ISL8002AFRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002AFRZ-T is a monolithic synchronous step-down DC/DC converter from Renesas Electronics. It delivers up to 2A of continuous output current with an input voltage range of 2.7V to 5.5V and an adjustable output voltage from 0.6V to VIN. The device operates at selectable switching frequencies of 1MHz or 2MHz, utilizing peak current mode control for low duty cycle operation. It features integrated PMOS high-side MOSFETs to eliminate boot capacitors, supports PFM or PWM modes, and includes comprehensive protection mechanisms such as overcurrent, thermal, UVLO, and OVP.
