 2-A POL applications.

FAQ
What is the maximum output current supported by the TLV62569PDRLT?
The TLV62569PDRLT supports a continuous output current of up to 2 A under recommended operating conditions (TJ ≤125°C, proper PCB thermal design). Its current limit is specified at 2.5 A typical, providing margin for transient peaks. Derating is required above 85°C ambient or with insufficient copper area-consult thermal metrics (RθJB = 27.0°C/W) for layout guidance. The TLV62569PDRLT maintains regulation across this range with <±2% load regulation.
Does the TLV62569PDRLT include a power good (PG) output?
Yes, the TLV62569PDRLT includes an open-drain power good (PG) output on Pin 6. It asserts high-impedance when VFB ≥95% of 0.6 V (i.e., ≥0.57 V), and pulls low (≤0.4 V at 1 mA sink) when VFB ≤90% (≤0.54 V). This PG signal is used for rail sequencing and system monitoring. The TLV62569PDRLT marking "19E" confirms PG functionality per TI's device comparison table.
What package type and dimensions does the TLV62569PDRLT use?
The TLV62569PDRLT uses the SOT563-6 package: a 6-pin, 1.60 mm × 1.60 mm body with 0.6-mm lead pitch and exposed thermal pad (non-electrical). It is distinct from SOT23-5 (TLV62569DBV) and SOT23-6 (TLV62569PDDC) variants. The DRL suffix in TLV62569PDRLT explicitly denotes this compact, thermally optimized package per TI's orderable addendum.
How does the TLV62569PDRLT manage efficiency at light loads?
The TLV62569PDRLT automatically enters Power Save Mode (PSM) at light loads (typically <100 mA), reducing switching frequency and gate drive activity to maintain >85% efficiency down to 10 mA. This mode slightly increases output voltage ripple but avoids the efficiency cliff seen in forced-PWM converters. The TLV62569PDRLT's 35-µA quiescent current further minimizes no-load losses-critical for battery-backed surveillance systems.
Can the TLV62569PDRLT operate with a 2.5-V input and 1.8-V output?
Yes, the TLV62569PDRLT operates across the full 2.5–5.5-V input range and supports 1.8-V output with 2-A capability. At 2.5-V input, it achieves ~90% peak efficiency (per Figure D004) and enters 100% duty cycle mode only if VIN drops near VOUT + IOUT×(RDS(on)+DCRL). For 1.8-V/2-A output, TI recommends 2.2-µH inductor and 10-µF ceramic output capacitor-validated in the TLV62569PDRLT typical application schematic.
