Description
The FAN5332A is an LED driver that features fixed frequency
mode operation and an integrated FET switch. The device’s
high output power makes it suitable to drive flash LEDs in serial
connections. This device is designed to operate at high switch-
ing 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. Normal or
shutdown mode can be selected by a logic level shutdown cir-
cuitry.
The low ON-resistance of the internal N-channel switch ensures
high efficiency and low power dissipation. A cycle-by-cycle cur-
rent limit circuit keeps the peak current of the switch below a
typical value of 1.5A. The FAN5332A is available in a 5-lead
SOT23 package.
