BD93291EFJ
2ch 同期整流降圧コンバータ
The BD93291EFJ is a dual synchronous buck converter. It integrates wide input voltage range (8.0V to 26V) synchronous buck converter and low input voltage (Vout1 : 5.0V) synchronous buck converter. The IC also incorporates a new technology called H3RegTM, a Rohm proprietary control method which facilitates ultra-high transient response against changes in load. SLLM (Simple Light Load Mode) technology is also integrated to improve efficiency when powering lighter loads. For protection and ease of use, the IC also incorporates soft start. Space-saving and high efficient switching regulator can be achieved due to built-in N-MOSFET power transistor in HTSOP-J8 package.
