ISL6535IRZ-T

DC DC Switching Controllers Overview

The ISL6535IRZ-T is a high-performance synchronous buck pulse-width modulator (PWM) controller manufactured by Renesas Electronics. Designed for demanding DC/DC converter applications, it features voltage-mode control and supports safe startup into prebiased output loads. The device provides precise output voltage regulation with a maximum tolerance of ±1% over the commercial temperature range and ±1.5% over the industrial temperature range. It operates within an input voltage range of 10.8 V to 13.2 V, with a nominal rating of 12 V. The component includes overcurrent fault protection and utilizes a 14-lead package.
