降压型DC/DC调压器,非同步降压型DC/DC调压器,SGM6232,SGMICRO

SGMICRO SGM6232是一种采用电流模式非同步降压型拓步结构和片内集成功率型MOSFET的DC/DC调压器。耐压高达38V、输出电流高达2A。 SGM6232工作电压范围为4.5V ~ 38V，输入电压在28V以内时输出电流能力高达2A。SGM6232降压型DC/DC调压器输出电压范围为0.8V ~ 28V，典型工作效率高达91%以上，开关频率为1.4MHz，关断时静态电流最大值低于18μA。SGM6232具有周期轮询限流检测功能、过热保护功能和软启动功能，以及可以规避由于输入电压不稳带来的系统误操作的欠压锁定功能。用于实现限制浪涌电流或输出电压的过冲。带散热焊盘的SOIC-8封装，可以极大改善整个芯片的散热能力。SGM6232降压型DC/DC调压器可广泛应用在需要应对高尖峰输入电压风险的降压电路应用，例如汽车电子，工业设备，DVD/PVR，医疗器械等领域。

下面的电路是SGM6232降压型DC/DC调压器的电源设计方案图：

SGM6232降压型DC/DC调压器的电源设计方案图

图1

图2这个表格是针对是图1，输出5V电压元件对应值，

图2

如果我们要输出3.3V时，所有器件是不用改动只需要调整R1，R2电阻值就可以，电压输出值得计算请参考如下公式：

Vout=(1+R1/R2)*VFB, VFB=0.8V 修改下 R1和R2阻值即可得 3.3 V= (1+R1/R2)*0.8。

SGMICRO SGM6232降压型DC/DC调压器工作温度范围达到扩展的工业标准-40℃到+85℃，注意：在设计PCB时，在裸焊盘（Exposed Pad）上放置多个过孔，一方面可以提高该调压器的散热效率，另一方面，可以通过顶层和底层及内电层接地，保证地平面的稳定性。在设计原理图和PCB时，该元件的裸焊盘必须接地。

D1是肖特基整流型续流二极管，选择任一型号的肖特基二极管即可。

电容采用贴片陶瓷电容，其材质最好选择X5R或X7R，确保外围电容在-40℃～85℃保持较小的误差，使DC/DC转换器工作稳定可靠。其额定电压不小于Vin或Vout的1.5倍以上。根据Vin和Vout的不同，选择不同额定电压，且封装尺寸尽可能最小的贴片封装陶瓷电容。
