Murata launches new 3.3Vin, 12A buck converter for low profile applications < 1.2mm

2024-07-19 | 返回

Murata today announced the launch of the PE24110, the newest compact, low-profile, and ultra-high efficiency step-down DC-DC converter solution. The PE24110 can deliver 12A per stage

output current from an input voltage range from 3.0V to 3.45V, and its output voltage is selected with external feedback resistors to be adjusted between 0.35 and 0.7V.

This solution is based on Murata’s advanced two-stage architecture and consists of a two-phase interleaved charge pump followed by an interleaved buck regulator stage. This power system greatly reduces the dependency on inductance for high efficiency solutions in small- footprint and height-constrained applications. This makes them the ideal step-down DC-DC converter solutions for low-profile point-of-load (POL) regulators, high-density, optical transceiver modules, core supplies, ASICs, and FGPAs.

Product features

>89% peak efficiency (at 3.3Vin/0.5Vo with 1.2mm z-height inductor)
>Extremely low input and output ripple
>Input voltage range of 3.0V to 3.45V (supports running off a nominal 3.3V bus supply)
>Output voltage set by external feedback resistors
>Output adjustment can be adjusted by external AVS DAC
>Can parallel up to four devices

"We are proud to bring these new compact, low-profile, and ultra-high efficiency step-down DC-DC converter solutions to market to alleviate the power pain points our customers face," says Steve Allen, vice president of power, pSemi® Corporation, a Murata Company "The PE24110 represent breakthroughs in peak efficiency, output current, output voltage, and more -- making them an ideal power solution for low output voltage applications.”

Package and availability

The PE24110 is offered on 4.0 × 3.2 mm QFN package. Samples are available now. Contact your regional sales representative for information about evaluation kits and volume-production parts.
