Description and Introduction

Tiny Package, High Performance, Constant Current Switching Regulator for White LED # RT9284B-20PJ6: A High-Performance Step-Up DC-DC Converter for Modern Electronics  

The **RT9284B-20PJ6** is a highly efficient, synchronous step-up DC-DC converter designed to meet the demanding power requirements of today’s portable and compact electronic devices. With an input voltage range of **0.8V to 5.5V** and an adjustable output voltage up to **5.5V**, this component is ideal for applications such as **smartphones, wearables, IoT devices, and battery-powered systems**.  

One of the standout features of the RT9284B-20PJ6 is its **integrated synchronous rectification**, which significantly improves efficiency—up to **95%**—while minimizing power loss. This makes it an excellent choice for energy-sensitive designs where extended battery life is crucial. Additionally, the converter operates at a **1.2MHz switching frequency**, allowing for the use of small external components, thereby reducing PCB footprint and overall system cost.  

The device incorporates **low quiescent current (IQ) of just 20µA**, ensuring minimal power consumption during standby or light-load conditions. Its **automatic pulse-frequency modulation (PFM) mode** further enhances efficiency across varying load conditions, making it adaptable to dynamic power demands.  

For enhanced reliability, the RT9284B-20PJ6 includes built-in protection features such as **over-current protection (OCP), thermal shutdown, and soft-start functionality**, safeguarding both the converter and the connected circuitry from potential damage.  

Available in a compact **SOT-23-6 package**, the RT9284B-20PJ6 is designed for space-constrained applications, offering a balance of performance, efficiency, and durability. Whether used in consumer electronics, medical devices, or industrial sensors, this step-up converter delivers consistent, high-quality power conversion with minimal external components.  

Engineers and designers seeking a **reliable, high-efficiency power solution** will find the RT9284B-20PJ6 to be a versatile and robust choice for their next-generation electronic designs.
