DCDC_5 controls its own ramp rate. # # # Board_Location # Ref Part_Number Symbol Geometry X Y Properties #----- ----------- ------ ------------------ -------------- ---------- # DCDC5 POL_PDT012A SY_JUNK GE_PDT012 0.00 0.00 1 180 ($G,"$O,$V") (COMPONENT_TYPE,"Array_Grp") # # The loop compensation RTUNE and CTUNE RC components # R1201 Res_180_Ohm_0805 SY_JUNK res_0805 5.60 7.00 2 180 C1201 Cap_10_nFd_0805 SY_JUNK cap_0805_1sb 1.20 7.00 2 180 # # The output voltage set RTRIM resistor # R1202 Res_20k_Ohm_0805 SY_JUNK res_0805 1.20 2.10 2 180 # # The Address Set resistors: Adrs_1 is R1204 Adrs_0 is R1203 set to 0o53 # R1204 Res_84.5k_Ohm_0603 SY_JUNK res_0603 1.00 -2.50 2 0 R1203 Res_36.5k_Ohm_0603 SY_JUNK res_0603_1sb 1.00 -4.50 2 0 # # Now the Ramp Sequence RC scale and filter components: # # Recall that DCDC_5 does not use the analog Ramp Sequence # signal.
