The TPS62175DQCT 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 to 28V, the device is ideally suited for systems powered from multi cell Li-ion as well as 12V and even higher intermediate supply rails, providing up to 500mA output current. The TPS62175DQCT 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. The device features a typical quiescent current of 22μA in normal mode and 4.8μA in sleep mode. In sleep mode, the efficiency at very low load currents can be increased by as much as 20%. In shutdown mode, the shutdown current is less than 2μA and the output is actively discharged.
