... Typical Application 2 ©2005 Fairchild Semiconductor Corporation FAN5330 Rev. 1.0.1 Description The FAN5330 is an LED driver that features fixed frequency mode operation and an integrated FET switch. This device is designed to operate at high switching frequencies in order to minimize switching noise measured at the battery terminal of hand-held communications equipment. Quiescent current in both normal and shutdown mode is designed to be minimal in order to extend battery life ...
