The MAX20733EVKIT is a complete evaluation board for the MAX20733 high-voltage integrated PWM controller and driver. The MAX20733 is ideal for low power off-line AC/DC and DC/DC power supplies, used in both consumer and industrial equipment. It integrates all active functions into a single chip, including a powerful MOSFET gate driver, full scale PWM control, easy to use startup and protection features, and a low noise oscillator.

The MAX20733EVKIT application field is primarily in low power off-line AC/DC and DC/DC power supplies. It is designed to operate with an input voltage range from 8V to 400V, allowing it to be used in a wide range of applications including lighting, medical products, consumer electronics, home appliances and other consumer products.

The MAX20733EVKIT also has the advantages of low power consumption, low EMI, and low cost. Its low power consumption is due to the small internal PCB area, which allows the PCB current to be minimized and efficiency maximized. The integrated PWM control circuitry eliminates the need for external components, resulting in a very cost effective solution. Also, the integrated PWM control circuitry reduces EMI by 30%.

The MAX20733EVKIT working principle is based on phase-shifted full bridge control. This method of control is designed to optimize light load efficiency. In this mode, the device sets the input voltage to the minimum required to meet the target output, and it does not switch off the power MOSFETs during light load conditions. This helps to keep the input current low, resulting in improved overall efficiency at light load.

The MAX20733EVKIT can be used to generate a regulated output voltage of 5V to 400V. It has a wide operating frequency range from 20kHz to 1MHz, and can be set via an external resistor. It also has a range of protection features, such as OVP (Over Voltage Protection), UVP (Under Voltage Protection), HVP (High Voltage Protection), and TSD (Thermal Shut Down).

The MAX20733EVKIT is an ideal solution for both AC/DC and DC/DC power supplies. It offers all the advantages of having a single chip solution for low power applications, at a very cost effective price. It is also designed to provide high efficiency and low EMI performance.
