TPS62177DQCR

Description Based on the DCS-ControlTM topology, the TPS6217x is a high efficiency synchronous step-down DC/DC converter.   With an operational input voltage range of 4.75 V to 28 V, the device is appropriate for systems powered by multi-cell Li-ion batteries as well as 12 V and even higher intermediate supply rails, offering up to 500-mA output current.  
The TPS6217x enters power save mode automatically at low loads to maintain excellent efficiency across the whole load range. It also has a sleep mode to provide sophisticated power saving options to applications such as ultra low power micro controllers.
The power good output can be utilized for power sequencing as well as power on reset.  
The gadget has a typical quiescent current of 22 A in normal mode and 4.8 A in sleep mode. In sleep mode, the efficiency at very low load currents can be boosted by up to 20%. In shutdown mode, the shutdown current is less than 2 A, and the output is actively discharged.  
The TPS6217x, which is available in both adjustable and fixed output voltage versions, is housed in a compact 2-mm x 3-mm 10-pin WSON package.
