Hi all, I'm searching for a low noise switching supply IC. The goal is to get +5V/200mA and -5V/200mA from a +3.3V with less than 5mV ripple. Ideal one IC. Found so far: LT1534, MAX710, MAX735. Any good ideea appreciated. thank you, Vasile -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
