The TPS61097A-33 provides a power supply solution for products powered by either a
single-cell, two-cell, or three-cell alkaline, NiCd, or NiMH, or one-cell Li-Ion or Li-polymer
battery. They can also be used in fuel cell or solar cell powered devices where the capability of
handling low input voltages is essential. Possible output currents depend on the input-to-output
voltage ratio. The devices provide output currents up to 100 mA at a 3.3-V output while using a
single-cell Li-Ion or Li-Polymer battery. The boost converter is based on a current-mode controller
using synchronous rectification to obtain maximum efficiency. The maximum average input current is
limited to a value of 400 mA. The converter can be disabled to minimize battery drain. During
shutdown, the battery is connected to the load to enable battery backup of critical functions on
the load. The device is packaged in a 5-pin SOT-23 package (DBV) measuring 2.8 mm ×
2.9 mm.
