The TPS650001EVM-585 is an evaluation module from Texas Instruments which is specifically designed for off-line SMPS (switch mode power supply) applications such as DC/DC converters and AC/DC power supplies. The board contains two power stages: a 500mW isolated gate driver with MOSFET output stage and a non-isolated Fly-Back controller with an adjustable current limit.

The TPS650001EVM-585 can be used for a wide range of applications, such as automotive and industrial systems, home appliance, consumer electronics, lighting and audio systems. It is suitable for low to medium power applications with single and dual output configurations, and it can operate at up to 85 watts of output power. It also has several protection features such as short circuit protection, over voltage / over current protection, thermal shutdown protection, and a wide input voltage range.

The TPS650001EVM-585 works by converting an intermittent or step-up DC input voltage to a steady state, regulated output voltage. The system is designed to operate with either an AC or DC input voltage. The input is first rectified and then passed through an energy storage capacitor. This stores energy to be used for the operation of the load and also for producing the output voltage.

The circuit then uses a switching controller stage, which is typically a buck-boost or a fly-back converter, to convert the input energy into a required output voltage. The switching controller is responsible for controlling the gates of the MOSFETs in the power stage, which switches on and off with a carefully controlled frequency and pulse width modulation. The switching controller can be adjusted to meet a variety of different output voltage requirements.

The TPS650001EVM-585 has several features that make it very versatile and suitable for a wide range of applications. For example, it has a very high efficiency, high power density, low EMI levels, wide input voltage range, and a very low external component count. It also has over-temperature protection, over-voltage protection, and over-current protection.

Overall, the TPS650001EVM-585 is an excellent evaluation module for anyone looking to develop a reliable and efficient off-line power supply application that requires an isolated output stage. With its wide range of features, low external component count, and high efficiency, it is an ideal solution for a variety of applications.
