FAN5331SX Datasheet

High Efficiency Serial LED Driver and OLED Supply with 20V Integrated Switc


The FAN5331SX is a general purpose, fixed-frequency boost con- verter designed to operate at high switching frequencies in order to minimize switching noise measured at the battery ter- minal of hand-held communications equipment. Quiescent cur- rent in normal mode of operation as well as in shutdown mode is designed to be minimal in order to extend battery life. Normal mode of operation or shutdown mode can be selected by a logic level shutdown circuitry. FAN5331SX Features &bull; 1.6MHz Switching Frequency&bull; Low Noise&bull; Low RDS(ON); 0.5Q&bull; Adjustable Output Voltage&bull; 1A Peak Switch Current&bull; 1W Output Power Capability&bull; Low Shutdown Current: <1UA&bull; Cycle-by-Cycle Current Limit&bull; Over-Voltage Protection&bull; Fixed-Frequency PWM Operation&bull; Internal Compensation&bull; 5-lead SOT-23 Package FAN5331SX Applications &bull; Cell Phones&bull; PDAs&bull; Handheld Equipment&bull; Display Bias&bull; LED Bias
