These parameters are not ensured by production testing. Limits apply over the recommended operating junction temperature range of –40°C to +150°C, unless otherwise noted. 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 = 13.5 V. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN-MIN Minimum input voltage for full functionality at 1.5 A load, after start- up. VOUT = 3.3 V +2/–3% regulation 3.5 V Minimum input voltage for full functionality at maximum rated load 3.5 A after start-up.

(2) This is the time from the rising edge of EN to the time that the soft-start ramp begins. (3) Tw is the wait time between current limit trip and re-start. Tw is nominally 4× the soft-start time. However, provision must be made to make Tw longer to ensure survivability during an output short circuit. 7.7 Timing Characteristics Limits apply over the recommended operating junction temperature range of –40°C to +150°C, unless otherwise 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. Unless otherwise stated the following conditions apply: VIN = 13.5 V.
