Ultra-Low ICs With an Integrated Schottky Diode Bridge and LDO Regulator XCM414 Series

Nov 1, 2017

Torex Semiconductor Ltd. (Tokyo Japan: President, Koji Shibamiya, 6616: 2nd section at Tokyo Stock Exchange) has launched multichip-module power ICs that integrate four Schottky diodes and an LDO regulator.


With the increase in recent years of smartcards and other products that are equipped with a thin lithium ion battery or super capacitor, a demand for simple wireless charging has emerged.


The XCM414 series connects four Schottky diodes in a bridge inside the package to perform full-wave rectification of AC (alternating current) input, and this can be input into an LDO regulator following smoothing by an external capacitor. The integrated LDO regulator supports high-voltage input and outputs a stable voltage. By incorporating the Schottky diode bridge and LDO regulator that are required for simple wireless charging in the same package, a stable DC voltage can be output from an AC voltage input.


The package is an ultra-low type with a height of only 0.33mm, and is also ideal for smartcards, IoT devices that require a small size and low power consumption, and hearable devices (wireless earphones, hearing aids, etc.), for which Torex has strengthened its lineup in recent years.
