ISL6388HRTZ-TR5714

Special Purpose Regulators Overview

The ISL6388HRTZ-TR5714 is a single-output PWM controller manufactured by Renesas Electronics Corporation, designed for Intel processor voltage regulation modules. It operates with a switching frequency of 1.5 MHz and supports an input voltage of 14 V. The device delivers up to 180 A output current at a regulated output voltage of 3.04 V. Housed in a 40-pin TQFN package measuring 5 mm by 5 mm with a height of 0.75 mm, it weighs 65 mg. The component exhibits moisture sensitivity classification and requires specific handling protocols during surface mount assembly.

Special Purpose Regulators Procurement Notes

Verify the exact suffix TR5714 against official Renesas documentation to confirm reel size and tape specifications. Ensure compatibility with standard SMD/SMT assembly processes given the 40-TQFN package dimensions. Confirm moisture sensitivity level requirements prior to storage and reflow soldering procedures to prevent package damage during manufacturing.

Special Purpose Regulators Selection Notes

Select this component for applications requiring precise single-phase control for Intel processors. Evaluate thermal performance due to the 180 A output rating within the small 5x5 mm package. Consider the 1.5 MHz frequency impact on inductor selection and PCB layout constraints compared to lower-frequency alternatives.
