Description and Introduction

TinyBuck?- 4A, 24V Single-Input Integrated Synchronous Buck Regulator **Introduction to the FAN21SV04 by Fairchild Semiconductor**  

The **FAN21SV04** is a high-performance, synchronous buck regulator from Fairchild Semiconductor, designed to deliver efficient power conversion in compact applications. This integrated circuit (IC) combines a PWM controller and MOSFETs in a single package, optimizing space and reducing external component count.  

Operating within an input voltage range of **4.5V to 21V**, the FAN21SV04 provides a regulated output voltage as low as **0.8V**, making it suitable for a variety of low-power systems, including networking equipment, industrial controls, and consumer electronics. Its **synchronous rectification** architecture enhances efficiency, minimizing power loss and heat generation.  

Key features include **adjustable switching frequency**, **soft-start capability**, and comprehensive protection mechanisms such as overcurrent, overvoltage, and thermal shutdown. The device supports **up to 4A of continuous output current**, ensuring reliable performance under demanding conditions.  

Packaged in a **space-saving 8-pin SOIC**, the FAN21SV04 is ideal for applications where board space is limited. Its robust design and high efficiency make it a dependable choice for engineers seeking a compact, high-performance DC-DC converter solution.  

Fairchild Semiconductor’s FAN21SV04 exemplifies modern power management technology, balancing performance, efficiency, and integration for next-generation electronic systems.
