LM3743MM-1000/NOPB Overview
Capsuled in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, the switching controller suits most application needs. There is a Tape & Reel (TR) solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). dc controls with 3V~5.5V voltage are supplied and operated. Work well in dc switchers with a -40°C~125°C TJ. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 10 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 3.3V is input. Search for "LM3743" to find other relevant dc to dc converter ics. 10 pins are on switching converter. It is recommended to use 3V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 4.6V voltage based on test statistics. The dc to dc regulator is limited to 5.5V input voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. The duty cycle of the voltage regulator dc to dc can be set to 76 % on power-up or power-down to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. 1MHz is the frequency of the switching controller. For better satisfaction, the value of DC to DC voltage regulator is OUTPUT VOLTAGE ADJUSTABLE DOWN TO 0.8V. As long as the dc switching is in a dormant state, it utilizes 1.8mA. With this controller, the phase is 1.
