LINEAR TECHNOLOGY LT3491EDC#TRMPBF 发光二极管驱动器, 1输出, 升压逐步上升, 2.5V-12V输入, 2.3MHz开关, 27V/200mA输出, DFN-6
The is a fixed frequency step-up DC/DC Converter specifically designed to drive up to six white LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The device features unique high-side LED current sense that enables the part to function as a one wire current source, one side of the LED string can be returned to ground anywhere, allowing a simpler one wire LED connection. Traditional LED drivers use a grounded resistor to sense LED current, requiring a 2-wire connection to the LED string. The 2.3MHz switching frequency allows the use of tiny inductors and capacitors. A single pin performs both shutdown and accurate LED dimming control.
