Ricoh launches 6 A Load Switch with Voltage Detector
Osaka, Japan, 01 March 2019 – Ricoh Electronic Devices Co., Ltd. in Japan has launched the R5542, a versatile load switch embedded in an ultra-small wafer level chip scaled package and is able to switch currents up to 6 A. Target applications are mobile devices such as smartphones and tablets. Load switches are integrated electronic switches used to turn on and turn off power rails. Such kind of solution is smaller and more cost efficient compared to traditional relays. In addition, load switches have various additional features, which are not available in traditional solutions.
