The CS5301GDW32G DC DC switching regulator controller is a high performance, monolithic, low voltage regulator controller designed for off-line, DC-DC converter applications up to 350V. This open-loop, synchronous switching controller provides very low temperature coefficient and tight output voltage regulation over a wide operating temperature range.

The chip operates from an input voltage range of 5V to 32V and provides an output voltage range of 0.6V to 24V. This makes it suitable for a wide variety of applications, such as power-supplies for mobile devices, computer peripherals, servers, and point-of-load power supplies.

The CS5301GDW32G has several features that make it a great choice for DC-DC power converter applications. It includes a variable deadtime, programmable soft-start, programmable switching frequency, over-voltage protection, short-circuit protection, and inrush current protection. These features make it an ideal choice for multiple output and high-performance power supplies.

The CS5301GDW32G is based on a “fixed frequency and variable gap” control algorithm that reduces the instability associated with other control methods. This algorithm is a type of hysteretic control in which the switching frequency is fixed and the on- and off-times are adjusted in response to the load current, using a gap sensing technique. The chip also features adaptive auto-skip mode with small-ripple operation and dynamic regulation loop, which provide tight regulation with low output voltage ripple over a wide range of input and output voltages.

The CS5301GDW32G is a highly integrated and versatile device that provides the features and flexibility needed to deliver the most cost-effective high performance DC-DC converter solutions. Its features make it ideal for use in applications such as computer adapters, battery charger, and other portable and consumer applications.

In conclusion, the CS5301GDW32G is a high-performance, monolithic, and low-voltage synchronous switching DC-DC converter controller for power supply designs for up to 350V. It has several features that make it ideal for multiple output, high-performance power supplies, such as a variable dead-time, programmable switching frequency, over-current protection, and inrush current protection. It is highly integrated and features a “fixed frequency and variable gap” control algorithm to reduce instability, adaptive auto-skip mode, and a dynamic regulation loop to provide tight regulation with low output voltage ripple. The CS5301GDW32G is a great choice for DC-DC power converter applications.
