Introduction:

ISL6410IUZ-T5K is a family of DC-to-DC switching regulators from Intersil Corporation. It is designed to provide an integrated power solution for systems requiring one or more DC-to-DC regulators. This device provides robust operation in an industry standard footprint, with a maximum power rating of 100 Watts, an efficiency of up to 94%, and features such as an adjustable switching frequency and pulse-by-pulse current limit. The ISL6410IUZ-T5K family is divided into two product lines, the ISL6410IUZ (single channel) and the ISL6410IUZ-T5K (dual channel), both of which offer customers a range of solutions to suit their application needs.

Application Field and Working Principle:

ISL6410IUZ-T5K DC-to-DC switching regulators are used in a variety of applications including portable devices, telecom/networking equipment, point-of-load converters, gaming machines, and test & measurement equipment. Its adjustable switching frequency (270KHz to 1.2MHz) and small footprint make it an ideal solution for highcurrent applications. The device can also be used in unison with other regulators such as linear regulators, to provide a complete power management solution.The working principle of the ISL6410IUZ-T5K switching regulators is based on the principle of inductor-capacitor conversion. The regulator utilizes an integrated high-frequency power stage, pulse-by-pulse current limit, and a dedicated feedback pin to provide tight regulation. During the inductor-capacitor conversion process, the inductor acts as a switch between the input and the output capacitors. As the regulator converts the input voltage to the output voltage, the inductor current builds up, then slowly decays as the filter capacitor starts to charge.In addition, the ISL6410IUZ-T5K switching regulators are designed with a synchronous rectification technique, which reduces overall power losses by eliminating the need for an externally controlled rectifier. This helps to improve power efficiency and reduce power dissipation, resulting in improved system efficiency. The device also features a low standby current of only 120μA, making it suitable for low power applications.The ISL6410IUZ-T5K DC-to-DC switching regulators are designed with advanced features to ensure robust operation and minimize component count. The integrated power stage features a switch node that maintains low EMI emissions and reduces the susceptibility of switching noise. The device also includes advanced protection features such as a micro-power shutdown (MSD) to prevent over-current and over-temperature faults.

Conclusion:

In conclusion, the ISL6410IUZ-T5K is a family of high-efficiency DC-to-DC switching regulators that offer system designers a range of flexible solutions for a wide range of applications. With its adjustable switching frequency, pulse-by-pulse current limit, and synchronous rectification, the device is able to provide improved performance and low total cost of ownership. Additionally, the device features built-in protection features to ensure robust operation and reduce component count. This makes the ISL6410IUZ-T5K ideal for a variety of applications, from portable devices to telecom/networking equipment.
