Working Principle

The LT8301IS5#TRMPBF is a synchronous step-down current mode converter designed for high efficiency from a wide input range at up to 12A of output current. It works by using a switching regulator that takes in a higher input voltage and produces a lower output voltage. The voltage regulation is achieved by the feedback loop inside the chip comparing the output voltage to the reference voltage. When an error is detected, the error signal is used to adjust the switching regulator so that the output voltage is maintained at the desired level.

When the LT8301IS5#TRMPBF is operating in the continuous conduction mode (CCM), the output inductor peak current is limited to the range defined by the current sense resistor in order to prevent inductor saturation. Once the inductor current reaches the peak current limit, it will turn off the high side MOSFET switch, decreasing the current until the device reaches the minimum on-time defined by the OVP comparator. The steady state output voltage is then maintained by adjusting the conduction time and peak current of the switches.

The LT8301IS5#TRMPBF also offers adjustable frequency, adjustable current limit, and adjustable over voltage protection which make it ideal for a variety of applications. It is capable of delivering high efficiency across a wide input range, making it perfect for point-of-load applications where low noise and efficiency are essential.
