DESCRIPTION
The LTC®1514-3.
3/LTC1514-5 are micropower switched capacitor DC/DC converters that produce 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.
