UC3823NG4 Overview
As a result of 16-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 8.4V~30V voltage is supplied to the dc control and used for operating it. Suitable for work in a 0°C~70°C TA dc switcher. It can switch at 340kHz~460kHz. The Through Hole allows it to be used for dc dc regulator in general. The dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Soft Start for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 16 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3823". Switching converter has a total of 16 pins. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5.2V voltage based on test statistics. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. Voltage regulator dc to dc is designed to operate at 85 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 1MHz is set for the switching controller. As a result, DC to DC voltage regulator has a value of CAN ALSO BE CONFIGURED IN CURRENT MODE so that the need can be met more directly. Switching controller is necessary to provide a voltage of 15V. It is not recommended to supply more current to the controller than 33mA. Input of 22mA current flow would satisfy the operation requirements of the switching converter .
