电源管理集成电路（PMIC）_S6BP401A主要特性

　　S6BP401A is a power management IC， consists of quad buck 2.1 MHz DC/DC converter with built-in switching FETs， dual LowDrop-out regulator （LDOs） and a digital windowed watchdog TImer. Having the switching FETs built-in， S6BP401A realizes highpower conversion efficiency and high switching frequency up to 2.4 MHz. The internal FETs are capable to handle up to 3A load. AsS6BP401A employs the current mode architecture， it has fast load transient response. Built-in output voltage setTIng resistors andcompensaTIon circuits reduce BOM cost and component area.
