LM5642MHX/NOPB Overview
Capsuled in the 28-PowerTSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. 4.5V~36V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. Switching can be done at 200kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Current Limit, Enable, Soft Start is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 28 of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. Other relevant dc to dc converter ics will be returned if you search "LM5642". Switching converter has a total of 28 pins. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. DC regulator outputs 32.4V voltage based on test statistics. A maximum voltage of 36V is accepted by the dc to dc regulator as an 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. 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 226kHz. During dormancy, the dc switching uses 1.1mA.
