Product Details
The LTC1754 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 Mode™ 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.
The LTC1754 is available in a 6-pin SOT-23 package.
Applications
- SIM Interface Supplies for GSM Cellular Telephones
- White LED Power Supplies
- Li-Ion Battery Backup Supplies
- Handheld Computers
- Smart Card Readers
- PCMCIA Local 5V Supplies
