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.S6BP401A主要特性:Quad Buck DC/DC Converter (DD1 to DD4)VIN Input Range: 4.5V to 5.5VSwitching FrequencyExternal clock mode: 1.8 MHz to 2.4 MHzInternal clock mode: 2.0 MHz to 2.2 MHzBuilt-in Switching FETs up to 3ABuilt-in Output Voltage Setting ResistorsBuilt-in Compensation CircuitsDual LDO (LD1, LD2)VIN Input Voltage Range: 2.97V to 5.5VBuilt-in Output Voltage Setting resistorsPower Good Monitor Output for each DC/DC Converters,LDOsBuilt-in Windowed Watchdog Timer (WDT)Under Voltage Lockout (UVLO)Thermal Shutdown (TSD)Over Current Protection (OCP)Over Voltage Protection (OVP)Independent Enabling for each DC/DC Converters and LDOsLoad-independent Soft-StartBuilt-in Discharge ResistorsSmall 6 mm 6 mm QFN-40 PackageAEC-Q100 compliant (Grade-1)AO-Electronics 傲壹电子 官网： 中文网：ALPS ADI IR JRC/NJR KEC OTAX Seoul Semiconductor TI Walsin TechnologyS6BP401A应用:Automotive ApplicationsAdvanced Driver Assistance Systems (ADAS)Camera Systems such as Security CameraIndustrial Applications图1.S6BP401A框图图2.S6BP401A架构框图图3.S6BP401A典型应用电路评估板S6SBP401AJ0SA1001S6SBP401AJ0SA1001 and S6SBP401AM2SA1001 are the evaluation kit for power block of automotive ADAS platform.The board implements power management IC S6BP401A.图4.评估板S6SBP401AJ0SA1001外形图图5.评估板S6SBP401AJ0SA1001略图评估板S6SBP401AJ0SA1001主要指标:图6
