SLVSBO4C – OCTOBER 2012 – REVISED DECEMBER 2014 TPS6273x Programmable Output Voltage Ultra-Low Power Buck Converter
With Up to 50 mA / 200 mA Output Current
1 Features 3 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 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 to supply the rail to low-voltage electronics.
The regulated output has been optimized to provide
high efficiency across low-output currents ( 4.6 V -> 4.6 V from bench power supply
