ISL6549CRZ-TR5213

Overview

The ISL6549CRZ-TR5213 is a dual regulator power controller manufactured by Intersil, housed in a 14-SOIC package. It integrates a synchronous rectified buck PWM controller and a linear LDO regulator powered by a single 12V input supply. The switching frequency ranges from 150kHz to 1MHz, with an operating temperature range of 0°C to 70°C. The device requires a 4.75V to 5.25V supply voltage for internal logic operation.

Feature Summary

Integrates a synchronous buck PWM controller and a linear regulator in a single package
Operates from a single 12V input supply
Features adjustable switching frequency up to 1MHz

Applications

Single 12V input supply systems requiring dual regulation
Telecom infrastructure equipment
Industrial control systems

Procurement Notes

Verify the specific suffix TR5213 against official Intersil documentation to confirm tape and reel specifications. Ensure the component matches the 14-SOIC package dimensions and lead finish requirements specified in the datasheet. Cross-reference the manufacturer date code and lot number for authenticity.

Selection Notes

Select this component when a compact solution is needed for generating two distinct regulated voltages from a 12V source. The combination of synchronous buck efficiency and LDO noise filtering makes it suitable for mixed-signal applications. Verify that the thermal performance of the SOIC package meets the system's heat dissipation requirements.

Part Context

This part belongs to the ISL6549 family of dual regulator controllers. Similar variants include the ISL6549CA and ISL6549CB, which share the same core functionality but may differ in packaging or environmental ratings. The series is designed for applications requiring efficient power conversion from standard 12V rails.

Replacement Considerations

Direct replacements include the ISL6549CA and ISL6549CB. Verify pin compatibility and electrical parameters before substitution. Alternative manufacturers such as Richtek offer similar topologies like the RT9218B, but functional equivalence must be confirmed via detailed datasheet comparison.
