CJ9482E8 江苏长晶 单片降压开关稳压器 ESOP8封装

INTRODUCTION

CJ9482 is a monolithic 36V,3.1A step-down switching converter. CJ9482 integrates a 36V 79mΩ high side and a 36V, 62mΩ low side MOSFETs to provide 3.1A continnuous load current over a 6.5V to 36V wide operating input voltage with 33V input over voltage protection. Peak current mode control provides fast transient responses and cycle-bycycle current limiting. Programmable softstart prevents inrush current at power.
