Lad711p Rev 10 Schematic Top !new! Jun 2026
Measure pin 11 ( VIN ), pin 12 ( ENLDO ), pin 14 ( LDO5 ), and pin 15 ( LDO3 ). If LDO lines read 0V or are heavily dragged down to short-circuit resistance scales, the chip or its matching SMD capacitors have failed. Symptom B: No Display, Fan Spins to Maximum Speed
: Right after the isolation MOSFETs sits the primary current sense resistor ( PRxxx ). If this resistor or its sensing lines are damaged, the entire board will remain completely dead, blocking power to all downstream sub-regulators. 2.
