Description: Bold large current wiring + vias + window opening + make the temperature rise of the line smaller, more stable and lasting. The combined method of large electrolysis + post-stage LC filter filtering effectively filters out high and low frequency and switching noise. The chip itself has automatic over-current, over-heat and over-temperature protection. The default output is 5V, and the output voltage can be customized for free. (The positive voltage must be less than 3V or more of the power supply), the negative voltage must be the same as the supply voltage and less than 36V, please . Use high-frequency shielding inductors to effectively reduce radiation interference Small Size:Approx.40x46x20mm/1.57x1.81x0.79in, Save Space. Specification: High current output: 3A (peak 4A); Wide voltage input range: 5.5~36V; High conversion efficiency: up to 95% in the best condition; 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; With overcurrent protection and thermal shutdown function; With switch enable pin, only 17uA quiescent current in off state; Compared with other DC switching power conversion chips of the same type, the high conversion efficiency of TPS5430 is particularly worthy of attention. Package Includes: 1 Piece Power Module
