描述

  Cypress公司的S6BP401A是电源管理集成电路(PMIC),包含有四个内置了开关FET的降压2.1MHz DC/DC转换器,两个低压降(LDO)的稳压器和数字窗口看门狗计时器.VIN输入电压4.5V-5.5V,内置开关FET的电流高达3A,主要用在汽车应用,先进驾驶辅助系统(ADAS),照相机系统如安全照相机和工业应用。本文介绍了S6BP401A主要特性,框图和架构框图,典型应用电路,以及评估板S6SBP401AJ0SA1001主要指标,电路图,材料清单和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.
