省スペースと省エネを両立した車載用セカンダリ電源の決定版
Space-saving Energy-Efficient Secondary Power Supplies for Automotive Systems
同期整流降圧DC/DCスイッチングコンバータ
Synchronous Buck DC/DC Switching Converters
BD905xx-C Series
Features
●位相補償、帰還抵抗、ソフトスタート内蔵で最小3つの外付け
部品でアプリケーションを構成可能、外付け部品を大幅削減
（出力電圧固定タイプ）
Highly integrated design with built-in phase compensation,
feedback resistor, and soft start function reduces the number of
external components required to only 3 (fixed output type)
●外付け抵抗で出力電圧、発振周波数、位相補償を設定可能
（出力電圧可変タイプ）
HTSOP-J8
Output voltage, oscillation frequency, and phase compensation
adjustable via external resistor (variable output voltage type)
●-40℃から+125℃動作、AEC-Q100対応
Wide operating temperature range (-40°C to +125°C), AEC-Q100 qualified
