Step-Up Boost DC/DC Converters Integrated Switch, Texas Instruments### 直流/直流开关调节器转换器(集成开关),Texas InstrumentsTexas Instruments 的此系列高度集成的高效开关稳压器包括步升(升压)、步降(降压)、步升/降(增压/降压)和反相类型,为每个直流稳压器应用提供高效的解决方案。
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.
