Texas Instruments TPS7A78EVM-041 Evaluation Module is designed to evaluate the TPS7A78 AC/DC linear regulator easily. The TPS7A78 regulator provides up to 120mA to the load with a 90VAC to 264VAC input.
The TI TPS7A78EVM-041 Evaluation Module features a single low standby power, variable output voltage, and linear regulator for various applications. The TPS7A78EVM-041 design is an evaluation system that allows the user to evaluate a wide range of applications and should not be used as a reference design for optimized minimum-size solutions.
