XCM414 Series

Voltage Regulator with Bridge Diode for Wireless Power Receiver

The XCM414 series consist of four Schottky Barrier Diodes (SBD) and a positive voltage regulator (VR). These four SBDs configure a bridge circuit and it performs the full-wave rectification of an AC input so that the positive voltage regulator can generate DC output.

The VR consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor. The output voltage is preset at 3.3V in the IC as a standard value, and it is selectable in 0.1V increments within the range of 2.0V to 12V using laser trimming technologies. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors.

The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level.

The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption.
