Key Differentiators

  • Integrated high-voltage startup cell (vs NCP1562)
  • I2C control interface (vs NCP1562)
  • Wide input voltage range (vs NCP1562)

Design Notes

Place the high-voltage startup cell input (HV pin) away from sensitive analog traces to prevent noise coupling. Use a dedicated ground plane for the power stage and keep the gate drive trace short and wide to minimize parasitic inductance.

The SO-16 package has a thermal resistance that requires adequate copper area for heat dissipation. For high-power applications, ensure the PCB has a large ground plane and consider adding thermal vias under the device to improve heat transfer.

Do not exceed the maximum input voltage of 23V. Ensure the I2C lines are properly pulled up and isolated from high-voltage areas. The compensation pin (COMP) should be connected to a suitable RC network as specified in the datasheet to ensure loop stability.
