**LT8335EDDB#TRPBF: A High-Performance Boost/SEPIC/Inverting Converter with Wide Input Range and Programmable Frequency**

The **LT8335EDDB#TRPBF** from Analog Devices is a versatile and highly efficient monolithic switching regulator that excels in a variety of DC/DC converter topologies, including **boost, SEPIC, and inverting configurations**. Its primary strength lies in its ability to deliver robust performance across a broad spectrum of industrial, automotive, and telecommunications applications where space, efficiency, and flexibility are paramount.

A standout feature of this IC is its exceptionally **wide input voltage range of 3V to 40V**. This allows it to seamlessly handle power sources ranging from a single lithium-ion battery to unregulated 24V industrial rails and even transient-heavy automotive environments, all without missing a beat. The device can generate output voltages up to 60V, making it suitable for driving high-voltage amplifiers, bias supplies, and a multitude of industrial sensors.

Furthermore, the LT8335 offers a **programmable switching frequency from 200kHz to 2MHz**. This programmability provides system designers with significant flexibility. They can optimize efficiency by selecting a lower frequency or minimize the solution size by using a higher frequency with smaller external inductors and capacitors. The high switching frequency also enables the use of low-profile components, which is critical for modern, space-constrained PCB designs. The device's **1.4A, 40V internal switch** ensures low power loss and delivers high efficiency across a wide load range.

The converter incorporates advanced design features such as frequency foldback for limiting inductor current during start-up and a soft-start function to prevent inrush currents. Its **low quiescent current of just 9µA** in shutdown mode makes it an excellent choice for battery-operated systems that demand long operational life. The LT8335 is available in a compact 8-lead DFN package, offering a high-performance solution in a minimal footprint.

ICGOOODFIND: The LT8335EDDB#TRPBF stands out as an exceptionally flexible and resilient power conversion solution, masterfully combining a wide operating range, user-configurable frequency, and high integration to address complex power supply design challenges across diverse markets.
