Working Principle

The CS5206-3GDPR3 is a linear voltage regulator with a 4-phase synchronous rectifying architecture. It consists of four switching leg circuits which are interconnected to form a closed loop. Each leg is independently regulated and can be configured for either buck or boost regulation.When in buck mode, the regulator switches the main power switch on when the voltage at its output falls below that of the feedback voltage. The regulator then turns off the switch when the output voltage reaches the set point. In boost mode, the regulator functions in reverse, switching the main power switch on when the voltage at its output is higher than that of the feedback voltage, and turning off when the output voltage reaches the set point.The synchronous rectifying architecture allows the power switch to be held in either on or off state for a given amount of time, thus improving efficiency. The regulated output voltage is determined by the average voltage drop across each power switch during the switching process. In order to maintain a constant output voltage, the CS5206-3GDPR3 incorporates feedback control and fault monitoring features.

Conclusion

The CS5206-3GDPR3 from California Simtek Corp is an integrated switching regulator controller and multi-phase voltage regulator designed to provide 5.0V output at a maximum output current of 3A with a typical efficiency of 96.5%. It has a wide range of features, including 4-phase synchronous rectifying architecture, low power loss, adjustable switching frequency, and adjustable output current limit, making it suitable for a variety of applications. The working principle of the CS5206-3GDPR3 is based on a 4-phase synchronous rectifying architecture, allowing for improved efficiency and consistent output voltage.
