LM1770UMFX/NOPB Product Details
LM1770UMFX/NOPB Overview
Capsuled in the SC-74A, SOT-753 package, the switching controller can be used for a wide range of applications. PMIC packaging is solid with a Tape & Reel (TR) enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 2.8V~5.5V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 100kHz~1MHz. A generalization of dc dc regulator can be made using Surface Mount. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 5 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 3.3V. You can find other relevant dc to dc converter ics by searching "LM1770". Pins number 5 of switching converter in total. An input voltage of 2.8V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 4.5V voltage. In most cases, the dc dc regulator's output current is 4A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 95 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. It is estimated that this dc regulatorhas a maximum frequency of 1MHz. The value of DC to DC voltage regulator is set at ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V in order to fulfill the requirements more effectively. Users should apply 5.5V to operate the voltage regulator dc to dc safely and reliably. A dc switching in a dormant state uses 400μA. The phase of this controller is 1.
