Electrical Characteristics Limits in standard type are for T_J= 25°C only; limits in boldface type apply over the

junction temperature (T_J) range of -40°C to +125°C. Minimum and Maximum limits are guaranteed through test, design, or statistical

correlation. Typical values represent the most likely parametric norm at T_J= 25°C, and are provided for reference purposes only.

Unless otherwise stated the following conditions apply: VIN = 48V.
