MPQ4436/4436A Switching Voltage Regulators Monolithic Power Systems (MPS) MPQ4436/4436A Switching Voltage Regulators are frequency programmable regulators with integrated internal high-side and low-side power MOSFETs. These voltage regulators feature an external soft-start, multi-phase capability, power good output, low dropout mode, and out-of-phase synchronized clock output. The MPQ4436/4436A regulators include symmetric VIN for low EMI, selectable Advanced Asynchronous Mode (AAM) or Forced Continuous Conduction Mode (FCCM), and hiccup overcurrent protection.
