LTC3129IUD-1#PBF

LTC3129-1 is a high efficiency, 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 powerpoint control (MPPC) capability that ensures maximum power extraction from non-ideal power sources such as photo voltaic panels. It 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. For high efficiency operation at light loads, automatic Burst Mode operation can be selected, reducing the quiescent current to just 1.3µA. It is 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.
