MP3910A Peak Current Mode Boost PWM Controller with Programmable Frequency, External Soft Start Light Load Operation, and SOIC8 Package The Future of Analog IC Technology DESCRIPTION FEATURES 9V to 14V Supply Voltage Range The MP3910A is a Peak Current Mode PWM 1A MOSFET Gate Driver controller that can drive an external MOSFET External Soft-Start capable of handling more than 10A current. It has a typical operational current of 400A and Pulse Skipping Operation with Light Load can accommodate flyback, boost for non- Programmable Switching Frequency isolated and isolated applications. (30kHz-to-400kHz) Cycle-by-Cycle Current Limit Current mode control provides inherently simple Over Voltage Protection loop compensation and cycle-by-cycle current Short Circuit Protection limit. Under-voltage lockout, soft-start and slope Over Temperature Protection compensation are all provided to minimize the Available in SOIC8 Package external component count. While designed for Flyback applications, the APPLICATIONS MP3910A can also be used for other topologies Telecom Isolated Power Supplies including Boost, Forward and Sepic. The 1A Brick Modules gate driver minimizes the power loss of the Off-line Controller external MOSFET while allowing the use of a General Step Up Applications wide variety of standard threshold devices. PoE Powered Devices Additionally, MP3910A has pulse skipping All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
