**Description** The TPS6216X family is an easy to use synchronous step down DC-DC converter optimized for applications with high power density. A high switching frequency of typically 2.25MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by utilization of the DCS-Control topology. With its wide operating input voltage range of 3V to 17V, the devices are ideally suited for systems powered from either a Li-Ion or other battery as well as from 12V intermediate power rails. It supports up to 1A continuous output current at output voltages between 0.9V and 6V (with 100% duty cycle mode). **Features** DCS-Control Topology Input Voltage Range: 3 to 17 V Up to 1A Output Current Adjustable Output Voltage from 0.9 to 6 V Fixed Output Voltage Versions Seamless Power Save Mode Transition Typically 17µA Quiescent Current Power Good Output 100% Duty Cycle Mode Short Circuit Protection Over Temperature Protection Available in MSOP-8 and 2×2 mm WSON-8 Packages
