ISL6426CR

DC DC Switching Controllers Overview

The ISL6426CR is a synchronous buck switching regulator controller from Intersil, optimized for generating lower voltages. It integrates control, output adjustment, and protection functions into a single package. The device provides simple, single feedback loop, voltage-mode control with fast transient response. It features an error amplifier with a 15MHz gain-bandwidth product and 6V/µs slew rate, enabling high converter bandwidth. The unit operates within a frequency range of 100kHz to 700kHz and utilizes a 16-QFN (5x5) package.

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm the specific suffix 'CR' matches the required QFN package and temperature grade. Check current lifecycle status as older Intersil models may be obsolete or limited supply. Ensure ESD handling protocols are followed during storage and assembly due to moisture sensitivity classification.

DC DC Switching Controllers Selection Notes

Select this component when a fixed or adjustable synchronous buck solution is required for low-voltage applications. The integrated design reduces external component count compared to discrete solutions. Consider the 15MHz error amplifier bandwidth for designs demanding rapid load transient response. Verify that the input voltage range and switching frequency capabilities align with the target system power requirements.

DC DC Switching Controllers Part Context

This part belongs to the ISL64xx series of PWM controllers designed for notebook and portable electronics. It shares architectural similarities with the ISL6406 but offers specific integration levels for cost-sensitive applications. The series represents Intersil's approach to consolidating power management functions into compact packages for space-constrained mobile devices.
