LTC1516CS8#PBF

LINEAR TECHNOLOGY  LTC1516CS8#PBF  芯片, 电荷泵 5V

The is a micro-power DC/DC charge-pump Converter that produces a regulated 5V output from a 2 to 5V supply. Extremely low supply current and low external parts count make the LTC1516 ideally suited for small, light load battery-powered applications. Typical efficiency exceeds 70% with load currents between 50µA and 50mA. Modulating the SHDN pin keeps the typical efficiency above 70% with load currents all the way down to 10µA. The LTC1516 operates as either doubler or tripler depending on VIN and output load conditions to improve overall efficiency. The part has thermal shutdown and can survive a continuous short from VOUT to GND. In shutdown the load is disconnected from VIN.
