BD9G341AEFJ-LB
1ch降壓開關穩壓器
本產品專為工具機市場設計、並保證可長期供貨的Rank產品。BD9G341AEFJ-LB為高電壓76V輸入對應並內建功率MOSFET的降壓1ch開關穩壓器。耐壓80V額定3.5A、內建導通電阻150mΩ功率MOSFET。 此外可依電流模式控制方式、達成高速暫態響應和簡單的相位補償設定。頻率在50kHz ～ 750kHz之間可變動、並內建低電壓誤運作防止電路、過電流保護電路等保護功能。此外透過高精度的EN引腳門限可低電壓鎖定、或是外接遲滯電阻進行設定。

- Evaluation Board - BD9G341AEFJ-EVK-101
This EVK is using not BD9G341AEFJ-LB, but BD9G341AEFJ. This evaluation board has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G341AEFJ. While the BD9G341AEFJ accepts a power supply input range of 12V to 76V, and generates output voltages from 1V to Vcc, this evaluation board is setup for the same input voltage range and a fixed output of 5V can be produced.
