The LT1613CS5#PBF is a compact, high efficiency, step-up DC/DC converter from Linear Technology, an Analog Devices company. Designed for small form factor applications, this converter is housed in a 5-lead ThinSOT package, making it ideal for space-constrained designs.

With an input voltage range of 1.2V to 15V, the LT1613 is versatile enough to be powered from a single cell lithium-ion battery or various other power sources. It can deliver a fixed output voltage of 5V or an adjustable output up to 34V, with output currents up to 600mA (depending on input/output voltages and external components).

This converter utilizes a current mode, fixed frequency architecture, providing a stable operation over a wide range of supply and output voltages. The switching frequency of 1.2MHz allows for the use of small, low-cost capacitors and inductors, reducing the overall footprint of the power supply circuit.

The LT1613CS5#PBF features include a low quiescent current of 2.5µA in shutdown, which extends battery life in portable applications. It also incorporates internal soft-start, a low-battery detector, and a current limit to protect the device and the load during over-current conditions.

Applications for the LT1613CS5#PBF are diverse, ranging from personal digital assistants (PDAs) and cellular phones to handheld medical and industrial devices. Its ability to boost low voltages to higher levels makes it suitable for LED drivers and small OLED panels as well.

With its high frequency operation and ability to maintain a low noise output, the LT1613CS5#PBF is also well-suited for RF power supplies and other sensitive applications where a minimal noise footprint is critical.

Linear Technology's commitment to high-quality and reliable products ensures that the LT1613CS5#PBF step-up converter is a robust choice for designers looking to optimize power efficiency in their next project.
