功能:
    • 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.
