4.2 Optional Components

Table 4-1 shows a list and function of optional components placed in the schematic

Table 4-1 Optional Components
Component Function

R47 / C34

R48 / C35

R50 / C36

 Filter for digital signals; can be added in a noisy setup. If not used, add 0 Ohm for the resistors.
J12 / R22 / R23 / R51 /R52 I2C interface - not available for the LM5177. Pins are used as logic level output of HO1 and HO2, see data sheet.
R18 / R17 / C33 Footprint for filter circuit on IMONOUT, see data sheet for component selection to configure that function.
D3 / D4 Placeholder for external BOOT diodes.
R42 / R43 / C30 Input filter for ISNS input.
Reverse CV Regulation Section Can add CV control in reverse CC Mode.
