LM1770UMF/NOPB Overview
Capsuled in the SC-74A, SOT-753 package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 2.8V~5.5V volts and has 2.8V~5.5V supply voltage. Suitable for working in an dc switcher that has a -40°C~125°C TJ. This switching controller can switch at 100kHz~1MHz. A generalization of dc dc regulator can be made using Surface Mount. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . The 5 terminations can be used for a wide range of dc switching. 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. In addition to "LM1770", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 5 pins. Input voltage of dc dc voltage regulator should be 2.8V. As determined by the test statistics, the output voltage of DC regulator is 4.5V. You should note that the dc dc regulator's usual output current is 4A. 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. There is a maximum frequency of 1MHz for this dc regulators. DC to DC voltage regulator has a value of ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V to better satisfy the need. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 5.5V. During dormancy, the dc switching uses 400μA.
