BD9P235EFV-C
Nano Pulse Control™, 3.5V～40V輸入, 2A 3.3V輸出, 車電一次側DC/DC轉換器
BD9P235EFV-C
Nano Pulse Control™, 3.5V～40V輸入, 2A 3.3V輸出, 車電一次側DC/DC轉換器
BD9P系列是兼顧高速回應和高效率的42V耐壓車電一次側DC/DC轉換器IC。其特點是透過Nano Pulse Control™實現的穩定且較大的降壓比、透過擴頻功能實現的低EMI（低雜訊）、在電池剛啟動時也能穩定供電的高速回應性能，有助於降低系統功耗和降低BOM成本。
包括ADAS的感測器、相機、雷達，以及車電資訊娛樂、儀錶板、 BCM（車身控制模組）在內，適用於汽車中要求小型化、高效率化、高可靠性的應用。
