LM1770SMF/NOPB Overview
With a SC-74A, SOT-753 package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). 2.8V~5.5V is the operating voltage and supply voltage of the dc control. A -40°C~125°C TJ dc switcher is not a problem. The switching controller can be switched at 100kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 5 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 3.3V. Searching "LM1770" will return other relevant dc to dc converter ics. There are a total of 5 pins on switching converter. This dc dc voltage regulator should be powered by a voltage of 2.8V. The test statistics indicate that DC regulator outputs a voltage of 4.5V. The dc dc regulator's usual output current is 4A, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 95 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. 1MHz is the maximum frequency of this dc regulators. DC to DC voltage regulator has the value of ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V to better satisfy the requirement. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 5.5V. In dormant mode, 400μA is used.
