Working Principles

The ISL6613BEIBZ-T is a power management IC that utilizes a buck converter topology to efficiently convert an input voltage to a regulated output voltage. It incorporates high-side and low-side MOSFET drivers, which control the switching of an external inductor connected to the LX pin. The feedback pin (FB) allows the output voltage to be regulated by adjusting the duty cycle of the switching waveform.

During operation, the IC monitors the output voltage and adjusts the duty cycle accordingly to maintain the desired voltage level. It also provides overcurrent protection by monitoring the current flowing through the external inductor and shutting down the system if the current exceeds a set threshold. Additionally, the IC includes thermal shutdown protection to prevent damage due to excessive heat.
