Monolithic Power Systems (MPS) MPQ4214 40V Synchronous Buck-Boost Controllers

Monolithic Power Systems (MPS) MPQ4214 40V Synchronous Buck-Boost Controllers feature a wide input voltage range, high efficiency, and I2C interface. The MPS MPQ4214 controllers have programmable features like output voltage, slew rate, and constant output current limit. Ideal for USB Type-C™ power supplies, the devices utilize valley current control in buck mode and peak current control in boost mode, ensuring quick load responses and smooth transitions between modes. With forced continuous conduction mode (FCCM) and a programmable average current limit, the devices accommodate flexible designs for various applications.
