TLV61046ADBVT DC-DC Switching Boost Converter, 1 MHz, 3.3V-28V, and SOT-23-6

The theTLV61046ADBVT is a highly integrated boost converter that can be used in PMOLED panels, LCD bias supplies, and sensor modules. A 30-V power switch, an input to output isolation switch, and a rectifier diode are all included in the TLV61046ADBVT,  From the input of a Li+ battery or two alkaline batteries in series, it may produce up to 28 V.

The TLV61046ADBVT  operates with a switching frequency of 1.0 MHz. This allows the use of small external components. The TLV61046ADBVT  has an internal default 12-V output voltage setting by connecting the FB pin to the VIN pin. The TLV61046ADBVT  is available in a 6-pin 3-mm x 3-mm SOT23-6 package.

TLV61046ADBVT Application Circuit

The TLV61046A operates with a switching frequency of 1.0 MHz. This makes it possible to use small external components. By connecting the FB pin to the VIN   pin.  the TLV61046A  has an internal default 12-V output voltage setting. As a result, it only requires three external components to provide a 12-volt output voltage,  The TLV61046A  has a typical switch current limit of 980-mA. It has a 7-ms soft-start time built in to reduce inrush current. The isolation switch disconnects the output from the input while the TLV61046A  is in shutdown mode, reducing leakage current. The TLV61046A  additionally includes output short circuit, output overvoltage, and thermal shutdown protection.

TLV61046ADBVT is a boost converter with a power diode and isolation switch 1.8V to 5.5V 0.9A 28V Output 6-Pin SOT-23 T/R.
