| FAN5330 High Serial LED Driver with 30V Integrated Switch August 2005 FAN5330 High Serial LED Driver with 30V Integrated Switch • 1.5MHz Switching Frequency • Low Noise • Adjustable Output Voltage • 0.7W Output Power Capability • Low Shutdown Current <1µA • Cycle-by-Cycle Current Limit • Low Feedback Voltage 110mV • Over-Voltage Protection • Fixed-Frequency PWM Operation • Internal Compensation • Thermal Shutdown • 5-Lead SOT23 Package • Cell Phones • PDAs • Handheld Equipment • Display Bias • LED Bias The FAN5330 is an LED driver that features 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. 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 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. The FAN5330 is available in a 5-lead SOT23 package.
