LTC3129IMSE#PBF

LINEAR TECHNOLOGY  LTC3129IMSE#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 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. Additional features include a power good output, less than 10nA of shutdown current and thermal shutdown.
