Integrated slew rate controlled switch optimising 1V core in mobile systems

FPF1018, IntelliMAX, a slew-rate-controlled load switch, guarantees that mobile systems operate with more reliable and stable power at very low voltage core line for steady and transient operations than current existing discrete solutions.

Recent mobile systems require the very low voltage core, realised by smaller process geometries, to employ more function blocks with low power consumption and improve performance of microprocessors. For the mobile systems to perform properly, low voltage power must be delivered efficiently and stably, even with high currents, whether it's transient or steady state. As needed core voltage decreased, it became important to conform to stringent regulations and transient specifications. In fact, VCORE of multimedia application processors (MAPs) in mobile applications is becoming lower and MAPs with VCORE of 1V have appeared, which requires stable power within range of 0.9-1.1V at least.
