MAX1844ETP+ Overview
This switching controller fits most application requirements since it is packaged in a 20-WFQFN Exposed Pad package. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 4.5V~5.5V are the dc control's supply voltage and operating voltage, respectively. Suitable for 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 . dc dc regulator is made easier with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, On Time Control, Power Good. SWITCHING CONTROLLER analog IC connects the switch converters. QUAD are the position of the terminal of the switching converters. A variety of terminations with 20 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 5V. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. It should be fully noted that the dc to dc regulator only accepts 5.5V input voltage at most. To better satisfy the need, DC to DC voltage regulator has a value of CAN ALSO OPERATE IN PFM MODE.
