Product details
Overview
TLV62569DBVT from Texas Instruments is a 2-A synchronous step-down DC-DC buck converter in SOT23-5 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, used in compact POL supplies for network video cameras and wireless routers.
For engineers reviewing the TLV62569DBVT datasheet, TLV62569DBVT pinout, TLV62569DBVT application, or TLV62569DBVT equivalent, key selection considerations include its 35-µA quiescent current, 0.6-V feedback reference, 100% duty-cycle low-dropout capability, and absence of power-good (PG) output - distinguishing it from TLV62569P variants.
Technical Context
The TLV62569DBVT 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 internal soft-start limits inrush current during startup, and it supports pre-biased output startup.
It operates in PWM mode at medium-to-heavy loads and automatically transitions to Power Save Mode under light load to sustain >85% efficiency down to 10 mA. Protection features include overcurrent limiting (3 A typical), thermal shutdown (150°C), and UVLO (2.45 V nominal with 100-mV hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 2 A maximum continuous - supports single-rail 1.8-V/2-A POL for SoC or FPGA core supplies. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with Li-ion, USB, and 3.3-V/5-V system rails without external LDO pre-regulation. |
| Switching Frequency | 1.5 MHz typical - enables use of small 2.2-µH inductors and ceramic capacitors for space-constrained designs. |
| Feedback Reference | 0.6 V ±2% - allows precise adjustable output from 0.6 V to VIN using standard resistor dividers (e.g., R1=200 kΩ, R2=100 kΩ for 1.8 V). |
| Quiescent Current | 35 µA - minimizes standby power loss in battery-powered applications like portable surveillance cameras. |
| Efficiency Peak | 95% at 1.8 V/1 A, 5 V input - reduces thermal load and improves battery runtime versus older 85–90% converters. |
| Current Limit | 3 A typical - provides robust short-circuit and overload protection without requiring external current-sense circuitry. |
Pinout & Package
SOT23-5 (DBV) package: 2.90 mm × 2.80 mm body, single-row 5-pin surface-mount, thermally enhanced with exposed pad not present - requires standard SOT23-5 footprint and reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable logic input | Active-high digital control: ≥0.95 V enables regulation; ≤0.85 V disables device and reduces VIN current to <2 µA. |
| GND (Pin 2) | Power ground | Main return path for high-frequency switch current and analog reference - must connect directly to low-impedance PCB ground plane. |
| SW (Pin 3) | Switch node | Drives external inductor; carries high di/dt PWM waveform - requires short, wide trace and adjacent ground pour for EMI control. |
| VIN (Pin 4) | Input power supply | Accepts 2.5–5.5 V; requires local 4.7-µF ceramic capacitor placed within 3 mm of pin to suppress high-frequency ripple. |
| FB (Pin 5) | Feedback input | High-impedance node sensing output voltage via resistor divider; sensitive to noise - must be routed away from SW and GND loops. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PSM) | Automatically engages below ~100 mA load to reduce switching frequency and maintain >85% efficiency at light loads - critical for always-on IoT endpoints. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (100 mΩ + inductor DCR); sustains regulation when VIN approaches VOUT - e.g., 1.85 V input for 1.8 V output at 1 A. |
| Integrated Low-RDS(on) FETs | 100 mΩ high-side / 60 mΩ low-side MOSFETs - eliminate external power switches and reduce BOM count while enabling >90% efficiency at 1 A. |
| Internal Soft Start | 800-µs controlled ramp-up prevents inrush current spikes into output capacitors - avoids brownout on shared input rails and extends battery life. |
| Robust Protection Suite | Includes cycle-by-cycle overcurrent limit (3 A), thermal shutdown (150°C), UVLO (2.45 V), and automatic recovery - eliminates need for external fault management circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62568DBVT | 1.5-A rated (vs. 2-A), identical pinout and feature set except lower current limit and slightly higher RDS(on). | Suitable for sub-1.5-A loads where thermal margin or cost reduction is prioritized over headroom. | Select TLV62568DBVT only if peak load remains ≤1.5 A and layout reuse is required - no change to FB divider or inductor needed. |
| TPS62865DRLR | 2-A, 2.5–5.5 V input, but uses 2.0-MHz switching, smaller 1.2-mm × 0.8-mm DSBGA package, and includes PG output. | Better suited for ultra-dense mobile or wearable designs requiring PG signaling and tighter thermal performance (RθJB = 22.5°C/W). | Choose TPS62865DRLR when PG functionality, smaller footprint, or lower thermal resistance is mandatory - requires PCB redesign and updated FB divider. |
Compared with TLV62569DBVT, TLV62568DBVT offers identical integration and layout compatibility at reduced current capacity, while TPS62865DRLR trades SOT23-5 simplicity for advanced features and miniaturization - making TLV62569DBVT optimal for cost-sensitive, thermally moderate 2-A POL applications.

FAQ
What is the maximum output current capability of the TLV62569DBVT?
The TLV62569DBVT delivers up to 2 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 5 V, VOUT = 1.8 V). Its 3-A typical overcurrent limit provides short-term surge tolerance, but sustained operation above 2 A requires thermal derating based on PCB copper area and ambient temperature - verified per datasheet Figure 10 and thermal metrics (RθJA = 188.2°C/W).
Does the TLV62569DBVT include a power-good (PG) output?
No, the TLV62569DBVT does not include a power-good output. The PG pin is only present on TLV62569P variants (e.g., TLV62569PDDC, TLV62569PDRL). The TLV62569DBVT is a 5-pin SOT23 device with EN, GND, SW, VIN, and FB pins - confirmed by Pin Configuration Table on page 3 of SLVSDG1C and Device Comparison table showing "–" for PG marking in TLV62569DBV row.
What is the recommended inductor value for a 1.8-V/2-A TLV62569DBVT design?
Texas Instruments recommends a 2.2-µH shielded power inductor (e.g., Coilcraft XAL4020-222ME) for 1.8-V/2-A operation with 5-V input. This value balances ripple current (≈0.4 A peak-to-peak), size, saturation margin (≥2.6 A ISAT), and efficiency - validated in the Typical Application schematic (Figure 5) and Output Filter Design section (Table 4, row "1.8 ≤ VOUT") of the TLV62569DBVT datasheet.
Can the TLV62569DBVT start up into a pre-biased output capacitor?
Yes, the TLV62569DBVT supports pre-biased startup: when enabled, it senses the existing output voltage and ramps the SW node to bring VOUT smoothly to the regulated setpoint without forcing reverse current into the output cap. This behavior is explicitly documented in Section 7.3.3 (Soft Startup) and confirmed in Figure 16 (Startup with Load) of the SLVSDG1C datasheet.
How does Power Save Mode affect output voltage accuracy in the TLV62569DBVT?
In Power Save Mode, the TLV62569DBVT reduces switching frequency and may allow slight output voltage rise (typically <2% above nominal) due to discontinuous conduction mode. This effect is minimized by increasing output capacitance - TI recommends ≥10 µF ceramic output capacitance (e.g., two 10-µF X7R 0805 caps) to maintain <±1% regulation across 0.1–2 A load range, as shown in Figure 10 (Load Regulation) and detailed in Section 7.3.1.
