A6985F5V

A6985F5V is a DC DC switching regulator for advanced point-of-load (POL) voltage regulation in computer and peripheral products where space is at a premium. It provides a high efficiency, galvanically isolated DC-DC step-down converter with two outputs, designed to take input voltages up to 12V or 24V. The A6985F5V enables designers to build highly reliable, ultra-high efficiency, point-of-load power supplies without the need for expensive inductors.

The A6985F5V DC-DC switching regulator features high efficiency and low ripple operation, providing an efficient and reliable power solution for modern computer and peripheral products. Its low-voltage design allows it to be powered by a single supply such as a laptop or desktop computer battery, eliminating the need for an external power source. The A6985F5V is also capable of supporting a wide range of output voltage levels, which can be easily adjusted for any application, providing designers with maximum flexibility with respect to available power levels.

The A6985F5V operates in a fixed-frequency, constant-on-time (CTO) mode, offering excellent line and load regulation capabilities. It has a wide range of current output capability, up to 25A, enabling it to power multiple loads simultaneously. Additionally, its active-clamp reset circuitry and programmable output voltage range make it suitable for a wide range of point-of-load applications.

The A6985F5V has a wide frequency range, with a maximum frequency of 250KHz, allowing it to deliver the highest possible switching frequency with a single clock to save cost and space. Its wide input voltage range allows it to be used with a variety of input power supplies. It also features an external forced PWM feature, allowing the switching frequency to be manually set. Additionally, the A6985F5V has an internal synchronous rectification, enabling it to operate at very low RDS(ON) for improved efficiency.

The A6985F5V also has multiple protection features to ensure reliability in a wide range of operating conditions. This includes over-voltage, current limiting, and thermal shutdown, providing designers with added assurance that the device will operate reliably in their intended application. It also features an external enable and sleep mode, allowing the device to be turned off when it is not in use, further prolonging its life.

In summary, the A6985F5V DC-DC switching regulator is a highly efficient and reliable solution for point-of-load voltage regulation applications, featuring high efficiency, a wide operating frequency range, and multiple protection features. It is a cost-effective solution that provides high performance and superior reliability for modern computer and peripheral products.
