代理 CJ9220T5 长晶1.5A同步升压转换器

INTRODUCTION

The CJ9220 is a high-efficiency, DC to DC step-down switching regulator, capable of delivering up to 2A of output current. The input and output range of CJ9220 is from 2.7V to 5.5V and 0.6V to VIN, making it suitable for low voltage power conversion. Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies. Other external components, such as ceramic input and output caps, can also be small due to higher switching frequency,while maintaining exceptional low noise output voltages. Internal soft-start control circui reduces inrush current.
