WPMDH1100xx1S / 173010x42
MagI3C Power Module
FDSM – Fixed Step Down Regulator Module
ELECTRICAL SPECIFICATIONS
MIN and MAX limits are valid for the recommended ambient temperature range of -40°C to 85°C. Typical values represent
statistically the utmost probability at the following conditions: VIN = 24V, VOUT = 3.3V (173010342), VOUT = 5V (173010542),
IOUT = 0.1 to 1A(5) unless otherwise specified.
