Cypress公司的S6BP401A是用于汽车ADAS平台的电源管理集成电路(IC),包括内置了开关FET的四个降压2.1MHz DC/DC转换器,两个低压降(LDO)稳压器和数字视窗看门狗计时器.DC/DC转换器的VIN输入电压4.5V-5.5V,开关FET输出电流达3A,LDO的输入电压2.97V - 5.5V,主要用在汽车应用,先进驾驶辅助系统(ADAS),照相机系统和工业应用.本文介绍了S6BP401A主要特性,框图和架构框图,应用案例电路及其电路元件列表,以及评估板S6SBP401AJ0SA1001和S6SBP401AM2SA1001特性,主要指标,连接图,电路图和材料清单与PCB设计图.
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.
