Product Introduction
The TPS62175/7 is a high-efficiency synchronous step-down DC-DC converter based on DCS-control buck converter topology. With a wide input voltage range of 4.75V to 28V, the device is suitable for systems powered by multi-cell Li-ion batteries and 12V or higher impedance power rails, delivering output currents up to 500mA. The TPS62175/7 automatically enters power-save mode at light loads to maintain high efficiency across the entire load range. In addition, it features a sleep mode for powering applications with advanced power-saving requirements, such as ultra-low-power microcontrollers. The power-good output can be used for power sequencing and/or power-on reset. The device features a typical quiescent current of 22uA in normal mode and 4.8uA 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 2uA and the output is actively discharged. The TPS62175/7, available in adjustable and fixed output voltage versions, comes in a compact 2mm×3mm 10-pin WSON package.
