ROHM Product Detail

BD9G201UEFJ-LB
1ch 降压型开关稳压器

本IC是内置高边FET的二极管整流式降压型开关稳压器,支持在4.5V~42V的电源电压范围内工作。该产品通过电流模式控制实现了高速负载响应和简单的相位补偿设置。例如在小型二次侧电源应用中,可以将12V、24V等电源降压后输出3.3V、5V等电压。另外,该产品还具有与外部CLK同步的功能,可以进行噪声管理。

本IC是为提高生产效率而对本系列产品中的BD9G201EFJ-LB变更生产线后形成的型号,在新项目选型时,建议选择该型号,在技术规格书中的保证特性并没有差异。此外,由于文档和设计模型等也没有差异,因此除非另有说明,ROHM将公开BD9G201EFJ-LBE2的数据。

Reference Design / Application Evaluation Kit

 
    • Evaluation Board - BD9G201EFJ-EVK-001
    • This EVK is using BD9G201EFJ-M instead of BD9G201UEFJ-M, BD9G201UEFJ-LB, or BD9G201EFJ-LB. This EVK has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G201EFJ-M. While the BD9G201EFJ-M accepts a power supply input range of 4.5V to 42V, and generates output voltages from 1V to VCC, this EVK is setup for the input voltage range of 10V to 42V and a fixed output of 5V can be produced.
