LT3473EDD#PBF - A Compact Micropower DC/DC Converter

The LT3473EDD#PBF is a versatile and compact micropower step-up DC/DC converter from Linear Technology, designed to meet the needs of a wide range of applications. This device is particularly well-suited for battery-powered systems, where its high efficiency and low quiescent current extend battery life. The LT3473EDD#PBF is housed in a small 10-lead DFN package, making it an excellent choice for space-constrained applications.

One of the standout features of the LT3473EDD#PBF is its integrated Schottky diode, which simplifies the design and reduces external component count. This integration not only saves board space but also enhances overall reliability and efficiency. The device operates from an input voltage range of 1.2V to 15V, allowing it to support a wide variety of power sources, from single-cell Li-Ion batteries to multi-cell alkaline/NiMH batteries or even regulated 5V and 12V power supplies.

The LT3473EDD#PBF offers adjustable switching frequencies up to 2MHz, which enables the use of small, low-cost capacitors and inductors. This high switching frequency also allows for fast transient response, making it ideal for applications that require quick adjustments to varying loads. The device's soft-start feature minimizes inrush current during startup, protecting both the converter and the load from sudden surges in power.

With its internal 36V/1.3A power switch, the LT3473EDD#PBF can deliver output voltages as high as 34V, making it suitable for driving LEDs, OLED displays, and other high-voltage applications. The device features a low-profile (0.75mm) and a small footprint (3mm x 3mm), which combined with its high level of integration, make it an excellent choice for portable and miniaturized electronic devices.

Overall, the LT3473EDD#PBF from Linear Technology is a high-performance, easy-to-use DC/DC converter that offers a compact solution for a variety of applications. Its combination of features, such as integrated Schottky diode, wide input voltage range, high switching frequency, and high output voltage capability, make it a versatile choice for designers looking to optimize power management in their products.
