Current Mode Controller
Electrical Characteristics
Electrical characteristics are guaranteed over full junction temperature range (0 to 105C). Ambient temperature must be derated
based on power dissipation and package thermal characteristics. The conditions are: V
CC
= 15 V, R
T
= 10 k, and C
T
= 3.3 nF, unless
otherwise stated. To override UVLO, V
CC
should be raised above 17 V prior to test.
