MP5424 Power Management Integrated Circuit (PMIC)

Monolithic Power Systems (MPS) MP5424 Power Management Integrated Circuit (PMIC) is a complete power management solution in a single package. The MP5424 integrates four high-efficiency step-down DC-DC converters, three low-dropout (LDO) regulators, one load switch, and a flexible logic interface. Constant-on-time (COT) control in the DC-DC converter provides a fast transient response. The MP5424 features a 1.1MHz default switching frequency (f_SW) during continuous conduction mode (CCM). This feature greatly reduces the external inductance and capacitance. Full protection features include under-voltage lockout (UVLO) protection, over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.
