Electrical Characteristics (Continued)
(Ta=25
°C unless otherwise specified)
Note:
1. These parameters is the current flowing in the Control IC.
2. These parameters, although guaranteed, are tested only in EDS (wafer test) process.
3. These parameters indicate Inductor Current.
4. These parameters, although guaranteed at the design, are not tested in mass production.
