Description
The FAN5333A/FAN5333B is a general purpose 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 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. Normal or shutdown mode can be selected
by a logic level shutdown circuitry.
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 FAN5333A/FAN5333B is available in
a 5-lead SOT23 package.
