Working Principle of ADP2108ACBZ-1.2-R7 DC DC Switching Regulators

The ADP2108ACBZ-1.2-R7 DC DC switching regulator operates on the principle of a continuous conduction mode (CCM) pulse width modulated (PWM) buck converter. The output voltage is determined by the ratio of the on and off switching period. During the on period, a relatively low amount of current is drawn through the input on the converter and is stored in an inductor. At the end of this period, a switch is opened which discharges the inductor into the output capacitor, while the voltage across the inductor is multiplied as it is discharged. This combination of inductor and capacitor provides the necessary filtering to reduce the output ripple and minimize EMI. Furthermore, the switching frequency is controlled by an internal circuit that monitors the output voltage and adjusts the switching frequency accordingly, resulting in superior transient performance.

The ADP2108ACBZ-1.2-R7 DC DC switching regulators feature a pre-charge current ramp rate control that allows the user to increase the current into the output capacitor slowly, avoiding inrush current spikes. It also includes a soft-start function that ramps up the output voltage slowly over time to reduce output capacitor stress. In addition, the device incorporates a low-voltage dropout feature for improved efficiency, together with a low-dropout voltage that is among the lowest in the industry. All these features make the ADP2108ACBZ-1.2-R7 DC DC switching regulator an excellent choice for automotive, telecom, and industrial applications.
