Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MPQ4436AGRE-33-AEC1-Z

The MPQ4436AGRE-33-AEC1-Z is a synchronous step-down switching regulator designed for a wide input voltage range of 3.3V to 45V, making it suitable for various automotive and industrial applications. It can deliver a continuous output current of up to 6A while maintaining low quiescent currents of 1.7OºA in shutdown mode and 18OºA in sleep mode. The device features integrated high-side and low-side MOSFETs with on-resistances of 48m,Ѷ and 20m,Ѷ, respectively, which contribute to its efficiency. This regulator supports configurable switching frequencies from 350kHz to 1000kHz, allowing it to be optimized for different load conditions. It includes features such as an open-drain power good output, external soft start, and selectable advanced asynchronous modulation or forced continuous conduction modes. The MPQ4436AGRE-33-AEC1-Z is AEC-Q100 qualified, ensuring reliability in automotive environments, and is available in a compact QFN-20 package. Its design also incorporates protections against over-current and thermal shutdown, enhancing its robustness for demanding applications.
