the fp6730 is a current-mode, pulse-width modulation, step-up dc/dc converter. the built-in high voltage n-channel mosfet allows fp6730 for step-up applications with up to 24v output voltage, as well as for single ended primary inductance converter (sepic).
the high switching frequency (1mhz) allows the use of small external components. the soft-start function is programmable with an external capacitor, which sets the input current ramp rate. another internal soft-start for sot-23-5 package.
the fp6730 is available in space-saving sot-23-5, sot-23-6 and tdfn-6 (2mm×2mm) packages.
