For Low‐Power Wireless Power‐Supply Solutions Ultra‐Low ICs With an Integrated Schottky Diode Bridge and LDO Regulator

by donpedro

Torex Semiconductor Ltd. 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.

Torex will continue to swiftly develop products that meet market needs and contribute to a richer and more abundant society.

Features of the XCM414 series
・Integrates a diode bridge and LDO regulator in a single package
・Uses the ultra‐low and small USP‐8B10 package (2.6 × 2.9 × h0.33mm)
