Power ProductsUltraBK™

The MYTxx series of Ultra-Thin, Fully Integrated 2-stage Point-of Load Regulator module is based on combination with Murata's proprietary adiabatic or lossless charge pump technology.
The module integrates all passive components including inductor in one package and it's technology is ideally suited to provide step-down voltage conversion for 2/3cell battery or 12Vin Point-of Load application where high efficiency, low profile and small solution size are essential.

Murata's Unique Two-stage Architecture for Step Down conversion

A highly flexible multi-stage architecture comprising a patented “pipeline” stage switched-capacitor network (charge pump) combined with buck stage.

Virtually lossless stage irrespective of conversion ratio! Efficiency is largely independent of the difference between input and output voltage. Capacitors do most of the work, enabling greatly reduced inductor sizing. Uses low voltage FETs throughout the power train. Built on standard CMOS.

Interleaved Operation for Lower Ripple/EMI and Better Transient Performance

Interleaved Charge Pump stage leads to Lower input ripple Lower EMI emissions Interleaved Buck Converter stage leads to Lower output ripple Better transient performance
