The TPS6217x is a high efficiency synchronous step-down DC/DC converter, based on the DCS-Control™ topology.
With a wide operating input voltage range of 4.75 V to 28 V, the device is ideally suited for systems powered from multi cell Li-Ion as well as 12 V and even higher intermediate supply rails, providing up to 500-mA output current.
The TPS6217x automatically enters power save mode at light loads, to maintain high efficiency across the whole load range. As well, it features a sleep mode to supply applications with advanced power save modes like ultra low power micro controllers. The power good output may be used for power sequencing and/or power on reset. 2、Function Description: DCS-Control™ Topology Input Voltage Range 4.75 V to 28 V Quiescent Current Typically 4.8 µA (Sleep Mode) 100% Duty Cycle Mode Active Output Discharge Power Good Output Output Current of 500 mA Output Voltage Range 1 VDC to 6 V Switching Frequency of Typically 1 MHz Seamless Power Save Mode Transition Undervoltage Lockout Short Circuit Protection Over Temperature Protection Available in 2-mm × 3-mm 10-pin WSON Package 3、Description of each function module:
