The switching controller fits in the SC-74A, SOT-753 package and is ideal for most applications. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 2.5V~16V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~85°C TA. A switching controller such as this can switch at a value of 180kHz . dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Enable which allows efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 5 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 2.5V is input. It is recommended that the input voltage of the dc dc voltage regulator be 2.5V. Test statistics indicate DC regulator outputs 1.8V voltage. As a result, DC to DC voltage regulator has a value of ALSO OPERATES AS PFM so that the need can be met more directly. As a result, switching converter	 outputs current to the greatest value possible (0.05A).
