The UES2604 is a high current single-phase synchronous rectifier module, which is mainly used in various applications. It is well known for its high power efficiency, low on-resistance, fast reverse recovery time and low forward voltage drop.

The UES2604 is a high-performance device suitable for a wide range of applications. It is primarily used for switching high-current, low voltage power sources such as power converters, solar inverters, and electric vehicle chargers. It is also suitable for application of various DC/DC converters, as well as AC-DC or DC-DC linear regulators.

The working principle of the UES2604 is based on a synchronous rectification technique. It consists of four cells, each of which contains two antiparallel diodes connected in series. By properly switching the gate signals to each cell, a low voltage drop can be achieved. When the gate voltage of a cell is HIGH, the two antiparallel diodes will both be forward biased, allowing current to flow from the drain to the source with very little voltage overshoot. When the gate voltage of a cell is LOW, both diodes will be reverse biased and no current can flow.

The UES2604 also incorporates a reverse blocking function, that is, regardless of the gate voltage, the reverse current is blocked. This provides safety and improved performance in high-voltage applications. The device also has an over-current protection capability and can withstand high-frequency operation up to 50kHz.

The UES2604 is a cost-effective, high-performance single-phase synchronous rectifier module. It offers high power efficiency, low on-resistance, fast reverse recovery time and low forward voltage drop, making it suitable for a variety of applications. The device’s reverse blocking function and over-current protection capability make it an ideal choice for high-voltage applications.
