Fixed 1MHz PWMoperation allows possible smallest output ripple andexternal component size. With high conversion efficiencyand small package, the uP6305 is ideally suitable forportable devices and USB/PCIE-based interface cardswhere PCB area is especially concerned.With internal low RDS(ON) switches, the uP6305 is capableof delivering 2.0A output current over a wide input voltagerange from 2.5V to 5.5V. The output voltage is adjustablefrom 0.6V to VIN by a voltage divider. Other features includeinternal soft-start, chip enable, overvoltage, under-voltage,over-temperature and over-current protections. The uP6305is available in a space-saving WQFN3x3-16L,WLCSP1.5x1.5-9B or PSOP-8L packages.Battery-Powered Portable DevicesMP3 PlayersDigital Still CamerasWireless and DSL ModemsPersonal Information Appliances802.11 WLAN Power SuppliesFPGA/ASIC Power SuppliesDynamically Adjustable Power Supply forCDMA/WCSMA Power AmplifiersUSB-Based xDSL Modems and Other NetworkInterface CardsPoint-of-Load RegulationGeneral DescriptionApplicationsOrdering InformationFeaturesLXFBPOKPGNDNCENAGNDGND12345678PSOP - 8VINPGNDAGNDFBVINNCVCCPGNDENPGNDLXPOKPGNDNCVINVINLXLX123AGNDWLCSP1.5x1.5-9B GNDFBNC LX LXEN VIN VINBC12348765121110913151516WQFN3x3-16L Note: uPI products are compatible with the current IPC/JEDEC J-STD-020 requirement.
