MP3910GK

MP3910 The Future of Analog IC Technology Peak Current Mode Boost PWM Controller with Programmable Frequency, External Soft Start, and Light Load Operation DESCRIPTION FEATURES 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.      5V to 35V Supply Voltage Range(1) 1A 12V MOSFET Gate Driver External Soft-Start Pulse Skipping Operation with Light Load Programmable Switching Frequency (30kHz-to-400kHz) Frequency Synchronizable from 80kHz-to400kHz Cycle-by-Cycle Current Limit Over Voltage Protection Short Circuit Protection Over Temperature Protection Available in an MSOP10 Package APPLICATIONS     Telecom Isolated Power Supplies Brick Modules Off-line Controller General Step Up Applications All MPS parts are lead-free and adhere to the RoHS directive.
