Texas Instruments TPS61046 28V Output Voltage Boost Converter
Texas Instruments TPS61046 28V Output Voltage Boost Converter is a highly integrated boost converter designed for applications requiring high voltage and tiny solution size. These are ideal for applications such as PMOLED panel and sensor module. The TPS61046 from Texas Instruments integrates a 30V power switch, input/output isolation switch, and power diode. It can output up to 28V from input of a Li+ battery or two cell alkaline batteries in series. This device operates with a switching frequency at 1MHz. This allows the use of small external components. The TPS61046 has an internal default 12V output voltage setting by connecting the FB pin to the VIN pin. Thus it only needs three external components to get 12V output voltage.
