LM5121MH/NOPB Overview


With its 20-PowerTSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. dc motor controller is suitable for 1 output generation. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 4.5V~65V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~125°C TJ. Using this switching controller, it is possible to switch at Up to 1MHz. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 20 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 12V is input. Search for "LM5121" to find other relevant dc to dc converter ics. There are only 20 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. 4.5V should be the minimum input voltage for the dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 100V. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 100 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sIf the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 65V. The dc switching utilizes 4mA when it is in a dormant state.
