TEXAS INSTRUMENTS TPS63050RMWT 直流-直流开关降压-升压稳压器, 可调, 2.5 V-5.5 V输入, 2.5V-5.5V输出, 500mA输出, VQFN-12
The is an adjustable output, high efficiency tiny single inductor buck-boost converter in 12 pin VQFN package. This low quiescent current converter is suitable for applications where input voltage is higher or lower than the output. The continuous output current can go as high as 500mA in boost mode and as high as 1A in buck mode. The maximum average current in switches is limited to typical value of 1A. The TPS63050 regulates output voltage over complete input voltage range by automatically switching between buck or boost mode depending on input voltage by ensuring seamless transition between modes of operation. The buck-boost converter is based on a fixed frequency PWM controller using synchronous rectification to obtain highest efficiency. At low load currents, the converter enters power save mode to maintain high efficiency over the complete load current range. The output voltage is programmable using an external resistor divider or is fixed internally on the chip.
This device has limited built-in ESD protection. The leads should be shorted or device should be placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
