Overview

The TLV62569DBVR is a high-efficiency synchronous step-down buck converter designed for compact power solutions. It operates from an input voltage range of 2.5V to 5.5V and provides a regulated output current of up to 2A. With a 1.5MHz switching frequency, the device allows for the use of small external inductors and capacitors.

Why Choose This Part

This regulator features up to 95% efficiency and includes a Power Save Mode to maintain high efficiency during light load operations. Its 100% duty cycle capability allows for very low dropout operation when the input voltage approaches the output voltage. The integrated Power Good output simplifies power sequencing without requiring additional external monitoring components.

Applications

Point-of-Load Regulation
Stepping down 3.3V or 5V rails to lower core voltages for microprocessors and FPGAs.
Battery-Powered Devices
Providing efficient power conversion in Li-ion applications where the 0.1 uA shutdown current extends battery life.
Network Systems
Powering optical modules and networking interface cards requiring a stable 2A supply in a SOT-23 package.

Getting Started

To evaluate this part, use the TLV62569EVM-789 evaluation module which provides a pre-configured layout for testing load transients and efficiency. When designing a custom PCB, place the input capacitor as close as possible to the VIN and GND pins to minimize parasitic inductance. Use the TI WEBENCH Power Designer tool to calculate optimal values for the feedback resistor network and output filter.
