Working Principle

The XC9265B1214R-G operates as a DC-DC switching regulator, controlling the output voltage by switching between two voltage levels. It has an integrated control circuit, allowing it to operate in either pulse width modulation (PWM) or discontinuous mode. In PWM mode, the control circuit modulates the duty cycle of the output voltage, maintaining a constant voltage output even when the input voltage fluctuates significantly. In discontinuous mode, the control circuit senses the input voltage and adjusts the output voltage in response.

When operating in PWM mode, the XC9265B1214R-G utilizes a high-frequency pulse-width modulation technique, which drastically reduces switching losses and improves the regulator’s efficiency. The switching frequency can be adjusted from 500 KHz to 1.5MHz, allowing the user to optimize the switching speeds and output voltage for their specific application. The regulator also features a built-in soft-start function, which reduces inrush current at turn-on, minimizing the stress on other components in the system.
