DESCRIPTION
The OM957XSP Integrated Switching Regulators are designed for pin compatibility with standard 3-
Pin linear regulators. The parts are ideally suited for non- isolated, point of load power regulation
applications where small size and high efficiency are required. The package is designed using “Chip-
on board” technology to reduce cost and maintain power density. This part will typically not require
any additional components in your application due to internal bulk capacity already provided.
