ACT4050 5V/3A Output Applicationc
c: D1 is a 30V, 5A Schottky diode with low forward voltage, a B530C equivalent. C4 can be either a ceramic capacitor (Panasonic
ECJ-3YB1C226M) or SP-CAP (Specialty Polymer) Aluminum Electrolytic Capacitor such as Panasonic EEFCD0J470XR. The SP-Cap
is based on aluminum electrolytic capacitor technology, but uses a solid polymer electrolyte and has very stable capacitance
characteristics in both operating temperature and frequency compared to ceramic, polymer, and low ESR tantalum capacitors.
