Product Summary
The TPS61045DRBR is a high frequency boost converter with digitally programmable output voltage and true shut- down. During shutdown the output is disconnected from the input by opening the internal input switch. This allows a controlled power up/down sequencing of the display. The output voltage can be increased or de- creased 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 fre- quency of up to 1 MHz the TPS61045DRBR5 allows the use of small external components and together, with the small 8-pin QFN package, a miminum system solution size is achieved. The applications of the TPS61045DRBR include LCD Bias Supply For Small to Medium LCD Displays and OLED Display Power Supply.
