LM5642MTCX/NOPB Overview
This switching controller fits most application requirements since it is packaged in a 28-TSSOP (0.173, 4.40mm Width) package. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~36V and has a 4.5V~36V supply voltage. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. With this switching controller, you can switch at 200kHz. The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Enable, Soft Start is used for efficient switching control in the dcdc regulator. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 28. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 5V. In addition to "LM5642", there are other relevant dc to dc converter ics you can find. 28 pins are on switching converter. 4.5V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 32.4V voltage according to the test statistics. It should be noted that the dc to dc regulator only accepts 36V voltage as input voltage. In most cases, the dc dc regulator's output current is 20A. This information should be noted when you begin working with the component. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. There is a maximum frequency of 226kHz for this dc regulators. In a dormant state, the dc switching uses 1.1mA.
