The LT1614IS8#PBF: The Cuk topology uses a series capacitor to transfer energy, giving continuous input and output current waveforms. Output is adjustable from -1.24 V down to -24 V via an external resistor divider. No synchronous rectifier is used.
The internal switch is rated for 750 mA. The actual output current depends on input voltage, output voltage, and inductor selection, but 750 mA is the maximum switch current the part can handle.
No. The LT1614 is configured for a negative output only. The output is adjustable from -1.24 V down to -24 V. For a positive output, consider the LT1307CS8#PBF boost regulator.
