E-UC3843BD1 Product Details
E-UC3843BD1 Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Suitable for working in an dc switcher that has a 0°C~70°C TA. The switching controller can be switched at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. UC3843 can be searched for other relevant dc to dc converter ics. 8 pins are on switching converter. Based on the test statistics, DC regulator outputs voltage 5.1V. At most, the dc to dc regulator accepts 30V input voltage. You should note down the dc dc regulator's usual output current of 1A 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 100 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at 250kHz Hz.
