TPS61098x Synchronous Boost Converters

Texas Instruments TPS61098x Synchronous Boost Converters are an ultra low power solution for battery-powered products. These can be powered by either a one or two-cell alkaline, NiCd or NiMH, one-cell coin cell or one-cell Li-Ion or Li-polymer battery. These integrate either a Low-dropout Linear Regulator (LDO) or a load switch with a boost converter. This provides two output rails. The boost output V(MAIN) is designed as an always-on supply for a main system. The LDO or load switch output V(SUB) is to power peripheral devices. The TPS61098x has two modes controlled by MODE pin: Active mode and Low Power mode. In Active mode, both outputs are enabled with enhanced response performance. In Low Power mode, the LDO or load switch is disabled to disconnect peripherals.
