TPS61045DRBR (TEXAS INSTRUMENTS)

The TPS61045DRBR is a high-frequency digitally adjustable 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 1MHz, the device allows the use of small external components and together.
