DESCRIPTION
●The TPS6273X family provides a highly integrated ultra low power buck converter solution that is well suited for meeting the special needs of ultra low power applications such as energy harvesting. The TPS6273X provides the system with an externally programmable regulated supply in order to preserve the overall efficiency of the power management stage compared to a linear step down converter. This regulator is intended to step down the voltage from an energy storage element such as a battery or super capacitor in order to supply the rail to low voltage electronics. The regulated output has been optimized to provide high efficiency across low output currents (<10 µA) to high currents (200 mA).
