Core Features & Advantages

The TLV62569PDDCT delivers 2A synchronous buck conversion with up to 95% efficiency in an ultra-compact SOT-23-THIN package, featuring integrated power MOSFETs and automatic power-save mode for light-load efficiency.

  • Primary Function: 2A synchronous step-down DC-DC converter with adjustable output from 0.6V to VIN, optimized for general-purpose POL power supply from 2.5V–5.5V input rails.
  • Advantages:
    • Integrated 100mΩ/60mΩ synchronous MOSFETs — eliminates external Schottky diode and high-side switch, reducing BOM count and solution footprint to under 25mm².
    • Automatic Power Save Mode (PSM) — seamlessly transitions from PWM to PFM at light loads, maintaining >80% efficiency down to 1mA output current.
    • 100% duty cycle operation — enables near-zero dropout when VIN approaches VOUT, extending usable battery range in single-cell Li-ion applications.

Typical Application Scenarios

  • Industry: Consumer / Industrial / Networking
  • Equipment: Set-top boxes, wireless routers, network cameras, hard disk drives, portable devices
  • Use Cases:
    • General-purpose 3.3V or 1.8V POL supply from 5V or 3.6V rail in space-constrained networking equipment.
    • Single-cell Li-ion (3.0V–4.2V) to 1.8V/1.2V buck conversion in portable instruments with PSM extending battery life.
    • Post-regulation after a front-end DC-DC or USB power source, providing clean 1.2V core voltage for FPGAs/SoCs.
