mp3910峰值电流模式提高可编程频率PWM控制器
分享资料个
The MP3910 is a Peak Current Mode PWM controller that can drive an external MOSFET capable of handling more than 10A current. It has a typical operational current of 288µA and can accommodate flyback， boost for nonisolated and isolated applications. Current mode control provides inherently simple loop compensation and cycle-by-cycle current limit. Under-voltage lockout， soft-start， internal regulated supply and slope compensation are all provided to minimize the external component count. While designed for Flyback applications， the MP3910 can also be used for other topologies including Boost， Forward and Sepic. The 1A gate driver minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices. Additionally， MP3910 has pulse skipping mode function that improves the efficiency with light load or no load. It also provides hiccup protection for OLP， OVP and SCP condition. The MP3910 is available in MSOP10 package.
