Description: Switching Regulator, Current/voltage-…

The TPS6217x is a high efficiency synchronous step1• DCS-Control™ Topology
down DC/DC converter, based on the DCS-Control™ • Input Voltage Range 4.75 V to 28 V topology.
• Quiescent Current Typically 4.8 µA (Sleep Mode)
With a wide operating input voltage range of 4.75 V
• 100% Duty Cycle Mode to 28 V, the device is ideally suited for systems
• Active Output Discharge powered from multi cell Li-Ion as well as 12 V and
• Power Good Output even higher intermediate supply rails, providing up to
500-mA output current.
• Output Current of 500 mA
• Output Voltage Range 1 VDC to 6 V The TPS6217x automatically enters power save
mode at light loads, to maintain high efficiency across
