TPS610981 Ultra Low Quiescent Current Boost Evaluation Module
This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
The TPS61098 provides an ultra-low quiescent power supply solution for products powered by either a single cell or two-cell alkaline, one-cell coin cell battery or one-cell Li-Ion or Li-polymer battery. It integrates a load switch or LDO, and can provide two separate output power rails. The main output VMAIN is an always-on output with 2V minimum voltage, and the additional output VSUB is the output of internal load switch or LDO, designed to supply a peripheral device.
The TPS61098 can provide total output currents up to 30 mA at a 3.3V output even when input voltage is decreased to 0.7V. The boost is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents.
