Description and Introduction

VFM Step-up DC/DC Converter # RT9261-40CX: A High-Efficiency Step-Down DC-DC Converter for Modern Applications  

The **RT9261-40CX** is a high-performance, synchronous step-down DC-DC converter designed to deliver efficient power conversion for a wide range of electronic applications. With its compact footprint and advanced features, this component is an excellent choice for designers seeking reliable voltage regulation in space-constrained environments.  

Engineered for efficiency, the RT9261-40CX operates at a fixed switching frequency of **1.5MHz**, enabling the use of smaller external components while maintaining stable performance. Its synchronous rectification architecture minimizes power loss, achieving **up to 95% efficiency**, making it ideal for battery-powered devices and energy-sensitive systems.  

The device supports an input voltage range of **2.5V to 5.5V**, with a fixed **0.8V to 3.3V adjustable output**, ensuring compatibility with low-voltage logic circuits, microcontrollers, and portable electronics. The built-in **soft-start function** prevents inrush current, enhancing system reliability during startup.  

Additional features include **over-current protection (OCP) and thermal shutdown**, safeguarding the converter and connected components under fault conditions. The RT9261-40CX is available in a **WDFN-10L 3x3 package**, offering excellent thermal dissipation and board space optimization.  

Whether used in IoT devices, wearables, or embedded systems, the RT9261-40CX provides a robust and efficient power solution, simplifying design challenges while maintaining high performance. Its combination of low power consumption, compact form factor, and integrated protection mechanisms makes it a versatile choice for modern electronic applications.  

For engineers prioritizing efficiency and reliability, the RT9261-40CX stands out as a dependable DC-DC converter solution.
