IS31BL3508B - Lumissil

IS31BL3508B 1.0MHZ BOOST CONVERTER

IS31BL3508B is a boost converter featuring an integrated MOSFET switch designed for driving series strings of LED or other device. Input operating voltage range is 2.7V~5.5V. The device regulates the LED load current and it is controlled by an external, low value sensing resistor. The device adjusts the PWM duty cycle of the switch to maintain the voltage at.
