MAX1844EEP+ Overview
It comes in the 20-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 4.5V~5.5V voltage are supplied and operated. Work well in dc switchers with a -40°C~85°C TA. Switching can be done at 200kHz 300kHz 450kHz 600kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, On Time Control, Power Good. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. Various 20 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 5V. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator can only accept a maximum input voltage of 5.5V. In order to satisfy the need, DC to DC voltage regulator has a value of CAN ALSO OPERATE IN PFM MODE.
