TPS610981DSET

TEXAS INSTRUMENTS  TPS610981DSET  同步升压驱动器, 带集成LDO开关, 0.7V-4.5V输入, 3.3V输出, 350 mA 电流限制, WSON-6

The is a Synchronous Boost Converter with integrated LDO/load switch. It is suitable for products powered by either one-cell or two-cell alkaline, NiCd or NiMH, one-cell coin cell or one-cell li-ion or li-polymer battery. It integrates either a low-dropout linear regulator LDO or a load switch with a boost converter and provides two output rails. The boost output VMAIN is designed as an always-ON supply for a main system and the LDO or load switch output VSUB is to power peripheral devices. It 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. It consumes only 300nA quiescent current and can achieve up to 88% efficiency at 10µA load in low power mode. It supports automatic pass-through function.
