LM25117PMHE/NOPB Overview


This switching controller fits most application requirements since it is packaged in a 20-PowerTSSOP (0.173, 4.40mm Width) package. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4.5V~42V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. In this switching controller, the switch can be set to Up to 750kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control, Ramp, Soft Start. An analog IC SWITCHING CONTROLLER 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. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 24V. You can find other relevant dc to dc converter ics by searching "LM25117". There are a total of 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 800mV. The dc to dc regulator is limited to 42V input voltage. You should note that the dc dc regulator's usual output current is 3.3A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulator750kHz has the maximum frequency. DC switching uses 4.8mA when it is dormant.
