Integrated Power Management Unit IP Cores
Silicon-Proven 40 nm Series
Vidatronic’s 40 nm integrated PMU IP cores are specifically designed to function together as a single PMU for integration into a larger ASIC or SoC; however, they can also be used separately in other applications. This series contains a dual-mode low dropout (LDO) voltage regulator equipped with Vidatronic’s patented Power Quencher® technology, a buck DC-DC converter, a low-power voltage reference, a high-accuracy bandgap reference, and a dual power switch, all silicon-proven in 40 nm.
The integrated PMU IP cores operate with ultra-low levels of power consumption without sacrificing other areas of performance. The Power Quencher® LDO does not require the external output capacitor that is typically needed in an LDO for loop stability and noise reduction. This saves component count, board space and cost, and improves overall system reliability. The buck DC-DC converter has optimized clocking options which help to eliminate spurious emissions from beat frequencies and harmonics that would otherwise be present, resulting in much lower overall system noise.
