Product details
Overview
TLV62569ADRLR 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 100 mΩ/60 mΩ MOSFETs - used in point-of-load power supplies for IP cameras and SSDs.
For engineers reviewing the TLV62569ADRLR datasheet, TLV62569ADRLR pinout, TLV62569ADRLR application, or TLV62569ADRLR equivalent, key selection criteria include its SOT563 package footprint, 95% peak efficiency at 2 A, 0.6 V feedback reference, thermal shutdown at 150 °C, and NC/PG pin configuration distinguishing it from PG-equipped variants.
Technical Context
The TLV62569ADRLR 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 high-side and low-side FETs enable 100% duty-cycle operation for ultra-low dropout.
It integrates soft-start (0.9 ms), under-voltage lockout (2.45 V threshold, 100 mV hysteresis), overcurrent protection (3 A switch limit), and thermal shutdown (150 °C rising, 130 °C falling). The NC pin (Pin 6) is unconnected - not power-good - enabling simplified layout versus TLV62569APDRL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A continuous - supports high-density POL rails for SSD controllers and network camera SoCs. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB-powered, and 3.3 V/5 V system rails. |
| Switching Frequency | 1.5 MHz typical - enables compact 1.0 µH inductor and small ceramic capacitors (4.7 µF/22 µF). |
| Feedback Reference | 0.6 V ±2% - sets output via external resistor divider; enables adjustable outputs from 0.6 V to VIN. |
| Efficiency Peak | 95% at 2 A, 5 VIN/1.8 VOUT - minimizes thermal load in space-constrained embedded enclosures. |
| RDS(on) | 100 mΩ (HS) / 60 mΩ (LS) - reduces conduction loss and improves light-load regulation vs. discrete FET solutions. |
| Shutdown Current | ≤2 µA - preserves battery life in always-on IoT edge devices during deep sleep modes. |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6 mm height) with wettable flanks; thermally enhanced for PCB copper pour attachment on Pin 2 (GND) and optional thermal connection to Pin 6 (NC).
| 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 input/output currents; must be low-impedance plane connection for stability. |
| VIN (Pin 3) | Input supply | Accepts 2.5–5.5 V; requires local 4.7 µF ceramic capacitor placed adjacent to minimize high-frequency noise. |
| 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; 1.2 V min VIH ensures compatibility with 1.8 V/3.3 V GPIO; must not float. |
| NC (Pin 6) | No connection | Unbonded pad; may be tied to GND or VOUT for thermal relief - no electrical function. |
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) + DCRL) - critical for battery-powered systems near end-of-discharge. |
| Integrated soft-start | 0.9 ms ramp time prevents inrush current into 22 µF output capacitance - avoids brownout of upstream regulators. |
| Thermal shutdown | Auto-recovery at 130 °C junction temperature - protects against sustained overload without manual reset. |
| Low RDS(on) switches | 100 mΩ HS / 60 mΩ LS - reduces conduction loss by >30% vs. comparable 1.5 A buck converters in same package. |
Applications
| IP Network Camera Power Rail | Solid-State Drive (SSD) Core Supply |
|---|---|
|
Use Scenario: Powers image signal processor (ISP) and memory interface in compact IP cameras with 3.3 V or 5 V input rails. IC Role / Device Role / Timing Role: Primary 1.8 V/2 A POL regulator delivering clean, ripple-controlled voltage to high-speed SerDes and DDR interfaces.

IC Role / Device Role / Timing Role: Compact SOT563 DC-DC converter replacing larger QFN solutions to meet 12 mm × 12 mm module size constraints. Use Value: 1.6 mm × 1.6 mm footprint and integrated FETs eliminate external MOSFET layout complexity and gate-drive components. |
Use Scenario: Provides regulated 1.8 V rail for HDMI PHY and video decoder logic in set-top boxes with multi-rail power architecture. IC Role / Device Role / Timing Role: Secondary POL converter sequenced after main 3.3 V rail using EN pin control. Use Value: 0.9 ms soft-start enables precise power-up timing coordination with other rails - prevents latch-up in mixed-signal 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 |
|---|---|---|---|
| TLV62569APDRL | Includes open-drain PG pin (2 mA sink); identical electrical specs and pinout except Pin 6 = PG instead of NC. | Required where power-good sequencing or fault reporting is needed (e.g., multi-rail FPGA systems). | Select TLV62569APDRL only if PG functionality is mandatory; TLV62569ADRLR avoids pull-up resistor and routing overhead. |
| TPS6286518ARQYR | Higher 4 A rating, 2.5 V–5.5 V input, 1.8 V fixed output, 2.2 MHz fSW, 0.55 V ref; QFN-12 package (2.0 mm × 2.0 mm). | Better suited for higher-current or space-tolerant designs; lacks NC/PG flexibility and forced-PWM consistency. | Choose TPS6286518ARQYR when >2 A capability or tighter output tolerance (±1%) is required - not drop-in compatible due to package and pin count. |
Compared with TLV62569APDRL, TLV62569ADRLR saves BOM cost and layout area by omitting PG circuitry; versus TPS6286518ARQYR, it offers smaller footprint and deterministic PWM but lower current headroom and looser output accuracy.

FAQ
What is the maximum output current capability of the TLV62569ADRLR?
The TLV62569ADRLR delivers up to 2 A continuous output current under recommended operating conditions (TJ ≤ 125 °C, 2.5–5.5 V input). Its 3 A switch current limit provides headroom for transient peaks, but sustained operation above 2 A risks thermal shutdown. Derating is required above 85 °C ambient per the RθJA = 142.8 °C/W thermal metric.
Does the TLV62569ADRLR have a power-good (PG) output?
No, the TLV62569ADRLR does not include a power-good output. Pin 6 is designated NC (no connection), unlike the TLV62569APDRL variant which uses Pin 6 as an open-drain PG pin. If PG functionality is required, TLV62569APDRL is the direct alternative - otherwise, TLV62569ADRLR simplifies design by eliminating the need for a pull-up resistor and associated routing.
What is the feedback reference voltage of the TLV62569ADRLR?
The TLV62569ADRLR has a precision internal feedback reference voltage of 0.6 V ±2% (0.588 V to 0.612 V) at TJ = 25 °C. This reference is used with an external resistor divider (e.g., R1 = 200 kΩ, R2 = 100 kΩ) to set output voltages from 0.6 V to VIN. The FB pin leakage current is only 10 nA, minimizing divider error.
Can the TLV62569ADRLR operate with a 2.5 V input and 1.8 V output?
Yes, the TLV62569ADRLR supports 2.5 V to 5.5 V input and can regulate 1.8 V output across its full load range. At 2.5 VIN/1.8 VOUT, it operates in 100% duty cycle mode when necessary - maintaining regulation down to VIN = VOUT + IOUT × (RDS(on) + DCRL). Efficiency remains >85% at 2 A under these conditions.
What package type and dimensions does the TLV62569ADRLR use?
The TLV62569ADRLR is housed in a SOT563-6 package measuring 1.60 mm × 1.60 mm × 0.6 mm nominal body size. It features wettable flanks for automated optical inspection (AOI) and supports thermal enhancement via solder connection of Pin 2 (GND) and optionally Pin 6 (NC) to PCB copper pours.
