WPMDH1100601 / 171010601
MagI3C Power Module
VDRM – Variable Step Down Regulator Module
ELECTRICAL SPECIFICATIONS
MIN and MAX limits are valid for the recommended junction temperature range of -40°C to 125°C. Typical values represents
statistically the utmost probability at following conditions: VIN = 24V, VOUT = 3.3V, TA = 25°C, unless otherwise specified.
