7. VEN shown only for NCP45520−H, NCP45521−H (EN Active−High) unless otherwise specified.
8. Average current from VIN to VOUT with MOSFET turned off.
9. Average current from VCC to GND with MOSFET turned off.
10.Average current from VCC to GND after charge up time of MOSFET.
11. PG is an open-drain output that is pulled low when the MOSFET is disabled.
12.PG is an open-drain output that is not driven when the gate of the MOSFET is fully charged, requires an external pull up resistor ≥ 1 kW to
an external voltage source, VTERM.
13.See Applications Information section for details on how to adjust the slew rate.
14.Operation above TJ = 125°C is not guaranteed.
