Working Principle

BCM47063SO01 works through a buck-boost winding. The primary winding receives a constant voltage and passes it to the secondary winding, which is also connected to the output voltage. When there is an input voltage above the output voltage, the output voltage is regulated through the buck-boost winding. In addition, the output voltage can be regulated using an external resistor. By adjusting this resistor, the output current can be regulated accordingly. Moreover, the output voltage can be protected by the OVP feature which turns off the internal MOSFET when the input voltage exceeds the maximum rating set by the OVP circuitry.

BCM47063SO01 also includes a shutdown control feature, which allows the device to enter a low power state and reduce power consumption when the input voltage goes below the device’s minimum operating voltage. In addition, the device includes a thermal protection function which automatically reduces the output voltage and current when the temperature of the device exceeds a safe operating temperature.

Additionally, the device supports soft-start feature which enables it to gradually increase the output voltage as the temperature increases. This helps to reduce the output inrush current during the start-up and also avoids potential system crashes by providing a means to monitor the output voltage.

Overall, BCM47063SO01 is a highly efficient, reliable, and safe device suitable for a wide range of applications, and offers features such as overvoltage protection, shutdown control, thermal protection, and soft-start to ensure safe and reliable voltage regulation.
