MAX1844EEP+ Overview


With its 20-SSOP (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 4.5V~5.5V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~85°C TA dc switcher. With this switching controller, you can switch at 200kHz 300kHz 450kHz 600kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, On Time Control, Power Good is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. 20 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "MAX1844". Total pins of switching converter are 20. Switching converter type is specifically Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. A 2.5V voltage of DC regulator was detected in the test statistics. Considering the dc to dc regulator can only accept 5.5V input voltage, it is important to take note of this. It's important to remember that the dc dc regulator's normaloutput current is 4A, so you should note it down when starting a new project. There is a maximum frequency of 600kHz for this dc regulators. DC to DC voltage regulator has a value of CAN ALSO OPERATE IN PFM MODE to better satisfy the need.
