Overview

The TLV61046ADBVR is a highly integrated boost converter designed for applications requiring output voltages up to 28V from a low-voltage input. It features an integrated power diode and an isolation switch that provides a true load disconnect during shutdown, which is critical for preventing battery drain and protecting sensitive loads.

Why Choose This Part

This device eliminates the need for an external Schottky diode and an external load switch, significantly reducing PCB area. It operates at a 1.05MHz switching frequency to allow for small inductors while maintaining a low 0.1uA shutdown current for extended battery life.

Applications

PMOLED Power Supply
Provides the high-side voltage rail required for passive-matrix OLED displays in wearable devices.
LCD Bias Rails
Generates the necessary bias voltages for small to medium-sized liquid crystal displays.
Medical Sensor Probes
Powers transducers or sensors that require a higher operating voltage than the standard 3.3V battery rail.

Getting Started

Designers should prioritize placing the input capacitor and output capacitor close to the IC pins to minimize high-frequency switching loops. For rapid evaluation, Texas Instruments offers the TLV61046AEVM-833 evaluation module which demonstrates the typical 12V output configuration.

Also Consider

TPS61040DBVR TITexas Instruments - Offers a higher maximum output voltage of 28V but requires an external diode and does not provide integrated load isolation.
