The ISL6526CR-T is a dual-phase, high-performance synchronous buck Controller that is designed to provide up to 8A of output current per phase, with a 0.9V to 5.5V output voltage range. This particular 6-pin component is employed for applications like point-of-load regulation, power distribution, server and telecom, and as a general-purpose buck controller. It is capable of regulating high output currents with up to 90% efficiency and offers an adjustable switching frequency, allowing for tighter component selection and improved noise frequency coordination. The operating temperature range between -40°C to 125°C and the 6-pin package size offer multiple opportunities for use in lower profile applications.

The ISL6526CR-T supports two integrated high-side drivers and four integrated low-side drivers in its dual-phase operation. It also features internal soft-start and remote sensing, as well as features like programmable maximum duty-cycle, sleep, fast-power-up, output duty cycle, over-voltage protection, power good, and power warning. The remote sensing feature of this component allows for the output voltage to be automatically adjusted by sensing the output voltage through an external resistor. This ensures accuracy in the output voltage, even when line and load conditions may vary.

The working principle of the ISL6526CR-T is quite straightforward. It is capable of regulating up to 8A of output current per phase with a 0.9V to 5.5V output voltage range. It does this by utilizing two integrated high-side drivers and four integrated low-side drivers. The working principle behind each of these drivers involves a sense amplifier that detects the output voltage and acts as the reference for the driver. The driver then converts the voltage reference into the necessary voltage or current in the output.

Once the voltage is set, the ISL6526CR-T moves on to the next stage - controlling the output current. This is done by way of a voltage-mode control loop that senses the output current through a sense resistor and compares it to an internal reference. This comparison adjusts the duty cycle of the low-side and high-side drivers, allowing for precise control of the output current. The voltage-mode control loop is also capable of soft-starting the regulator, which allows for smooth operation at start-up.

The ISL6526CR-T is ideally suited for applications like point-of-load regulation, power distribution, server and telecom, and as a general-purpose buck controller. It offers wide operating temperature ranges and a 6-pin package size. It also features internal soft-start and remote sensing, as well as features like programmable maximum duty-cycle, sleep, fast-power-up, output duty cycle, over-voltage protection, power good, and power warning. As such, the ISL6526CR-T is a versatile and reliable component that can easily meet the needs of a range of applications.
