s s s s s s s s s s s s DESCRIPTIO Input Voltage Range: 2.4V to 6V Fixed Output Voltages: 1.8V ± 4%, 2V ± 4% Output Current: Up to 100mA No Inductors Typical Efficiency 25% Higher than LDOs Low Operating Current: 25µA Low Shutdown Current: 5µA 600kHz Switching Frequency Shutdown Disconnects Load from VIN Soft-Start Limits Inrush Current at Turn-On Short-Circuit and Overtemperature Protected Available in 8-Pin MSOP and SO Packages The LTC®1503-1.8/LTC1503-2 are switched capacitor step-down DC/DC converters that produce a regulated output from a 2.4V to 6V input. The parts use switched capacitor fractional conversion to achieve high efficiency over the entire input range. No inductors are required. Internal circuitry controls the step-down conversion ratio to optimize efficiency as the input voltage and load conditions vary. Typical efficiency is 25% higher than that of a low dropout (LDO) linear regulator. Regulation is achieved by sensing the output voltage and enabling the internal switching network as needed to maintain a fixed output voltage.
