LTC3129IMSE-1#PBF

LINEAR TECHNOLOGY  LTC3129IMSE-1#PBF  直流-直流开关降压-升压稳压器, 可调, 1.92V-15V输入, 1.4V-15.75V输出, 200mA输出, MSOP-16

The is a high-efficiency buck-boost DC-to-DC Converter with a wide VIN and VOUT range. It includes an accurate RUN pin threshold to allow predictable regulator turn-ON and a maximum power point control MPPC capability that ensures maximum power extraction from non-ideal power sources such as photovoltaic panels. The LTC3129-1 employs an ultralow noise, 1.2MHz PWM switching architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start simplify the design. For high efficiency operation at light loads, automatic Burst Mode® operation can be selected, reducing the quiescent current to just 1.3µA. To further reduce part count and improve light load efficiency, the LTC3129-1 includes an internal voltage divider to provide eight selectable fixed output voltages. Additional features include a power good output, less than 10nA of shutdown current and thermal shutdown.
