详解Cypress公司的 Cypress S6BP501A／S6BP502A集成电路
cypress公司的s6bp501a／s6bp502a是三路输出功率管理集成电路,包括一个高压降压dc／dc控制器(dd3v),一个内置了fet的降压dc／dc转换器(dd1v)和一个内置了fet的升压dc／dc转换器(dd5v);电流模式架构具有快速负载响应特性,无负载时输入电流降至15 μa,输入电压宽至2.5v-42v,和aec-q100 (grade-2)兼容.主要用在仪表盘,汽车电子和工业应用.本文介绍了s6bp501a／s6bp502a主要特性,框图和架构图,应用电路及其所用材料清单,以及评估板s6sbp501a00va1001和s6sbp502a00va1001主要指标,框图,电路图,材料清单和pcb设计图.
s6bp501a／s6bp502a is a three channel output power management ic. this ic includes one high voltage buck dc／dc controller(dd3v), one buck dc／dc converter with built-in fets (dd1v) and one boost dc／dc converter with built-in fets (dd5v). currentmode architecture is used for fast load transient response. at no load, the input supply current is reduced to 15 μa (typ). it is possibleto provide stable output voltage under an automotive cold cranking condition until the input voltage falls to 2.5v. this ic is suitable forpower supply solutions of automotive and industrial applications. each output voltage can be adjusted by external resistors. bothdd1v and dd5v support the switching frequencies up to 2.4 mhz to allow use of small size inductors, which can reduce a partmounting area. to decrease emi, this ic equips a sync function that synchronizes to an external clock signal and a spread spectrumclock generator (sscg). when not inputting an external clock, it operates by an internal clock. the sscg is valid both internal clockand external clock. moreover, this ic has power good (pg) monitors for each output and a thermal-warning indicator.
