1 / 8 page IS31PW3500 Integrated Silicon Solution, Inc. – www.issi.com 1 Rev.A, 12/30/2011 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 components. 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 package. FEATURES 2.4V to 5.5V input range 26V output with over voltage protection High efficiency :85 % typical PWM dimming control Internal high power 30V MOSFET switch Fast 1.1MHz switching frequency Small, low-profile inductors and capacitors DFN-8, 2mm × 2mm package RoHS compliant and 100% lead (Pb)-free APPLICATIONS Mobile phone Digital still camera PDAs, handheld computers MP3 players GPS receivers TYPICAL APPLICATION CIRCUIT Figure 1 Typical Application Circiut |
