LM1770TMFX/NOPB Product Details

LM1770TMFX/NOPB Overview


In the SC-74A, SOT-753 package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. 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. A -40°C~125°C TJ dc switcher is not a problem. With this switching controller, you can switch at 100kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a DUAL terminal on the switching converters. There are many different types of terminations for 5. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 3.3V. LM1770 can be searched for other relevant dc to dc converter ics. 5 pins are on switching converter. Input voltage of dc dc voltage regulator must be 2.8V. The test statistics indicate that DC regulator outputs a voltage of 4.5V. You should note that the dc dc regulator's usual output current is 4A. It is set to 95 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. This Surface Mount makes DC switcher suitable for most prototypes and applications. It is estimated that this dc regulatorhas a maximum frequency of 1MHz. This value is ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V so that DC to DC voltage regulator better serves the purpose. 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.
