EVM3805-QB-33-01A

The EVM3805-QB-33-01A is a DC/DC & AC/DC (Off-Line) SMPS evaluation board. It is designed to evaluate the performance of the ICs in the EVM3805 family, which is created with the goal of developing a series of EMI-hardened, single-stage AC/DC switches using flyback topology.

The board is composed of an inductor, integrated power switch (IP-P3), an input bridge rectifier, and a few resistors and capacitors. It features a standard 480 W/24 V/ 5 Amp output. The regulated output voltage is adjustable, and can range from 1.5 to 33 V. A Flyback topology is used to provide the output voltage.

In terms of its application field, the EVM3805-QB-33-01A is an ideal solution for any application that requires constant, regulated output power. It is ideal for motor drives, switch mode power supplies, LED backlights, solar and fuel cell charging, and digital audio amplifiers.

The working principle of the EVM3805-QB-33-01A is based on a Flyback topology. This topology uses an inductor and transformer as its main components to store energy. When the switch is turned on, a current flows through the inductor and charges up the transformer. When the switch is turned off, the current is stopped, and the transformer releases the stored energy to power the load.

The board is equipped with a Buck-Boost controller, which is responsible for controlling the switching current and voltage levels. It is also capable of regulating the output current, even when there is a sudden change in the input voltage level. This capability makes the board ideal for controlling motors with varying load conditions.

In summary, the EVM3805-QB-33-01A is a DC/DC & AC/DC (Off-Line) SMPS evaluation board that is designed to evaluate the performance of the ICs in the EVM3805 family. It has a number of applications, including motor drives, switchmode power supplies, LED backlights, solar and fuel cell charging, and digital audio amplifiers. It is based on a Flyback topology and is equipped with a Buck-Boost controller for controlling the switching current and voltage levels.
