I. FlexiCP™: Lossless Charge Pump Technology, Redefining Step-Down Conversion Efficiency

FlexiCP™ is a series of DC-DC charge pump ICs developed by Murata based on its proprietary adiabatic (lossless) charge pump technology, with the PE252xx series as its flagship product. Primarily designed for step-down conversion applications in intermediate bus systems, it provides highly efficient power supply support for downstream point-of-load (PoL) applications, completely overcoming the efficiency bottlenecks and size constraints of traditional step-down solutions.

1. Core Technical Principles

Unlike traditional inductive step-down converters, FlexiCP™ employs Murata’s proprietary switched-capacitor architecture, which eliminates the need for inductors and achieves lossless voltage conversion through the charging and discharging of capacitors. Its core advantage lies in ‘adiabatic charge pump technology’, which minimises energy loss during charge transfer to achieve conversion efficiency close to the theoretical maximum. Furthermore, the product integrates high-performance FETs (field-effect transistors) and a charge pump control architecture, enabling stable step-down conversion without the need for complex external components, thereby significantly simplifying the circuit design process.

2. Key Advantages

High conversion efficiency is the most prominent feature of FlexiCP™. It maintains exceptionally high efficiency across a wide input voltage range, particularly under light-load conditions, where it continues to deliver outstanding energy efficiency—far surpassing traditional inductor-based buck solutions—effectively reducing the device’s power consumption and heat generation. Furthermore, the product supports parallel operation of multiple devices, allowing the output current to be flexibly scaled according to actual power requirements to meet the power supply demands of various scenarios. In terms of packaging design, FlexiCP™ utilises a compact package; the design, which eliminates the need for an inductor, further reduces the PCB footprint, perfectly aligning with the design requirements of high-density circuit boards and providing robust support for the miniaturisation and slimline design of equipment.

3. Typical Application Scenarios

FlexiCP™ is widely used in data centres, servers, telecommunications equipment and other scenarios with stringent requirements for power supply efficiency and compactness. As the core of step-down conversion in intermediate bus systems, it provides a stable power supply to core chips such as DSPs, ASICs and FPGAs. At the same time, its low power consumption and compact size make it suitable for high-end consumer electronics and industrial control equipment, helping devices achieve high efficiency, energy savings and compact designs.

II. FlexiBK™: High-Efficiency Synchronous Buck Conversion for Demanding Power Supply Applications

The FlexiBK™ series is Murata’s range of synchronous buck converters, with the PE24110 as a representative model. Thanks to its ultra-high efficiency, low ripple and high reliability, it serves as an ideal power supply solution for space-constrained and noise-sensitive applications, filling a gap in the market for high-performance products in medium-to-high power buck conversion scenarios.

1. Core Technical Principles

FlexiBK™ utilises a synchronous buck topology. Through the incorporation of a high-performance synchronous rectifier, it significantly reduces conduction losses and achieves efficient conversion across a wide input voltage range. The product integrates comprehensive control circuits and protection mechanisms, supporting flexible adjustment of the output voltage via an external feedback resistor. It can also be paired with an external AVS DAC (Adaptive Voltage Scaling Digital-to-Analogue Converter) to enable precise fine-tuning of the output voltage, meeting the individual power supply requirements of different loads. Its unique circuit design effectively suppresses output ripple and reduces electromagnetic interference (EMI), ensuring the stability and purity of the power supply.

2. Key Advantages

FlexiBK™ boasts exceptionally high conversion efficiency, maintaining outstanding energy efficiency across the entire load range, thereby effectively reducing power loss and extending the device’s battery life. Its low ripple performance is another key feature, providing a stable and clean power supply for noise-sensitive components and preventing voltage fluctuations from affecting their operational performance. Furthermore, the product utilises a compact package, making it suitable for space-constrained applications, whilst incorporating multiple protection functions such as overcurrent protection (OCP), overvoltage protection (OVP) and undervoltage lockout (UVLO), which significantly enhance product reliability and service life whilst reducing equipment failure rates.
