ISL8117AFRZ-T Buck Regulator Positive Output Step-Down DC-DC Controller IC 16-QFN

Description

The ISL8117 is a 60V high voltage synchronous buck controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal. Programmable switching frequency ranging from 100kHz to 2MHz helps to optimize inductor size while the strong gate driver delivers up to 30A for the buck output.

Specifications

The ISL8117DEMO1Z demonstration board is designed for high current applications. The current rating of the ISL8117DEMO1Z is limited by the FETs and inductor selected. The electrical ratings of ISL8117DEMO1Z are shown in Table 1.
