SN6507DGQEVM Low-Emissions 500 mA Push-Pull
Transformer Driver for Isolated Power Supplies
Evaluation Module
ABSTRACT
This user's guide describes the evaluation module (EVM) for TI’s SN6507 push-pull isolation transformer driver.
This EVM helps designers analyze and evaluate performance of the SN6507 device for quick development of
isolated power supplies.
In addition to the SN6507 device, this EVM contains a small form-factor transformer, simple rectifier circuit,
voltage regulator, and various adjustable options. These combinations simulate a complete isolated power
supply system suitable for many applications.
