TPS61200DRCT

The TPS6120x is a family of low-input-voltage synchronous boost converters. The devices support an input voltage range of 0.3V to 5.5V, providing power solutions for products powered by one, two, or three alkaline, NiCd, or NiMH cells, or single-cell Li-Ion or Li-Polymer batteries. They are also used in fuel cell- or solar cell-powered devices, where the ability to handle low input voltages is critical. When using a single Li-Ion or Li-Polymer cell discharged to 2.6V, the device can deliver up to 600mA of output current at a 5V output.

Applications

• Single-cell, two-cell, and three-cell alkaline, NiCd, or NiMH battery-powered products, or single-cell lithium battery-powered products
