Current Mode PWM Controller 2.5mA 8-Pin SOIC T/R

The MP3910A 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 400µA and can accommodate flyback, boost for non-isolated and isolated applications. Current mode control provides inherently simple loop compensation and cycle-by-cycle current limit. Under-voltage lockout, soft-start and slope compensation are all provided to minimize the external component count.While designed for Flyback applications, the MP3910A 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, MP3910A 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 MP3910A is available in SOIC8 package. 9V to 14V Supply Voltage Range 1A MOSFET Gate Driver External Soft-Start Pulse Skipping Operation with Light Load Programmable Switching Frequency (30kHz-to-400kHz) Cycle-by-Cycle Current Limit Over Voltage Protection Short Circuit Protection Over Temperature Protection Available in SOIC8 Package
