Microchip (MCP1253-33X50I/MS) DC/DC Fixed Charge Pump Voltage Converter

DC/DC Fixed Charge Pump Voltage Converter, 2 V to 5.5 V in, 3.3 V/150 mA out,MSOP-8Product OverviewThe MCP1253-33X50I/MS is an inductor less, positive-regulated charge pump DC/DCConverter. The devices generate a regulated fixed (3.3 or 5.0V) or adjustableoutput voltage. They are specifically designed for applications requiring lownoise and high efficiency and are able to deliver up to 120mA output current.The devices allow the input voltage to be lower or higher than the outputvoltage, by automatically switching between buck/boost operation. These chargepumps operate at a switching frequency of 1MHz (reducing capacitor sizes) andfeature power saving shutdown pins, short-circuit protection, thermal shutdownand power-good pins that report out-of-regulation conditions.Low 60 µA supply current in no load conditionsHigh 2.5% voltage accuracy (on fixed voltage outputs)High 1MHz operation to avoid interference with IF bandsAllows for small capacitor use to save board space and costLogic level shutdown control reduces current consumption to 0.1µA during standbyoperationPower-good output indicator with hysteresisThermal shutdown protection with hysteresisShort-circuit protectionSoft-start circuitry to minimize inrush currentApplicationsLED Lighting, Consumer Electronics, Computers & Computer Peripherals, AutomotiveProduct InformationOutput Type: FixedInput Voltage Min: 2VInput Voltage Max: 5.5VDC / DC Converter IC Case: MSOPNo. of Pins: 8PinsOutput Current: 150mAFixed Output Voltage Nom: 3.3VTopology: Buck, BoostOperating Temperature Max: 85°CAutomotive Qualification Standard: AEC-Q100MSL: MSL 1 - Unlimited
