The LM8801TME-1.2EV/NOPB is an evaluation board designed specifically for offline SMPS (switched-mode power supply) applications, ranging from DC/DC to AC/DC (off-line) converters. It contains all the components needed to construct a basic SMPS, including an AC/DC converter, a DC/DC converter, a rectifier bridge, and an output filter. It is also suitable for other applications such as LED drivers, battery chargers, motor drives, and other high voltage power supplies.

The board has two main components: the control chip and the output stage. The control chip is a proprietary LM8801TME-1.2EV/NOPB chip, which is a high-performance integrated voltage regulator. It includes a voltage reference, analog-to-digital converter (ADC), Pulse Width Modulator (PWM), and linear voltage regulator. The chip provides a wide operating voltage range, making it suitable for both AC and DC applications. The output stage contains an EMI filter, a boost converter, an MOSFET, and an LC filter.

The LM8801TME-1.2EV/NOPB uses a four-step feedback circuit for voltage regulation. The chip captures an analog signal from the power supply and converts it into a digital form. The data is then processed by the PWM and the linear voltage regulator for precise voltage regulation. The output stage is then driven to the desired regulated voltage.

The LM8801TME-1.2EV/NOPB is suitable for a variety of SMPS applications. The chip has a wide input voltage range and can be used in both AC and DC systems. The board features a high power efficiency of 98%, allowing for higher power outputs and lower power dissipation. The output stage can support high switching frequencies and can be used for efficient control of motor loads. The board also includes an onboard EMI filter for improved flexibility and safety.

The LM8801TME-1.2EV/NOPB is a versatile, easy-to-use evaluation board for offline SMPS applications. It contains all the components needed to construct a basic SMPS, along with the necessary support circuitry. With its wide operating voltage range and efficient design, it is suitable for a variety of SMPS applications and motor loads.
