UCC2897PW Overview

Capsuled in the 20-TSSOP (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 1 input. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 8.5V~14.5V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~105°C TA. Using this switching controller, it is possible to switch at 250kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, On Time Control, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "UCC2897". Pins number 20 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 900mV voltage. In most cases, the dc dc regulator's output current is 2.5A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 74 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controller operates at 1MHz Hz. The value of DC to DC voltage regulator is set at CAN ALSO BE CONFIGURED IN CURRENT MODE in order to fulfill the requirements more effectively. Users should apply 12V to operate the voltage regulator dc to dc safely and reliably. A dc switching in a dormant state uses 2mA. It is possible to set the input voltage as 120V for nominal working statuses. Switching controller is necessary to provide a voltage of 12V. There should be 3mA current exceeding 3mA supplied to the controller.
