The UCC38C45DGK is a DC-DC switching controller with a broad range of applications. As a PMIC (Power Management Integrated Circuit), it offers a versatile solution for controlling the output voltage, current, and power consumption of a variety of devices. It also provides a high-speed switch mode circuit that can range over a wide range of input voltages and output currents.

The UCC38C45DGK is a fully integrated low-voltage, low-power DC-DC switching controller with an input voltage ranging from 4.5V to 16V. It is suitable for applications where high-speed switching needs to be achieved. The integrated high-speed power switch provides a maximum frequency of up to 1MHz, allowing the device to quickly respond to changes in input voltage.

The UCC38C45DGK features an integrated maximum-current protection circuit which helps to protect the device from possible overcurrent conditions. It also features a current-sense amplifier, integrated over-voltage protection and active-low enable functions. These features make it ideal for applications where high-speed switching is required, with minimal current draw and over-voltage protection.

The device integrates an internal oscillator circuit and a voltage conduction circuit for the output voltage control. This can be regulated by two external resistors, in order to adjust the comparator reference voltage and provide an adjustable feedback signal to the output voltage. The use of this adjustable voltage control, combined with the integrated MOSFET switch, enables the UCC38C45DGK to provide a range of output voltages and currents.

The device also features a number of additional features such as thermal shutdown, soft-start, and current-limit functions. These features allow the internal operation to be adjusted and optimized according to the user’s requirements. The soft-start function allows the output voltage to gradually increase until the set value is reached. This eliminates the risk of over-voltage spikes and allows the device to start up quickly and efficiently.

The UCC38C45DGK is an incredibly versatile and efficient DC-DC switching controller, offering a wide range of features that can be used in many types of applications. It is perfect for use in medical and industrial environment, where high-speed switching and over-voltage protection are required, and can be used in a multitude of other applications. where a reliable and high-speed switching is needed.
