UC3845BD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Suitable for a 0°C~70°C TA dc switcher. This switching controller can switch at 500kHz. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. DC regulator outputs 5.1V voltage based on test statistics. The dc to dc regulator can only accept a maximum input voltage of 25V. If you start a project, note down the dc dc regulator's usual output current of 1A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 48 %. Switching controller operates at 275kHz Hz. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. During dormancy, the dc switching uses 12mA.
