Electrical Characteristics (Continued)
(Ta=25°C unless otherwise specified)
Notes:
1. These parameters are the current flowing in the Control IC.
2. These parameters, although guaranteed at the design, are not 100% tested in production.
3. These parameters, although guaranteed, are tested in EDS(wafer test) process.
4. These parameters indicate Inductor current.
