UC3842ADM Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For 1 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). 10V~30V is the supply voltage and the operating voltage of the dc control. A 0°C~70°C TA dc switcher is not a problem. The switching controller is capable of switching at the Up to 500kHz position. A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "UC*84". 8 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 5V. A maximum voltage of 30V is accepted by the dc to dc regulator as an input voltage. You should note that the dc dc regulator's usual output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. Switching controllers operate at 500kHz frequencies. In dormant mode, 11mA is used. The supply current of the voltage controller is 11mA.
