LM1771UMM/NOPB Overview
Capsuled in the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, the switching controller can be used for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. An enclosure of Tape & Reel (TR) is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 2.8V~5.5V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. The switching controller is capable of switching at the 100kHz~1MHz position. dc dc regulators can be carried out with Surface Mount. Switching control is made easier with the dcdc regulator's Enable. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 8 of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 3.3V. A search for "LM1771" will reveal other relevant dc to dc converter ics. Pins number 8 of switching converter in total. As determined by the test statistics, the output voltage of DC regulator is 4.5V. In most cases, the output current of the dc dc regulator will be 6A, so note that when you start the project. It is set to 95 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. DC regulator has a maximum frequency of 1MHz. To operate the voltage regulator dc to dc safely and reliably, users should apply 5.5V. Dormant dc switchings use 400μA.
