LT3484EDCB-1#TRPBF - Step-Up DC/DC Converter

The LT3484EDCB-1#TRPBF is a compact, high-efficiency, fixed frequency step-up DC/DC converter from Linear Technology, designed to provide a reliable power solution for applications requiring voltage boost functionality. This component is particularly suitable for battery-powered equipment, as it can operate with an input voltage as low as 2.7V, making it ideal for single-cell Li-Ion, or multi-cell alkaline/NiMH applications.

One of the key features of the LT3484EDCB-1#TRPBF is its internal 2A, 36V switch, which allows it to power a wide range of loads. The device is capable of generating an adjustable output voltage up to 34V, providing flexibility for various design requirements. Additionally, the LT3484EDCB-1#TRPBF offers a quiescent current of only 300uA, which enhances battery life by reducing standby power consumption.

The converter utilizes a constant frequency, current mode PWM architecture that ensures stable operation over a wide range of supply and output voltages. A high switching frequency of 1.2MHz allows the use of small, low-cost capacitors and inductors, minimizing the overall footprint of the power supply on the circuit board.

Protection features are embedded within the LT3484EDCB-1#TRPBF to safeguard the device and the load. These include a soft-start function to limit inrush current during startup, thermal shutdown, and a current limit to prevent damage from overcurrent conditions. The device also offers a shutdown pin, enabling the user to turn off the converter, reducing the input supply current to less than 1uA during shutdown mode.

Available in a low-profile (2mm) 6-pin DFN package, the LT3484EDCB-1#TRPBF is designed to be a space-saving solution that meets the needs of space-constrained applications. Its small size, combined with its robust feature set, makes it an excellent choice for portable devices, display backlighting, and other applications where efficient power conversion is crucial.

Overall, the LT3484EDCB-1#TRPBF from Linear Technology is a versatile and efficient solution for step-up voltage conversion, offering designers a combination of performance, reliability, and compactness.
