UC3845BNG Overview


This switching controller fits most application requirements since it is packaged in a 8-DIP (0.300, 7.62mm) package. There is sufficient capacity to generate switching controller for outputs 1. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). 7.6V~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 can be switched at 500kHz. As it has a Through Hole value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminals (s) are designed at DUAL. 8 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "UC384*B". There are only 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5.1V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note that the dc dc regulator's usual output current is 200mA. 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 %. As DC switcher has a Through Hole, it's suitable for most applications and prototype designs. There is 52kHz frequency setting on the switching controller. Continually operating at more than 17mA may cause malfunctions and damage to the component.
