UCC3803PWG4 Overview
The switching controller fits in the 8-TSSOP (0.173, 4.40mm Width) package and is ideal for most applications. 1 outputs can be generated with the dc motor controller. There is a Tray solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 3.6V~12V. Worked in an dc switcher with a 0°C~70°C TA rating. It can switch at 31kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 10V. Other relevant dc to dc converter ics can be found by searching "UCC3803". There are 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4V. Statistically, DC regulator outputs 1V volts. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. There is 1MHz frequency setting on the switching controller.
