UC3842BVDR2 Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 10V~30V. Qualified to work in an dc switcher with -40°C~105°C TA. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. DUAL are the position of the terminal of the switching converters. A variety of 14 terminations are available in dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. In total, switching converter has 8 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. Voltages 25V are the maximum that the dc to dc regulator will accept. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 96 %. Switching controllers operate at 60kHz frequencies. When the dc switching is dormant, it uses 12mA.
