Non-Isolated DC-DC converter moduleUltraCP™

The MYCxx series of Ultra-Thin, Fully Integrated Charge pump, Capacitor divider module is based on Murata's proprietary adiabatic or lossless charge pump technology.
The module integrates all passive components including inductor in one package and the technology is ideally suited to provide "Lossless" step-down voltage conversion for intermediate bus system to support downstream Point-of-Load and enable highest level efficiency.

From Centralized Power Supply to Dispersed Power Supply

We have replaced the intermediate bus converter from a brick type converter to a charge pump and placed it near the Point of Load (POL) or similar power supply circuit. This reduces wiring loss by about 60% to improve the overall system efficiency.
