LM25119PSQ/NOPB Overview

In the 32-WFQFN Exposed Pad package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 4.5V~42V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. It can switch at 50kHz~750kHz. The Surface Mount value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Ramp, Reset, Soft Start. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . The 32 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "LM25119". There are 32 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. 4.5V should be the minimum input voltage for the dc dc voltage regulator. Statistically, the DC regulator outputs 15V 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. A duty cycle set at 95 % ensures voltage regulator dc to dc reliability during power-on and power-off. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. There is a maximum frequency of 530kHz for this dc regulators. This value is PROGRAMMABLE OUTPUT FROM 0.8 V so that DC to DC voltage regulator better serves the purpose. In a dormant state, the dc switching uses 6mA. Voltage 36V is required for supply. There should be 7.3mA current exceeding 7.3mA supplied to the controller.
