The TLV61046A is a boost DC-DC converter integrating a power switch, an input to output isolation switch, and a rectifier diode. The device supports up to 28-V output with the input voltage ranging from 1.8 V to 5.5 V. The TLV61046A adopts the current-mode control with adaptive constant off-time. The switching frequency is quasi-constant at 1.0 MHz. The isolation switch disconnects the output from the input during shutdown to minimize leakage current.

The following design procedure can be used to select component values for the TLV61046A.
