ELECTRICAL CHARACTERISTICS (continued)

Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the appropriate operating junction

temperature (TJ) range of -40°C to +125°C (LM5050MK-1, LM5050Q1MK-1) or -40°C to +150°C (LM5050Q0MK-1). Minimum

and Maximum limits are specified 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 = 12.0V, VVS = VIN, VOUT = VIN, VOFF = 0.0V, CGATE= 47 nF, and TJ = 25°C.
