LTC1751EMS8-3.3#PBF

LINEAR TECHNOLOGY  LTC1751EMS8-3.3#PBF  芯片, 直流/直流转换器, 2-5.5V, 0.1A, 3.3V, 8MSOP

The is a micro-power DC/DC charge-pump Converter that produces a regulated output voltage at up to 100mA. The input voltage range is 2 to 5.5V. Extremely low operating current and low external parts count makes it ideally suited for small, battery-powered applications. It operates as Burst Mode™ switched capacitor voltage doublers to achieve ultralow quiescent current. It has thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. The PGOOD pin on the LTC1751-3.3 indicates when the output voltage has reached its final value and if the output has an undervoltage fault condition. The FB pin of the adjustable LTC1751 can be used to program the desired output voltage or current. An optional soft-start capacitor may be used at the SS pin to prevent excessive inrush current during start-up.
