ISL8002BIRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002BIRZ-T is a monolithic synchronous step-down DC/DC converter manufactured by Renesas Electronics Corporation. It delivers up to 2A of continuous output current from an input supply ranging from 2.7V to 5.5V. The device utilizes peak current mode control architecture for low duty cycle operation and operates at a switching frequency of 2MHz. It features an adjustable output voltage range from 0.6V to 5.5V with a single positive output configuration. The component is housed in an 8-WFDFN package with an exposed pad, measuring 2mm x 2mm, suitable for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Supports selectable PFM or PWM operation modes to optimize light-load efficiency or reduce RF interference respectively.
• Includes comprehensive protection mechanisms such as overcurrent, short circuit, over-temperature, UVLO, and OVP.
• Capable of 100% duty cycle operation at 1MHz switching frequency with minimal dropout voltage.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring compact power solutions
• Industrial control systems with limited board space
• Battery-powered devices needing efficient step-down regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B' against the official datasheet to confirm the 2MHz switching frequency variant, as other suffixes may indicate different frequencies. Ensure the T tape-and-reel packaging matches your automated assembly requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2A output current capability and 2MHz switching frequency are required within a 2.7V to 5.5V input range. The 8-pin TDFN package is ideal for applications prioritizing small footprint and thermal performance. Consider the internal compensation option if external component count reduction is a priority, while noting that external compensation offers greater flexibility for stability optimization.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL8002BIRZ-T belongs to the ISL8002 family of compact synchronous buck regulators. This series is designed for high-efficiency power conversion in space-constrained environments. The family shares common architectural features like peak current mode control and integrated MOSFETs, with variations primarily defined by switching frequency and output current ratings across different suffix codes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL8002AIRZ-T: Offers identical functionality but operates at a 1MHz switching frequency instead of 2MHz. Verify if the lower frequency meets your inductor size and transient response requirements. Other ISL8002 variants may differ in current rating or package type; always cross-reference pinouts and electrical specifications.
