ACT4060A 5V/2A Output Application

: D1 is a 40V, 3A Schottky diode with low forward voltage, an IR 30BQ040 or SK34 equivalent. C4 can be either a ceramic capacitor

The SP-Cap is based on aluminum electrolytic capacitor technology, but uses a solid polymer electrolyte and has very stable capaci-

tance characteristics in both operating temperature and frequency compared to ceramic, polymer, and low ESR tantalum capacitors.
