TPS5430 has good features, its performance and the main parameters are as follows: High current output: 3A (peak 4A); Wide voltage input range: 5.5 ~ 36V; High conversion efficiency: the best conditions up to 95%; Wide voltage output range: the minimum can be adjusted down to 1.221V; Internal compensation minimizes the number of external components; Fixed 500kHz conversion rate; Over current protection and thermal shutdown function; With switch enable pin, off state only 17uA quiescent current; Internal Soft-Start Compared with other DC switching power supply chips of the same type, the high conversion efficiency of the TPS5430 is of particular concern.
1. bold high-current alignment + vias + window + make the line temperature rise smaller, more stable and lasting 2. large electrolytic + after LC filter combination filter effectively filter high and low frequency ripple and switching noise 3. the chip itself has over-temperature overheating automatic protection 4. Positive voltage must be less than the supply of 3V or more, the negative pressure must be with the supply voltage and less than 36V. 5. the use of high-frequency shielded inductors effectively reduce radiation interference 6. the module size is 40mm * 46m.
