LM3743MMX-1000 Overview
As a result of 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) can be handled by it. 3V~5.5V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller is capable of switching at the 300kHz position. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Various 10 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 3.3V. A search for "LM3743" will reveal other relevant dc to dc converter ics. There are 10 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. An input voltage of 3V is the minimum required for the dc dc voltage regulator. A 4.6V voltage of DC regulator was detected in the test statistics. It should be fully noted that the dc to dc regulator only accepts 5.5V input voltage at most. You should note down the dc dc regulator's usual output current of 20A when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 76 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulator1.15MHz has the maximum frequency. DC switchings that are dormant use 1.8mA.
