UC3842AD8TR Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With Transistor Driver dc switching's output (s), it is able to handle it. A 10V~30V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with 0°C~70°C TA. It can switch at Up to 500kHz. dc dc regulator is made easier with Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at DUAL. 8 terminations with a variety of function. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. UC3842 can be searched for other relevant dc to dc converter ics. 8 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 15V voltage. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. Switching controllers work at 450kHz Hz. It is possible to set the input voltage to 25V for nominal working status. The supply voltage must be 11V. In order to ensure proper operation, the controller should not receive more current than 25mA.
