SNVS691H – JANUARY 2011 – REVISED OCTOBER 2015

Electrical Characteristics (continued)

Limits are for TJ = 25°C unless otherwise specified. 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
