MAX1897ETP+T Overview
Capsuled in the 20-WQFN Exposed Pad package, the switching controller can be used for a wide range of applications. 1 outputs are supported by the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 4.5V~5.5V voltage are supplied and operated. Worked in a -40°C~85°C TA dc switcher before. This switching controller can switch at 200kHz 300kHz 550kHz. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, On Time Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . An array of 20 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 5V. In addition to "MAX1897", there are other relevant dc to dc converter ics you can find. Pins number 20 of switching converter in total. Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. A maximum voltage of 5.5V is accepted by the dc to dc regulator as an input voltage. This dc regulatorhas a max frequency of 550kHz. For better satisfaction, the value of DC to DC voltage regulator is ALSO REQUIRES A BATTERY VOLTAGE OF 4V TO 28V. It belongs to the dc to dc voltage regulator series Quick-PWM?.
