Boost, Sync Buck, Load Controller for Memory Backup (5V @ 1.5A) (PMP3008)
PMP3008 is an energy storage/power backup system. The input is a 1.8VDC rail that supplies power to memory. When the main 1.8VDC source is interrupted, the stored energy keeps the rail at 1.8VDC for a few seconds to allow an orderly power down. There are several POL converters that provide voltage rails to the system. The main IC used in the storage circuit are the TPS61030, TPS54317 and 2x TPS2411.
