UC3845BD1R2 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs are supported by the dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. The switching controller can be switched at 500kHz. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . A variety of 8 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Search for "UC384*B" to find other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 5.1V volts. The dc to dc regulator can only accept 25V input voltage. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. There is a maximum frequency of 275kHz on this dc regulators. To operate the voltage regulator dc to dc safely and reliably, users should apply 30V.
