Detailed Description

The TLV61046A integrates a 30-V power switch, an input to output isolation switch, and a rectifier diode. It can output up to 28 V from an input of a Li+ battery or two alkaline batteries in series. The device operates with a switching frequency at 1.0 MHz, allowing the use of small external components. The TLV61046A has an internal default 12-V output voltage setting by connecting the FB pin to the VIN pin, requiring only three external components to achieve 12-V output voltage.
