ISL68220IRAZ-T

DC DC Switching Controllers Overview

The ISL68220IRAZ-T is a digital dual output multiphase PWM controller from Renesas Electronics, featuring PMBus V1.3 compatibility. It supports flexible phase assignments up to two phases across two outputs (X and Y), including configurations such as 1+1, 1+0, or 2+0. The device utilizes a proprietary digital synthetic current modulation scheme for optimized transient response and efficiency. It operates with an input voltage range of 3.135 V to 3.465 V and provides a maximum output voltage of 3.05 V. Packaged in a 32-lead 4x4 mm QFN, it functions within a temperature range of -40°C to +125°C.
