DESCRIPTION

The OM955X series of Switching Regulators are designed for pin compatibility with standard 3-

Pin linear regulators. They are well suited for on-board, non- isolated power applications where

efficient point- of- load regulation is needed. The package is designed using Chip- on – Board

technology to reduce cost and maintain power density. These units will typically not require any

additional components in your application due to capacitance provided internal to the package.
