A4490 Overview
Designed to provide the power supply requirements of printers, office automation, industrial, and portable equipment, the A4490 provides three high current, high performance, switching regulator outputs with independent soft start. High frequency switching allows selection of inexpensive inductors and small ceramic output capacitors. The turn-on cycles of the regulators are interleaved to minimize stresses on the...
