AS2214
Primary Side PWM Controller
Electrical Characteristics (cont’d)
Electrical Characteristics are guaranteed over full junction temperature range (0 to 105° C). Ambient temperature must be derated
based on power dissipation and package thermal characteristics. Unless otherwise specified, the conditions of test are VCC = 15 V;
BOK = 3 V; OV = 0V; RT = 680 Ω; CT = 10 nF. To override UVLO, VCC should be raised above 18 V prior to test.
