LM5642XMHX/NOPB Overview


With its 28-PowerTSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. PMIC packaging is solid with a Tape & Reel (TR) enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 4.5V~36V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~125°C TJ dc switcher. The switching controller is capable of switching at the 375kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 28 terminations are available in dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. Searching "LM5642" will return other relevant dc to dc converter ics. Switching converter has a total of 28 pins. The minimum input voltage of the dc dc voltage regulator should be 4.5V. Test statistics indicate DC regulator outputs 32.4V voltage. Voltages 36V are the maximum that the dc to dc regulator will accept. In most cases, the dc dc regulator's output current is 20A. This information should be noted when you begin working with the component. voltage regulator dc to dcs with a 98.9 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. The max frequency of the pmic can reach 424kHz. Dormant dc switchings use 1.1mA.
