TPS60502数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The TPS6050x devices are a family of switched capacitor voltage converters, designed specifically for space-critical battery-powered applications. The TPS6050x step-down charge pumps generate a regulated, fixed 3.3-V, 1.8-V, 1.5-V, or adjustable output voltage. Only four small ceramic capacitors are required to build a complete high-efficiency DC–DC charge pump converter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selects between three different conversion modes. The output can deliver a maximum of 250-mA output current. The power good function supervises the output voltage and goes high when the output voltage rises to 97% of the nominal value. The TPS6050x devices come in a micro-small 10-pin VSSOP package.
