ISF1212A Equivalent & Substitute Parts Reference

Part Overview

The ISF1212A, manufactured by XP Power, is an isolated module DC-DC converter designed for ITE (Commercial) applications. It provides a regulated 12V output at up to 84mA, with input voltages ranging from 10.8V to 13.2V. The converter delivers 1W of power with 1kV isolation and features a surface mount 8-SMD module packaging. The ISF1212A is classified as obsolete, making it necessary to identify direct substitute parts for design continuity and production support.
