Diodes are a type of semiconductor, usually in the form of a single PN junction, widely used as an electronic switch. Diodes can be found in a variety of applications, ranging from basic rectifiers for power supply circuits to complex logic circuits. The DSEC29-02AS is a rectifier array from Diodes Incorporated. It is designed specifically for high frequency, high efficiency power supply applications. This article will discuss the applications and working principles of the DSEC29-02AS.ApplicationsThe DSEC29-02AS is a fully integrated diode rectifying array optimized for high efficiency power supplies such as switch mode power supplies (SMPS). The device covers a wide range of frequencies due to its integrated snubber-free rectifying topology. It has an active voltage clamp protection feature and low forward voltage drop to optimize power supply efficiency.The DSEC29-02AS has an ultra-low RDS(ON) of 50 mΩ at 4.5 V, enabling higher efficiency and improved system dynamics. It has an integrated current sensing diode for monitoring, detecting and controlling output power. The device also offers under voltage lockout (UVLO) for improved latch-up safety. It has an operating temperature range of -55 to 150 degrees C and is available in SSOP packages.Working PrincipleThe DSEC29-02AS consists of four independent rectifiers coupled together. Each rectifier consists of an integrated trench-type MOSFET and an active clamping circuit. For high frequency applications, the active clamping is used to reduce the voltage drop and improve efficiency. The MOSFET does not require external gate drive or snubber to function and can be connected directly between the input and output terminals.When the diode rectifying array is used in a buck converter, for example, the input voltage is higher than the output voltage. Under this condition, the integrated trench-type MOSFET is turned on and the current flows from the input to the output. When the voltage across the MOSFET exceeds a certain threshold, typically 200 mV, the integrated active clamp circuit is activated and the current flow is limited effectively. This prevents damage to the MOSFET. Utilizing the DSEC29-02AS in a buck converter provides enhanced transient response, lower page time and improved power efficiency.ConclusionThe DSEC29-02AS rectifier array is a powerful and highly efficient device for power supply applications. Its integrated snubber-free rectifying topology makes it suitable for a wide range of frequencies and its active voltage clamp protection feature ensures improved safety. In addition, its low forward voltage drop makes it ideal for increasing power efficiency. The DSEC29-02AS is a reliable and cost-effective solution for a variety of power supply designs.The specific data is subject to PDF, and the above content is for reference
