The AME5131 is a high-frequency boost converter dedicated for LCD bias supply and white LED applications for cellular phone backlighting, PDAs, and other hand-held devices. The part can also be used to generate standard 3.3 V/5 V to 12 V power conversions. The AME5131 has an internal 400mA switch current limit, offering lower output voltage ripple. The 32A low quiescent current together with an optimized control scheme, allows device operation at high efficiencies and maintains long battery lifetime. AME5131 uses SOT-25 package and gives a small size solution.
