LM1770SMFX/NOPB Product Details

LM1770SMFX/NOPB Overview


In the SC-74A, SOT-753 package, the switching controller meets most application requirements. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 2.8V~5.5V. Worked in an dc switcher with a -40°C~125°C TJ rating. There is a switch at 100kHz~1MHz that can be used with this controller. dc dc regulators can be carried out with Surface Mount. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 5 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 3.3V volts. You can find other relevant dc to dc converter ics by searching "LM1770". Total pins of switching converter are 5. In particular, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 2.8V. Based on the test statistics, DC regulator outputs voltage 4.5V. The dc dc regulator's usual output current is 4A, which should be noted down when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 95 % on power-up or power-down to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator1MHz has the maximum frequency. 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. A circuit should contain 5.5V in order to ensure the voltage regulator dc to dc runs safely and reliably. A dc switching in a dormant state uses 400μA. Phases of this controller are 1.
