1.1MHZ BOOST CONVERTER WITH 30V INTERNAL FET SWITCH
February 2012
GENERAL DESCRIPTION
The IS31PW3500 is a constant current step-up converter. The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness as well as constant output voltage to drive other devices. The IS31PW3500 switches at 1.1MHz, allowing the use of tiny external ponents. The input and output capacitor can be as small as 1μF, saving space and cost versus alternative solutions. A low 0.25V feedback voltage minimizes power loss in the current setting resistor for better efficiency. The IS31PW3500 is available in small DFN-8, 2mm × 2mm...
