Electrical Characteristics (continued)

Minimum and Maximum limits are ensured through test, design or statistical correlation. Typical values represent the most

likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following

conditions apply: VIN = 24 V, VOUT = 12 V, RON = 249 kΩ
