7.1 Recommended Schematic Overview

There are several critical components that must be used in conjunction with this power block device. Figure 32 shows a portion of a schematic with the critical components needed for proper operation.

  • C22: Bypass capacitor for VIN to help with ringing reduction
  • C20: Bootstrap capacitor
  • C21: Bypass capacitor for VDD
  • C7-C14: Bypass capacitors for VIN (minimum of 40 µF)
  • C15: Electrolytic capacitor for VIN
  • R14, R16: Place holder for gate resistor (optional)
  • R15: Place holder for bootstrap resistor (optional)
  • R17, C16: Place holder for snubber (optional)
