Description
UC1843AMDREP Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 7.6V~30V. Qualified to work in a -55°C~125°C TA dc switcher. It can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . An array of 8 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC1843". 8 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. The test statistics indicate that DC regulator outputs a voltage of 13.5V. If you start a project, note down the dc dc regulator's usual output current of 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. 500kHz is the frequency of the switching controller. The maximum input voltage of the dc switcher is 25V, so users need to limit the voltage accordingly. DC switcher will not be able to provide an output current above 200mA volts. As per its datasheet, the switching converter has a maximum output of 15V volts. The switching converter could be operated with an input of 11mA current flow.
