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.
