About This Product

■Summary

The MP3910A is a peak current mode PWM controller that drives external MOSFETs with currents greater than 10A. With a typical operating current of 400µA, it can support flyback, boost, and non-isolated and isolated applications. Current mode control inherently provides simple loop compensation and cycle-by-cycle current limiting. Undervoltage lockout, soft-start, and slope compensation are all provided to minimize external component count. The MP3910A is designed for flyback applications, but can also be used in other topologies such as boost, forward, and SEPIC. The 1A gate driver allows the use of various standard threshold ICs while minimizing external MOSFET power dissipation. Additionally, the MP3910A has a pulse-skipping mode feature that improves efficiency at light or no-load conditions. It also provides hiccup protection against OLP, OVP, and SCP conditions. MP3910A is offered in SOIC8 package.

■Features and benefits

・Supply voltage range from 9V to 14V ・1A MOSFET gate driver ・External soft start ・Pulse skipping operation under light load ・Programmable switching frequency (30kHz to 400kHz) ・Current limit per cycle ・Overvoltage protection ・Short circuit protection ・Overheat protection ・Provided in SOIC8 package

■Available product numbers

・MP3910AGS-P MP3910AGS-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
