ISL8560MREP

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8560MREP is a synchronous step-down DC/DC switching regulator manufactured by Renesas Electronics Corporation. It accepts an input voltage range of 9V to 60V and delivers up to 2A of output current. The output voltage is adjustable from 1.21V to 55V via an external resistor divider. Operating with a switchable frequency between 100kHz and 600kHz, the device integrates an internal power DMOS transistor with a typical on-resistance of 0.19Ω. It is housed in a 20-lead QFN package (6x6mm) with an exposed pad for thermal management.
