The TPS61045 device is a high-frequency boost converter with digitally-programmable output voltage and true shutdown. During shutdown, the output is disconnected from the input by opening the internal input switch. This allows a controlled power-up and power-down sequencing of the display. The output voltage can be increased or decreased in digital steps by applying a logic signal to the CTRL pin. The output voltage range, as well as the output voltage step size, can be programmed with the feedback divider network. With a high switching frequency of up to 1 MHz, the TPS61045 device allows the use of small external components, and together, with the small 8-pin VSON package, a minimum system solution size is achieved.
