BD50GA5MEFJ-M
面向车载设备的0.5A可变输出／固定输出LDO稳压器
BDxxGA5MEFJ-M系列是可提供0.5A输出电流的稳压器。输出精度为±1%。有可使用外接电阻在1.5V～13.0V范围内任意设置输出电压的可变型以及1.5V/1.8V/2.5V/3.0V/3.3V/5V/6V/7V/8V/9V/10V/12V固定输出型两种。封装组件采用散热性优良的HTSOP-J8。本机型内置用于防止因输出短路等发生IC破坏的过电流保护电路、关断时使电路电流为0µA的ON/OFF开关、以及防止因过负荷状态等使IC发生热破坏的温度保护电路。
另外，采用了陶瓷电容器，有助于整机的小型化和长寿化。

- Application EVK - APEVK66001
- Industrial 3.6kW Totem Pole PFC Application EVK
Various applications are equipped with AC/DC functions, and the Totem Pole PFC topology is the standard circuit.The TPPFCSIC-EVK-301 implements a single-phase AC/DC conversion stage in Totem Pole PFC topology. Key components are ROHM Gen.4 SiC MOSFETs (SCT4045DR) as the main high-frequency switching elements, as well as the BM61S41 single-channel isolated gate driver IC. In addition, SJ MOSFETs and auxiliary power supply, among other components from ROHM, were utilized to create a high-performance AC/DC circuit for single-phase operation.TPPFCSIC-EVK-301 reaches up to 98.5％ efficiency at 230Vac.If this Totem Pole PFC reference design is coupled with a secondary stage of comparable efficiency, it becomes possible to achieve the 80+ Titanium target efficiency of power supply products. Moreover, this contributes to enhancing the Annual Performance Factor (APF) of air conditioners.
This reference design consists of two boards. Each is shown below.
