LTC3130IUDC-1#PBF

LTC3130-1 is a high efficiency, low noise, 600mA buck-boost converter with wide VIN and VOUT ranges. For high efficiency operation at light loads, burst mode operation can be selected, reducing the quiescent current to just 1.6µA. Converter start-up is achieved from sources as low as 7.5µW. 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. It is widely used in application such as long-life, battery-operated instruments, portable military radios, low power sensors, solar panel post-regulator/charger etc.
