8.5 Electrical Characteristics

Limits apply over the recommended operating junction temperature range of -40°C to +150°C, unless otherwise stated. Minimum and Maximum limits are specified 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: V_IN = 13.5 V. VIN1 shorted to VIN2 = V_IN. V_OUT is converter output voltage.

(1) High side current limit is function of duty factor. High side current limit is highest at small duty factor and less at higher duty factors.

(2) Parameter specified by design, statistical analysis and production testing of correlated parameters.
