UC3825NG4 Overview
The switching controller fits in the 16-DIP (0.300, 7.62mm) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 2 numbers. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) are supported. 8.4V~30V is the operating voltage and supply voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. With this switching controller, you can switch at 340kHz~460kHz. The Through Hole makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 16 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC3825". There are only 16 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. An input voltage of 8.8V is the minimum required for the dc dc voltage regulator. Statistically, the DC regulator outputs 13V voltage. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. The maximum duty cycle of this voltage regulator dc to dc is set to 85 % to ensure reliability during power-up and power-down. Switching controller operates at 1MHz Hz. The value of DC to DC voltage regulator is set to CAN ALSO BE CONFIGURED IN CURRENT MODE in order to better satisfy the requirement. Voltage 15V is required for supply. There should be 33mA current exceeding 33mA supplied to the controller.
