Working Principle

The ISL6545ACBZ-TS2698 works by regulating the output voltage to ensure a stable output voltage regardless of load current. The switching controller monitors the voltage across its output and adjusts the duty cycle of the high side and low side MOSFETs accordingly. This results in a regulated output voltage that remains constant regardless of the load.

The ISL6545ACBZ-TS2698 also has a peak current limit feature that prevents over current conditions from occurring. When the current limit is exceeded, the controller will reduce the duty cycle of the MOSFETs until it reaches the current limit again. This prevents the system from becoming unstable or damaged due to overcurrent conditions.

The controller includes an integrated soft start circuit as well. This is important for applications where inrush current must be kept to a minimum. When enabled, the controller will gradually increase the duty cycle of the MOSFETs until the output voltage reaches its desired set-point. This prevents large inrush currents from occurring, which can damage components or cause the system to become unstable. Additionally, the controller is programmable through either a serial or I2C interface depending on the configuration.
