MAX1844EEP+T Overview


With its 20-SSOP (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 1 outputs. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 4.5V~5.5V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 200kHz 300kHz 450kHz 600kHz . The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Current Limit, Enable, On Time Control, Power Good for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. An array of 20 terminations of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 5V. A search for "MAX1844" will reveal other relevant dc to dc converter ics. In total, switching converter has 20 pins. Switching converter is a type of Switching Regulator or Controllers in particular. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Statistically, the DC regulator outputs 2.5V voltage. It should be noted that the dc to dc regulator only accepts 5.5V voltage as input voltage. In most cases, the output current of the dc dc regulator will be 4A, so note that when you start the project. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulators have a maximum frequency of 600kHz. For better satisfaction, the value of DC to DC voltage regulator is CAN ALSO OPERATE IN PFM MODE.
