MPQ3910A PWM Boost Controllers

Monolithic Power Systems (MPS) MPQ3910A PWM Boost Controllers are designed to drive an external MOSFET capable of handling more than 10A of current. These devices feature a typical operational current of 288µA and can accommodate flyback, boost, and Single-Ended Primary Inductor Converter (SEPIC) applications. The MPQ3910A controllers offer a configurable switching frequency ranging from 30kHz to 400kHz, an external Soft Start (SS), and a pulse-skip mode under light load operation. 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 controllers use pulse-skip mode to improve the efficiency under light loads or no load. Some of the protection features include hiccup mode for Over-Load Protection (OLP), Over-Voltage Protection (OVP), and Short-Circuit Protection (SCP). The MPQ3910A PWM boost controllers are ideally used in telecom isolated power supplies, backup boosts, and start-up boosts applications.
