3.9~30V 입력, 2ch 동기정류 강압 컨트롤러 - BD9015KV-M

BD9015KV-M은 넓은 입력 범위에서 사용 가능한 2출력 동기정류 스위칭 컨트롤러입니다. 동기정류 방식으로 고효율을 실현하여, 모든 전자기기의 저소비전력화에 기여할 수 있습니다. 각 출력에 EN 단자, 소프트 스타트 기능, POWER GOOD 기능을 구비하여, turn-on / turn-off의 독립 제어가 가능합니다. 또한, PLL 회로를 내장하여 250kHz~600kHz의 외부 CLK로 동기 가능합니다.

특징 :
    • N channel MOSFET direct drive
    • Synchronous rectification for increased efficiency
    • Acceptable Low ESR ceramic capacitor at output
    • Integrated PLL circuit for external synchronization; 250kHz to 600kHz
    • Current mode control
    • High side MOSFET current sensing
    • Pre-bias functionality
    • Independent ON/OFF control for all channels
    • At Max Duty the oscillation frequency is slowed down to 1/5, reducing the input/output voltage difference.
    • Low voltage and over voltage detection circuit at all outputs
      When the over voltage is detected, the L-side FET is OFF (BD9015KV-M). The L-side FET is ON (BD9016KV-M).
      Low side FET is ON (BD9016KV-M)
    • Power good indicator pin (PGOOD)
    • Integrated overcurrent protection with self recovery.
