Murata 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 3.0 V to 3.45 V, and its output voltage is selected with external feedback resistors to be adjusted between 0.35 and 0.7 V.
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 FPGAs.
Key features
- 89% peak efficiency (at 3.3 Vin/0.5 Vo with 1.2 mm z-height inductor)
- Extremely low input and output ripple
- Input voltage range of 3.0 V to 3.45 V (supports running off a nominal 3.3 V 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.”
