[原创] Cypress S6BP203A汽车电源管理(PMIC)解决方案

Cypress公司的S6BP203A是42V 2.4A同步降压-升压DC/DC转换器,有四个内置的开关FET,输入电压2.5V-42V,输出电压3.3V,负载电流2.4A,开关频率200 kHz - 2.1 MHz,主要用在汽车驾驶辅助系统(ADAS),仪表盘和工业应用.本文介绍了S6BP203A主要特性,框图,应用案例电路图及其材料清单,以及汽车PMIC评估板S6SBP203A8FVA1001主要指标,框图,电路图,材料清单,PCB元件布局图和PCB设计图.

S6BP203A is a 1ch Buck-boost DC/DC converter IC with four built-in switching FETs. This IC is able tosupply up to 2.4A of load current within the very wide range from 2.5V to 42V in the input voltage. This IChas an operation mode that is automatically changed to PFM operation during low load, which can achievesuper-high efficiency with a very low quiescent current 50 μA. It is possible to provide stable output voltagefrom an automotive cold cranking and load dump, up to 42V, conditions within 1 ms transition time. As aresult, this IC is suitable for power supply solutions of automotive and Industrial applications.
