LM5642XMTX Product Details

LM5642XMTX Overview

It comes in a 28-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. The dc motor controller is adquate to generate for 2 outputs. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~36V and has a 4.5V~36V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. A switching controller such as this can switch at a value of 375kHz . dc dc regulator is made easier with Surface Mount. To provide efficient switching control, Current Limit, Enable, Soft Start is included in the dcdc regulator. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. 28 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 5V. LM5642 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 28 pins. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator must be 4.5V. DC regulator outputs 32.4V voltage according to the test statistics. This dc to dc regulator accepts only 36V 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 98.9 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulator has a maximum frequency of 424kHz. When the dc switching is dormant, it uses 1.1mA.
