ISL8002FRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002FRZ-T is a highly efficient, monolithic synchronous step-down DC/DC converter from 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 very low duty cycle operation and operates at switching frequencies of either 1MHz or 2MHz. This flexibility provides superior transient response and allows for the use of small inductors. The converter integrates very low rDS(ON) MOSFETs to maximize efficiency and eliminates the need for a boot capacitor due to its PMOS high-side switch. It supports both internal and external compensation options and can operate at 100% duty cycle with a dropout of 200mV at 2A output current.
