LTC3129EMSE#PBF

LTC3129 is a high efficiency, 200mA buck-boost DC/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. This device employs an ultralow noise, 1.2MHz PWM switching architecture that minimizes solution foot print by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start simplify the design. It is widely used in application such as industrial wireless sensor nodes, post-regulator for harvested energy, solar panel post-regulator/charger, intrinsically safe power supplies, wireless microphones, avionics-grade wireless headsets etc.
