ISL85005FRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL85005FRZ-T7A is a synchronous buck regulator from the Renesas ISL85005 series. It integrates high-side and low-side FETs to deliver up to 5 A of output current. The device operates with an input voltage range of 4.5 V to 18 V and supports adjustable output voltages between 4.3 V and 5.5 V. It utilizes current-mode control with an internal oscillator operating at a switching frequency of 500 kHz. The component is housed in a 12-lead DFN (3x4 mm) package and functions within a temperature range of -40°C to +125°C.
