长晶 CJ9118B50T5 同步升压转换器 深圳原装现货

INTRODUCTION

The CJ9118 Series is a CMOS PFM-control step-up switching DC/DC converter. This products with a low ripple over a wide range, high efficiency, and high output current. With the CJ9118 Series, a step-up switching DC/DC converter can be configured by using an external coil and capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the SCJ9118 Series ideal for applications such as the power supply unit of portable equipment.
