جهت دانلود دیتاشیت چیپ به این لینک مراجعه نمایید.
TPS5430 Official Parameters:
High Current output : 3A ( peak 4A)
Wide voltage Range : 5.5V-36V
High Conversion efficiency : The best condition up to 95%
Wide output voltage Range :500KHz fixed conversion rate
Have overcurrent protectionand thermal shutdown function
having a switch enable pin , off states only 17uA quiescent current
internal soft-start compared to other similar types of DC switching power conversion chip
TPS5430 high conversion efficiency of particular concern
Actual Product parameters:
our product is the positive and negative voltage output , convenient buyer power project design, although the official PDF gives a wide voltage range of 36 V , he peak current of 4A, but we recommend using a vlotage not exceeding 30V , current control in less than 2.5A .
our product ripple out the actual test result :positive voltage is approximately 24mV around, a negative voltage is probably 40mV round .
I believe understand electronic friends all know, the switching power supply can have such parameters has been very good.Also,according to experience,TPS5430 measured out the conversion efficiency of about 88% , not the official 95% is so high .negative voltage conversion efficiency less than positiva voltage.
