FAN5333BSX Datasheet

LED Lighting Drivers


The FAN5333A/ FAN5333BSX is a general purpose LED driver that features fixed frequency mode operation and an integrated FET switch. The device&rsquo;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. FAN5333BSX Features &bull; 1.5MHz Switching Frequency&bull; Low Noise&bull; Adjustable Output Voltage&bull; Up to 1.5A Peak Switch Current&bull; 1.5W Output Power Capability&bull; Low Shutdown Current: <1&mu;A&bull; Cycle-by-Cycle Current Limit&bull; Low Feedback Voltage&bull; Over-Voltage Protection&bull; Fixed-Frequency PWM Operation&bull; Internal Compensation&bull; FAN5333A has 110mV Feedback Voltage&bull; FAN5333B has 315mV Feedback Voltage&bull; Thermal Shutdown&bull; 5-Lead SOT23 Package
