【应用】隔离型DCDC SGM46000应用于工业等需要隔离的电源驱动,具有小体积、低成本优势
在工业、充电桩,逆变等大功率电气设备中,通常要求控制信号的Vcc都会要求与母线电压隔离,信号通常只要用数字隔离器或光耦就能实现隔离,而Vcc的隔离则必须使用带变压器的模块电源,目前在隔离式电源模块供应商,用的最多的就是金升阳的电源模块。
这里介绍一款圣邦微的隔离型DCDC SGM46000,其通过外挂一款变压器,就能实现小功率的隔离电压变换,从而实现为小功率IC提供隔离电源的目标。其应用原理图如下:
图1
整个电路只需一个电源IC SGM46000,再加一颗隔离式变压器组成,体积非常紧凑,最大输出功率可达3W,为Can通讯,数字隔离器等小功率IC供电绰绰有余,而相比金升阳的电源模块,不仅体积,成本都会更有优势。
另外其最大的一个特点就是,不仅能完成降压,而且还能支持升压转换,相比其他电源模块要么只能固定降压,要么固定升压式不同,SGM46000可支持多种不同拓扑的设计,达到更广泛的电路使用要求。
SGM46000降压式转换设计原理图如下:
图2
在后级配合一颗3.3V LDO即可完成5V转3.3V的隔离式电源转换。
SGM46000升压式转换设计原理图如下:
图3
仅仅只需更改后级滤波的电路拓扑,就可完成从降压到升压的电源转换,可实现5V转12V的升压隔离式电源转换。
另外,还支持同时输出正负压,设计如下:
图4
大功率的电气设备都会用到运放来做电流采样,而运放又需要正负电压同时供电,因此SGM46000的双电压输出电路还可以解决电路中需要正负压的场景,其拓展性远远高于普通的电源模块。

【应用】国产隔离DCDC电源芯片SGM46000用于储能变流器,最大输出功率可达3W,可为运放解决正负压供电的需求
基于该应用场景,圣邦微的SGM46000隔离DCDC电源芯片,搭配上外部的变压器可以实现隔离电源模块的功能,从而为小功率芯片供电。更重要的是这种方案可以为有特殊需求的客户提供负压电源。
【应用】可满足不同供电需求的电源芯片,低成本RS-485通信隔离方案
在输出电压30V以内、输出电流50mA以内均可利用圣邦微的SGM46000设计出一系列的工业电源,满足不同的485通信隔离芯片的供电需求。可以改善以往隔离型工业电源的设计复杂度较大、设计成本比较贵、体积比较大等缺点。
【应用】运行电压最大为600V的栅极驱动器SLM2110CG用于UPS,延迟匹配仅仅为10ns
在小功率的在线式UPS中,给电池充电的DCDC拓扑大多数用的都是BUCK-BOOST的电路。由于充电功率较低,负责控制BUCK-BOOST电路开关管的驱动器可以用非隔离型。数明的栅极驱动器SLM2110CG适用于此应用。
