MPQ3910A-AEC1

The MPQ3910A is a peak-current mode, PWM, boost controller that can drive an external MOSFET capable of handling more than 10A of current. The MPQ3910A has a typical operational current of 288µA and can accommodate flyback, boost and sepic application.

Current-mode control provides an inherently simple loop compensation and cycle-by-cycle current limit. Under-voltage 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-skipping mode to improve the efficiency at light load or no load. Protection features include hiccup protection for overload protection (OLP), over-voltage protection (OVP), and short-circuit protection (SCP).

The MPQ3910A is available in an MSOP-10 package.
