ISL99227IRZ-T

Overview

The ISL99227IRZ-T is a Smart Power Stage (SPS) module from the Renesas ISL99227 series, designed for high-efficiency power conversion. It integrates high-accuracy control with a PQFN-32 package for surface mount installation. The device operates within an input voltage range of 4.5 V to 18 V and supports a maximum output current of 60 A. It delivers a fixed maximum output voltage of 3.3 V with a quiescent supply current of 15 mA. The component functions reliably across a temperature range of -40°C to +85°C, dissipating up to 12.5 W of power.
