TPS61040QDBVRQ1 TI DC-DC Boost Converter | SOT-23-5 | 2.2-5.5V Input, 28V Output

Product Overview

The TPS61040QDBVRQ1 from Texas Instruments is a high-frequency, high-efficiency boost converter in a compact SOT-23-5 package. It is designed to provide a regulated output voltage up to 28V from a low-voltage input supply ranging from 2.2V to 5.5V. This device is ideal for applications requiring a small solution size and low quiescent current, such as portable equipment, battery-powered systems, and automotive infotainment. The TPS61040QDBVRQ1 operates at a fixed switching frequency of 1.2 MHz, allowing the use of small external components. It features a built-in 0.5A, 28V power switch, making it suitable for generating bias voltages for LCD displays, OLED panels, and other high-voltage rails.
