The TLV61046A is a highly-integrated boost converter designed for applications requiring high voltage and small solution size such as PMOLED panel power supply and sensor module. 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 input of a Li+ battery or two-cell alkaline batteries in series.

One common issue with conventional boost regulators is the conduction path from input to output even when the power switch is turned off. It creates three problems, which are inrush current during start-up, output leakage current during shutdown, and excessive over load current. In the TLV61046A, the isolation switch is turned off under shutdown mode and over load conditions, thereby opening the current path. Thus, the TLV61046A can truely disconnect the load from the input voltage and minimize the leakage current during shutdown mode.

The TLV61046A operates with a switching frequency at 1.0 MHz. This allows 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. Thus, it only needs three external components to get 12-V output voltage. The TLV61046A has typical 980-mA switch current limit. It has 7-ms built-in soft start time to minimize the inrush current. The TLV61046A also implements output short circuit protection, output overvoltage protection, and thermal shutdown.
