DC DC Switching Controllers datasheet and documents for ISL6420BIAZ-T7A

ISL6420BIAZ-T7A

DC DC Switching Controllers Overview

The ISL6420BIAZ-T7A is an advanced single synchronous buck pulse-width modulation (PWM) controller manufactured by Renesas Electronics Corporation. It operates from a 5.5V to 28V input voltage range and features a 0.6V internal reference voltage with ±2.0% accuracy. The switching frequency is resistor-selectable between 100kHz and 1.4MHz, with a maximum duty cycle of 96%. Designed for N-Channel MOSFETs in a synchronous rectified topology, it integrates control, output adjustment, monitoring, and protection functions into a single package.

DC DC Switching Controllers Feature Summary

Integrates complete control and protection schemes for high-performance DC/DC buck converters
Supports external reference voltage tracking mode for externally referenced applications
Features voltage margining mode for system testing in networking DC/DC converter applications
Provides simple, single feedback loop, voltage-mode control with fast transient response

DC DC Switching Controllers Applications

Externally referenced buck converter applications
DDR termination supplies
Networking DC/DC converter applications requiring voltage margining

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'IAZ' against official Renesas documentation, as standard listings often cite 'IRZ'. Confirm current component status, as the ISL6420B series has been subject to obsolescence notices. Ensure compatibility with required packaging formats such as tape and reel or cut tape when sourcing replacements.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring adjustable switching frequencies up to 1.4MHz and precise output regulation down to 0.6V. It is suitable for applications needing integrated lossless overcurrent protection and programmable soft-start. Consider the 20-QFN package for space-constrained PCB layouts requiring improved efficiency.

DC DC Switching Controllers Part Context

The ISL6420B belongs to the ISL6420 family of synchronous buck PWM controllers. It simplifies implementation by integrating error amplifiers, drivers, and protection circuits. The device supports both 4.5V-5.5V and 5.5V-28V input ranges depending on the specific variant configuration.
