UCC2897RTJR Overview


In the 20-WFQFN Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 1 output generation. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 8.5V~14.5V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~105°C TA dc switcher. There is a switch at 250kHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. Enable, On Time Control, Soft Start provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. There are many different types of terminations for 20. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. A search for "UCC2897" will reveal other relevant dc to dc converter ics. There are 20 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 900mV voltage. You should note that the dc dc regulator's usual output current is 2A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 74 %. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controller operates at 1MHz Hz. As a result, DC to DC voltage regulator has a value of CAN ALSO BE CONFIGURED IN CURRENT MODE so that the need can be met more directly. A circuit should contain 12V in order to ensure the voltage regulator dc to dc runs safely and reliably. Input voltage can be set to 120V for nominal working status.
