描述 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.特性Wide Input Voltage Range From 1.8 V to 6.5 V Regulated 3.3-V, 1.8-V, 1.5-V, or Adjustable Output Voltage Up to 250-mA Output Current Up to 90% Efficiency Output Voltage Tolerance 3% Over Line, Load,and Temperature Variation Device Quiescent Current Less Than 40 μA Output Voltage Supervisor Included (Power Good) Internal Soft Start Load Isolated From Battery During Shutdown Overtemperature and Overcurrent Protected Micro-Small 10-Pin VSSOP Package EVM Available, TPS60500EVM-193
