DESCRIPTION

The TLV61046A is a highly integrated boost converter designed for applications such as PMOLED panels, LCD bias supplies, and sensor modules. The TLV61046A integrates a 30V power switch, an input-to-output isolation switch, and a rectifier diode. This device converts input voltages from a single lithium-ion battery or two alkaline batteries (in series) to output voltages up to 28V.

The TLV61046A operates at a switching frequency of 1.0MHz, enabling the use of small external components. By connecting the FB pin to the VIN pin, the default internal output voltage can be set to 12V, requiring only three external components to achieve a 12V output voltage.

The TLV61046A features a typical switch current limit of 980mA and a built-in 7ms soft-start time to reduce inrush current. When the TLV61046A is in shutdown mode, the isolation switch disconnects the output from the input to minimize leakage current. The TLV61046A also features output short-circuit protection, output overvoltage protection, and thermal shutdown protection.

The TLV61046A is available in a 6-pin 3mm × 3mm SOT23-6 package.
