Product Description

The TPS63051RMWT is a fixed 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 a typical value of 1A. The TPS63051 regulates output voltage over the 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.
Fixed output voltage of 3.3V
Input voltage range from 2.5V to 5.5V
0.5A continuous output current at VIN >= 2.5V and VOUT = 3.3V
Efficiency is greater than 90% in boost mode and greater than 95% in buck mode
2.5MHz typical switching frequency
Adjustable average input current limit and soft start time
Quiescent current is less than 60µA
Power save mode and overtemperature protection
Load disconnect during shutdown
Operating temperature range from -40°C to 85°C
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.
