LM3743MMX-300 Overview

It comes in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 3V~5.5V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. Switching can be done at 300kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Current Limit, Enable, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . A variety of terminations with 10 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 3.3V. LM3743 can be searched for other relevant dc to dc converter ics. There are a total of 10 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. The minimum input voltage of the dc dc voltage regulator should be 3V. Based on the test statistics, DC regulator outputs voltage 4.6V. It should be noted that the dc to dc regulator only accepts 5.5V voltage as input voltage. You should note that the dc dc regulator's usual output current is 20A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 91 %. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulators have a maximum frequency of 345kHz. When the dc switching is dormant, it uses 1.8mA.
