ISL78214ARZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78214ARZ-T is a high-efficiency, monolithic synchronous step-down DC/DC converter manufactured by Renesas Electronics Corporation. It delivers up to 4A of continuous output current from an input voltage range of 2.8V to 5.5V. The device features a positive adjustable output starting at 0.8V, with a maximum output voltage of 5.5V. Operating with a fixed switching frequency of 1MHz, it utilizes a 16-VQFN package with an exposed pad for thermal management. The regulator supports surface mount installation and functions within a temperature range of -40°C to +85°C.
