FAN48623UC33X Integrated Circuits (ICs)

PMIC - Voltage Regulators - DC DC Switching Regulators

The FAN48623UC33X is a lightweight, fanless non-isolated DC/DC buck regulator module with wide input and adjustable output voltage range. Based on a monolithic integrated circuit, it provides a total power conversion of up to 8.5Amps at an output voltage of 3.3V. It includes an integrated over-temperature and over-current protection feature and is suitable for industrial grade applications.

Working Principle

In its simplest form, the FAN48623UC33X can be compared to an up and down converter, effectively changing a low voltage from the input supply to a higher voltage on the output side. This is achieved by using MOSFETs and a continuous duty cycle, which means that the duty cycle of the switching converter remains constant. A buck converter is basically an electronic switch and a low-pass filter working together.

At the start of the buck cycle, the output voltage is low and the high side MOSFET turns on. It connects the input voltage to the output side and allows the input voltage to flow to the output side. This current is filtered by a low-pass filter. Then the high side MOSFET turns off and the low side turns on, which takes the current from the output side to ground. This is repeated in a continuous loop, resulting in an output voltage that is higher than the input voltage.

Applications

The FAN48623UC33X is used primarily in industrial grade applications that require a high-efficiency power solution. It can be used in a variety of applications including robotics, lighting control, camera systems, micro-controllers, automation systems, and medical equipment.
