The integrated programmable input voltage range and extended output voltage range of the device make it an ideal choice for applications that require wide input range and low noise operation.

The CS5124XDR8 DC/DC switching regulator controller works by controlling the switching of an external power transistor to regulate the output voltage of the regulator. The device is designed to accept an external signal that commands the switching transistor to either open or close depending on the current input voltage to the regulator. When the input voltage is above the desired output voltage, the switching transistor turns off and the inductor current falls until the switch turns on again and the cycle repeats. By precisely controlling the switching of the transistor, the output voltage can be kept at the desired level.

The CS5124XDR8 also features a wide range of programmable voltage ranges as well as programmable output power limit settings, enabling a wide range of output power requirements. The device also includes internal current limit and adjustable soft start settings and provides built-in integrators for slope compensation and frequency modulation to reduce EMI. Additionally, the CS5124XDR8 provides a variety of pin-selectable options that can be used to optimize efficiency, maximize power, reduce size and simplify design.

The CS5124XDR8 DC/DC switching regulator controller is a reliable, efficient and exceptionally flexible offering for higher power applications in a variety of market segments. Its features, integrated features, and flexibility offer significant advantages for design engineers that need to meet increasingly challenging power requirements in their applications.
