ISL8002BFRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002BFRZ-T is a monolithic, synchronous step-down DC/DC converter from the Renesas ISL8002 family. 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 supports switching frequencies of 1MHz or 2MHz. It integrates low rDS(ON) PMOS high-side and NMOS low-side MOSFETs, eliminating the need for a bootstrap capacitor. The converter offers selectable PFM or PWM light-load modes and operates at 100% duty cycle with a dropout voltage of 200mV at 2A output.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Embedded systems utilizing 3.3V or 5V input rails
• Space-constrained PCB designs prioritizing small footprint

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation to confirm exact electrical characteristics, as suffixes often denote temperature grades or package variations. Ensure compatibility with your board's thermal design due to the exposed pad requirement in the TDFN-EP-8 package. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during manufacturing.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, high-efficiency buck regulator is needed for inputs between 2.7V and 5.5V. The integrated PMOS driver simplifies the bill of materials by removing the bootstrap diode and capacitor. Consider the 1MHz or 2MHz frequency options based on available inductor size constraints and transient response requirements. Verify that the 2A output current meets the maximum load demands of the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL8002BFRZ-T belongs to the ISL8002 series of synchronous buck converters manufactured by Renesas Electronics (formerly Intersil). This series is designed for applications requiring high efficiency and small solution size. The part is housed in an 8-pin, 2mm x 2mm TDFN package with an exposed pad, occupying less than 0.10 square inches of board area for the complete converter solution.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical parameters carefully when considering alternative manufacturers.
