FEATURES
s s s s s s s s s s s DESCRIPTIO Ultralow Power: IIN = 13µA Regulated Output Voltage: 3.3V ±4%, 5V ±4% 5V Output Current: 50mA (VIN ≥ 3.0V) 3.3V Output Current: 40mA (VIN ≥ 2.5V) No Inductors Needed Very Low Shutdown Current: <1µA Shutdown Disconnects Load from VIN Internal Oscillator: 600kHz Short-Circuit and Overtemperature Protected Ultrasmall Application Circuit: (0.052 Inch2) 6-Pin SOT-23 Package 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 VIN and VOUT) 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 ModeTM switched capacitor voltage doubler to produce a regulated output. It has thermal shutdown capability and can survive a continuous short circuit from VOUT to GND.
