Регуляторы напряжения - Импульсные регуляторы TPS61046YFFT

Импульсный повышающий DC-DC стабилизатор , регулируемый, 1.8В-5.5В (Vin), 4.5В-28В, 900мА, DSBGA-6

The TPS61046YFFT is a highly integrated Boost Converter designed for applications requiring high voltage and tiny solution size such as PMOLED panel and sensor module. The TPS61046 integrates a 30V power switch, input/output isolation switch and power diode. It can output up to 28V from input of a Li+ battery or two cell alkaline batteries in series. It operates with a switching frequency at 1MHz. This allows the use of small external components. The TPS61046 has an internal default 12V output voltage setting by connecting the FB pin to the VIN pin. Thus it only needs three external components to get 12V output voltage. The TPS61046 has typical 900mA switch current limit. It has 10ms built-in soft-start time to minimize the inrush current. When the TPS61046 is in shutdown mode, the isolation switch disconnects the output from input to minimize the leakage current. The TPS61064 also implements output short circuit protection, output overvoltage protection and thermal shutdown.
