ISL8104CRZ

DC DC Switching Controllers Overview

The ISL8104CRZ is a single-phase synchronous PWM controller designed for step-down DC/DC conversion. It operates with an input voltage range of 8V to 14V and features integrated MOSFET drivers. The device supports safe startup into prebiased outputs, making it suitable for DDR memory power applications. Packaged in a 16-lead QFN (4x4 mm) format, it provides a single non-isolated output.

DC DC Switching Controllers Feature Summary

• Integrated MOSFET drivers for synchronous buck topology
• Safe startup capability into prebiased output conditions
• Designed for high-performance DDR memory power regulation

DC DC Switching Controllers Applications

• DDR memory power supplies
• Single-phase synchronous step-down converters
• Systems requiring prebiased output startup

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (CRZ vs CRZ-T) against the required packaging type, as tape-and-reel options may exist. Confirm RoHS3 compliance status if environmental regulations are strict. Check current availability as this component may be subject to end-of-life notices or discontinuation by the manufacturer.

DC DC Switching Controllers Selection Notes

Select this controller when an 8V to 14V input range is required for DDR power rails. Ensure the application benefits from integrated drivers to reduce external component count. Verify that the 16-lead QFN package fits the PCB layout constraints and thermal requirements of the design.

DC DC Switching Controllers Part Context

The ISL8104 series includes variants like the ISL8101, which differs in input voltage range and pin count. The ISL8104 specifically targets the 8V-14V window, distinguishing it from lower-voltage inputs found in other family members. Evaluation boards such as the ISL8104EVAL2Z are available for testing.
