MAX1844ETP+ Overview
The switching controller fits in the 20-WFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 1 output generation. An enclosure of Tube is used to package the PMIC. The program can handle Transistor Driver dc switching's outputs (s). A 4.5V~5.5V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with -40°C~85°C TA. 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. For efficient switching control, the dcdc regulator features Current Limit, Enable, On Time Control, Power Good. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position QUAD . Various 20 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 5V. Other relevant dc to dc converter ics can be found by searching "MAX1844". Pins number 20 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. 4.5V should be the minimum input voltage for the dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 2.5V. Considering the dc to dc regulator can only accept 5.5V input voltage, it is important to take note of this. If you are starting a new project, you should note the dc dc regulator's typical output current is 4A. This Surface Mount makes DC switcher suitable for most prototypes and applications. DC regulators have a maximum frequency of 600kHz. DC to DC voltage regulator has a value of CAN ALSO OPERATE IN PFM MODE to better satisfy the need.
