特点 Ultralow Power: I IN = 13μA Regulated Output Voltage: 3.3V ±4%, 5V ±4% 5V Output Current: 50mA (V IN >/= 3.0V) 3.3V Output Current: 40mA (V IN >/=2.5V) No Inductors NeededVery Low Shutdown Current: <1μA Shutdown Disconnects Load from V IN Internal Oscillator: 600kHzShort-Circuit and Overtemperature ProtectedUltrasmall Application Circuit: (0.052 Inch2)6-Pin SOT-23 Package典型应用典型应用描述描述 The LTC?1754 is a micropower charge pump DC/DC converter that produces a regulated output. The input voltage range is 2V to 4.4V for 3.3V output and 2.7V to 5.5V for 5V output. Extremely low operating current and a low external parts count (one flying capacitor and two small bypass capacitors at V IN and V OUT ) make the LTC1754 ideally suited for small, battery-powered applications. The total component area of the application circuit shown below is only 0.052 inch2. The LTC1754 operates as a Burst Mode? switched capacitor voltage doubler to produce a regulated output. It has thermal shutdown capability and can survive a continuous short circuit from V OUT to GND. The LTC1754 is available in a 6-pin SOT-23 package.
