The LTC3490EDD#TRPBF is a high-efficiency, monolithic boost converter from Linear Technology, designed to deliver a continuous output current of up to 350mA. This compact and versatile power solution is encapsulated in a small 8-lead DFN package, making it an ideal choice for space-constrained applications.
With an input voltage range of 2.5V to 10V, the LTC3490EDD#TRPBF can operate from a single lithium-ion cell, multiple alkaline/NiMH cells, or other standard power supplies, providing a versatile solution for portable devices. The output voltage is adjustable up to 34V, which can be set via an external resistor divider, catering to a wide range of applications that require different voltage levels.
The device features a high switching frequency of 1.2MHz, which allows the use of small, low-cost capacitors and inductors, further reducing the overall solution footprint. Additionally, the LTC3490EDD#TRPBF incorporates internal soft-start functionality to limit inrush current during startup, enhancing system reliability.
Another notable characteristic of this boost converter is its high efficiency, which can reach up to 88%. This is achieved through the use of low VCESAT bipolar transistors and an adaptive current mode PWM control scheme. The result is reduced power loss and improved battery life for portable applications.
The LTC3490EDD#TRPBF also includes several protective features to safeguard the device under abnormal conditions. These include overvoltage protection, thermal shutdown, and a current limit function. The overvoltage protection circuitry disables the power switch when the output voltage exceeds the programmed value, preventing damage to the load or the converter itself.
Supplied in tape and reel packaging, the LTC3490EDD#TRPBF is specifically designed for automated manufacturing processes, ensuring high production efficiency and reliability. This product is suitable for a range of applications, including OLED displays, GPS devices, portable lighting, and small-scale power supplies.
