CA02COME36-5SBF80 Application Field and Working Principle

The CA02COME36-5SBF80 is a surface-mounted, microcontroller-based, ultra-low power, multi-channel switching regulator with an integrated module. It is used to provide an adjustable voltage output from a wide range of supply voltages. Primarily used for powering small devices in battery-operated or other applications requiring extreme low power and cost efficiency, this switch regulator is especially designed for points-of-sale (POS) terminals, mobile medical devices, hand-held testing instruments, sensors, and other portable electronic components.

Design and Construction

The CA02COME36-5SBF80 is a surface-mounted device made of a system-on-chip (SOC) with a switching regulator, power management unit, and an adjustable voltage regulator. The built-in SOC is responsible for sensing and controlling the output voltage, while the SRCF does the actual switching and regulates the voltage. The adjustable voltage regulator is used to adjust the voltage output from the system.This switch regulator is designed to provide a reliable and low power operation. It utilizes an integrated, low-power switching regulator in combination with an adjustable voltage regulator to enable high efficiency in a compact package. The device features an extremely small form factor, excellent ESD protection and thermal efficiency. It is also capable of operating on a wide supply voltage range (from 0.9V to 6V) and can deliver an adjustable output voltage up to a maximum of 2.5V.

Working Principle

The CA02COME36-5SBF80 operating principle involves the use of an integrated, low power switching regulator to convert the main supply voltage into a lower, adjustable voltage to power the connected load. The internal switching regulator consists of four main components – an inductor, a diode, a capacitor and a switch. When the chip\'s on/off signal is positive, current passes through the inductor and charges up the capacitor. Afterward, the switch will turn off, and the current stored in the inductor will flow towards the output. The diode acts as a path for the current in the reverse direction and prevents it from flowing back.In addition, the adjustable voltage regulator contained within the chip is used to adjust the output voltage of the circuit. This regulator includes a voltage reference, an error amplifier, and a bandgap voltage. The reference voltage is compared with the output voltage, and the error amplifier generates an output voltage value which is used to control the switching element, thereby regulating the output voltage.The adjustable voltage output and high efficiency of this switch regulator make it suitable for powering various portable and battery-operated electronic devices. It is also an excellent choice for low cost and low power applications.

Conclusion

The CA02COME36-5SBF80 is an integrated, microcontroller-based, multi-channel switching regulator with an adjustable voltage output. This allows for efficient and cost-effective operation, and the wide supply voltage range and adjustable output voltage make it an ideal choice for applications requiring a reliable and low power source. The integrated switching regulator and adjustable voltage regulator provide excellent performance in a compact package.
