ISL8025AIRTAJZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8025AIRTAJZ-T7A is a synchronous buck regulator from the ISL8025A series, manufactured by Renesas Electronics. It delivers 5 A continuous output current with an input voltage range of 2.7 V to 5.5 V and adjustable output from 600 mV to 5.5 V. The device operates at a default switching frequency of 2 MHz, adjustable between 500 kHz and 4 MHz. It features low ON-resistance FETs (36 mΩ P-channel high-side, 13 mΩ N-channel low-side) for high efficiency. Packaged in a TQFN-EP-16, it supports external synchronization and includes hiccup mode current limiting.
