Overview
ACT6310 Datasheet Rev 0, 1/2005 PRELIMINARY ACT6310 White LED Step-Up Converter FEATURES Inherently Matched LED Current Pin Compatible with ‘1937 with Higher Efficiency (Up to 86%) 30V High Voltage Switch 1.
2MHz Switching Frequency Uses 0.
22µF Output Capacitor SOT23-5 Package APPLICATIONS Cellular Phones Digital Cameras PDAs, Handheld Computers MP3 Players GPS GENERAL DESCRIPTION The ACT6310 step-up DC/DC converter drives white LEDs with a programmable constant current.
The device is capable of driving two, three or four white LEDs in series from a Lithium-Ion battery.
Current matching and uniform brightness is inherent in series connection.
The ACT6310 incorporates a 30V high voltage switch.
Operating at 1.
2MHz, the device allows the use of very few tiny external components.
The low feedback voltage of 95mV minimizes power loss in the current setting resistor for better efficiency.
The ACT6310 is available in SOT-23 package and requires very few external devices for operation.
