概觀

IS31BL3506B 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 is set using an external, low value sensing resistor. The device adjusts the PWM duty cycle of the switch to maintain the voltage at the FB pin at a value of 0.2V. The IS31BL3506B operates at a constant switching frequency of 1.0MHz to allow for small component size. IS31BL3506B features an over voltage shutdown pin which prevents the output voltage from exceeding 35V (typ.) in the case of an open circuit condition. The device is offered in a tiny TSOT-23-6 and SOT-23-6 package and a temperature rating from -40°C ~ +85°C.
