Описание

The TPS60151 is a switched capacitor voltage converter which produces a regulated, low noise, and low-ripple output voltage of 5 V from an unregulated input voltage. It maintains 5-V regulation even when VIN is greater than 5 V.The 5-V output can supply a minimum of 140-mA current.The TPS60151 has built-in current limit and output reverse current protection that are ideal for HDMI, USB OTG and other battery powered applications.TPS60151 operates in skip mode when the load current falls below 8 mA under typical condition. In skip mode operation, quiescent current is reduced to 90 µA.Only 3 external capacitors are needed to generate the output voltage, thereby saving PCB space.Inrush current is limited by the soft-start function during power on and power transient states. The TPS60151 operates over a free air temperature range of –40°C to 85°C. The device is available with a small 2-mm × 2-mm 6-pin SON package (QFN).
