Secondary Side Housekeeping Circuit

ASTEC Semiconductor

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 = 12 V;

+3.3 V = 3.3 V; +5 V = 5V; +12 V = 12 V; –12 V = –12 V; – 5 V = – 5 V.
