ISL8002FRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002FRZ-T7A 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, enabling very low duty cycle operation and superior transient response. It operates at a switching frequency of 2MHz, which allows for the use of small inductors. The output voltage is adjustable from 600mV to 5.5V. The component is housed in an 8-WFDFN exposed pad package with dimensions of 2mm x 2mm, designed for improved thermal performance.
