Description

The FAN5333BSX is a high efficiency, high current serial LED Driver with 30V integrated switch. The FAN5333B is a general-purpose LED driver that features fixed-frequency mode operation and an integrated FET switch. This device is high output power makes it suitable to drive flash LEDs in serial connections. This device is designed to operate at high switching frequencies 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 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 current limit circuit keeps the peak current of the switch below a typical value of 1.5A.
