Product Summary
The LTC1514IS8-3.3#TR is a micropower switched capacitor DC/DC converter that produces a regulated output voltage by either stepping up or stepping down the input voltage. Output voltage is fixed at either 3.3V (LTC1514-3.3) or 5V (LTC1514-5) by an internal resistor divider. A unique architecture allows the parts to accommodate a wide input voltage range (2V to 10V) while maintaining ±4% regulation. Additional circuitry prevents excessive inrush current and output voltage ripple when large VIN to VOUT differentials are present. The applications of the LTC1514IS8-3.3#TR include Battery-Operated Equipment, Smart Card Readers, Local Power Supplies, Handheld Instruments, Battery Backup Supplies.
