6.5 Electrical Characteristics

Unless otherwise stated the following conditions apply: VIN = 14 V, EN = 2.00 V, UVLO = 2.00 V, OVP = 1.50 V, and TJ = 25°C. Limits in standard type are for TJ = 25°C except where noted. 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.

(1) The GATE pin voltage is typically 12 V above the VIN pin when the LM5060 is enabled. Therefore, the Absolute Maximum Rating for VIN (75 V) applies only when the LM5060 is disabled, or for a momentary surge to that voltage since the Absolute Maximum Rating for the GATE pin is also 75 V.
