PWM Comtroller
Electrical Characteristics
Electrical characteristics are guaranteed over the full junction temperature range (0-105°). Ambient temperature must be derated
based upon power dissipation and package thermal characteristics. The conditions are: VCC= 15 V, BOK = 3 V, ON = 3 V, RT=
680
, CT= 10 nF, and CWBL= 2.2 nF ,unless otherwise specified. To override UVLO, VCCshould be raised above UVLOHIGH
prior to test.
