Working Principle:

The HIP6013CBZ-T is a non-synchronous buck regulator that uses a current-sensing algorithm for the power conversion. The power conversion process starts by sampling the output voltage through an internal voltage divider. The voltage divider is then monitored by an internal voltage monitoring window comparator. When the output voltage falls below the programmed output voltage, the internal MOSFET switches from the low side to the high side, thereby initiating the power conversion process. Then the proportion of duty cycle is controlled by the current-sensing algorithm. The current-sensing algorithm utilizes the output inductor current to regulate the output voltage, allowing the device to deliver stable voltage across a wide range of load conditions.

The device also includes a number of safety functions such as over-voltage protection, cycle-by-cycle current limit, soft-start, and output short-circuit protection. These features maximize the device\'s overall system stability and reliability.

In summary, the HIP6013CBZ-T is an ultra-low power, high-accuracy, and non-synchronous buck regulator ideal for applications ranging from notebook computers and mobile devices to industrial systems. With its wide input voltage range and low quiescent current, it is perfect for today\'s power-saving products. The current-sensing feedback control loop helps to ensure reliable performance with minimal output noise across a wide range of loads.
