The LTC3130/LTC3130-1 are high efficiency, low noise, 600mA buck-boost converters with wide VIN and VOUT ranges. For high efficiency operation at light loads, BurstMode operation can be selected, reducing the quiescent current to just 1.6µA. Converter start-up is achieved from sources as low as 7.5µW. TheLTC3130/LTC3130-1 employ an ultralow noise, 1.2MHz PWM architecture that minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Built-in loop compensation and soft-start reduces external parts count and simplifies the design. Features include an accurate RUN comparator threshold to allow predictable regulator turn-on and a maximum power point control (MPPC) capability that ensures maximum power extraction from non-ideal sources such as photovoltaic panels. The LTC3130-1 includes an internal voltage divider to provide four selectable fixed output voltages. Additional features include a power good output, an external VCC input and thermal shutdown. The LTC3130 and LTC3130-1 are available in thermally-enhanced 20-lead 3mm × 4mm QFN and 16-lead MSOP packages.
