BD50GA5MEFJ-M
針對車用裝置的0.5A可變輸出／固定輸出LDO穩壓器
BDxxGA5MEFJ-M系列是可提供0.5A輸出電流的穩壓器。輸出精度為±1%。有可使用外接電阻在1.5V～13.0V範圍內任意設置輸出電壓的可變型以及1.5V/1.8V/2.5V/3.0V/3.3V/5V/6V/7V/8V/9V/10V/12V固定輸出型兩種。封裝組件採用散熱性優良的HTSOP-J8。本機型內建用於防止因輸出短路等發生IC破壞的過電流保護電路、關斷時使電路電流為0µA的ON/OFF開關、以及防止因過負載狀態等使IC發生熱破壞的溫度保護電路。
另外，採用了陶瓷電容，有助於整機的小型化和長壽化。

- 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.
