LM1770TMF/NOPB Product Details
LM1770TMF/NOPB Overview
It comes in a SC-74A, SOT-753 package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 2.8V~5.5V voltage are supplied and operated. A -40°C~125°C TJ dc switcher is not a problem. A switching controller such as this can switch at a value of 100kHz~1MHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . A variety of 5 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 3.3V volts. LM1770 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 5 pins. 2.8V should be the minimum input voltage for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 4.5V. You should note down the dc dc regulator's usual output current of 4A when you start a project. A duty cycle set at 95 % ensures voltage regulator dc to dc reliability during power-on and power-off. This Surface Mount makes DC switcher suitable for most prototypes and applications. This dc regulatorhas a max frequency of 1MHz. As a result, DC to DC voltage regulator has a value of ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V so that the need can be met more directly. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 5.5V. DC switchings that are dormant use 400μA.
