UCC2897PWR Overview
Capsuled in the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller suits most application needs. 1 outputs can be generated with the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 8.5V~14.5V and has a 8.5V~14.5V supply voltage. Suitable for working in an dc switcher that has a -40°C~105°C TA. Using this switching controller, it is possible to switch at 250kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Enable, On Time Control, Soft Start for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Various 20 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "UCC2897". The switching converter has a total of 20 pins. The type is a particular Switching Regulator or Controllers of switching converter. As determined by the test statistics, the output voltage of DC regulator is 900mV. If you are starting a new project, you should note the dc dc regulator's typical output current is 2A. The duty cycle of the voltage regulator dc to dc can be set to 74 % on power-up or power-down to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. A frequency of 1MHz is set for the switching controller. The value of DC to DC voltage regulator is set to CAN ALSO BE CONFIGURED IN CURRENT MODE in order to better satisfy the requirement. To run the voltage regulator dc to dc safely and reliably, users should apply 12V to the voltage regulator dc to dc. Input voltage can be set to 120V for nominal working status. Voltage 12V is required for supply. The controller should not be supplied with more current than 3mA.
