ISL8014IRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8014IRZ-T is a monolithic synchronous buck DC/DC converter manufactured by Renesas (formerly Intersil). It delivers up to 4A of continuous output current from an input voltage range of 2.7V to 5.5V, with adjustable output voltages between 800mV and 5.5V. Operating at a fixed switching frequency of 1MHz, the device utilizes a current control architecture for fast transient response and low duty cycle operation. It integrates low on-resistance P-channel and N-channel MOSFETs within a 16-lead QFN-EP package.
