MPQ3910A is a peak current mode, PWM boost controller that can drive an external MOSFET capable of handling more than 10A of current. The device has a typical operational current of 288µA, and can accommodate flyback, boost and single-ended primary inductor converter (SEPIC) applications. Current-mode control provides simple loop compensation and cycle-by-cycle current limiting. Undervoltage lockout (UVLO), soft start (SS), an internal regulated supply and slope compensation are all provided to minimize the external component count. 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, the MPQ3910A uses pulse-skip mode to improve the efficiency under light loads or no load. The MPQ3910A is available in an MSOP-10 package. Applications include telecom isolated power supplies, back-up boosts and start-stop boosts.
