XC9303B093KR-G application field and working principle
PMIC (power Management IC) is a type of semiconductor component typically used for system power management, like voltage converters, power regulators, current monitors, or system thermal management. Voltage Regulators and DC DC Switching Controllers are two categories of PMICs, and XC9303B093KR-G is a part of them.
Application Field of XC9303B093KR-G
XC9303B093KR-G is a DC-DC step-down synchronous power switch with a high efficiency MOSFET and integrated controller, targeted for applications with up to 40V input voltage, up to 13A output current and up to 36V output voltage. It is suitable for use in phones, consumer electronics, and automotive applications.The XC9303B093KR-G features an adjustable buck controller with a wide input voltage range of 3V to 40V, an adjustable duty cycle of 0.6V to 1.0V, and a feedback voltage of 0.600V. It has a maximum operating frequency of 1MHz, and contains an integrated power switch, overvoltage protection, and current limit protection.
Working Principle of XC9303B093KR-G
The XC9303B093KR-G is a DC-DC step-down synchronous power switch with a high efficiency MOSFET and integrated controller. It operates on a constant frequency pulse width modulation principle. The power switch of XC9303B093KR-G consists of three major components, namely the controller, inductor, and MOSFET. The operation begins by a start signal from the controller to turn the MOSFET ON. There is a high-side current sense resistor to sense the current from the Vout node to the ground. The controller then compares the voltage at the inductor to a reference voltage, which is usually a 0.6V reference voltage. The reference voltage determines the duty cycle and thus the output voltage. The duty cycle is basically determined as the ratio between the voltage in inductor and the reference voltage. The higher the reference voltage, the lower the output voltage, and vice versa. The controller then turns the MOSFET OFF in order to store the energy collected by the inductor. The energy stored in the inductor is then discharged through the MOSFET to the load. The cycle repeats itself until the controller stops the operation.
Therefore, XC9303B093KR-G is an effective DC-DC step-down synchronous power switch with a high efficiency MOSFET and integrated controller which is suitable for use in phones, consumer electronics, and automotive applications.
