SLDS234B December 2017 – September 2018 TPS65218D0
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The device is designed to operate with an input voltage supply range between 2.7 and 5.5 V. This input supply can be from a single cell Li-Ion battery or other externally regulated supply. If the input supply is located more than a few inches from the TPS65218D0 additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An electrolytic capacitor with a value of 47 µF is a typical choice.
The coin cell back up input is designed to operate with a input voltage supply between 2.2 and 3.3 V This input should be supplied by a coin cell battery with 3-V nominal voltage.
