1.0MHZ BOOST CONVERTER WITH 38V INTERNAL MOSFET SWITCH April 2024 GENERAL DESCRIPTION IS31BL3508A 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 0.3V. The IS31BL3508A operates at a constant switching frequency of 1.0MHz to allow for small ponent size. IS31BL3508A Features an over voltage shutdown pin which prevents the output voltage from exceeding 38V (Typ.) in...
