Maximum output current: 1A.According to the official data sheet, the theoretical maximum output current is 3A; however, at this level, the chip will generate heat and output voltage ripple will increase. Therefore, when the power consumption exceeds 6W, to ensure the module operates normally, please ensure you install a heat sink for the TPS5430 chip to dissipate heat, thereby avoiding unnecessary damage. The recommended maximum output current is 1A.2. Module efficiency: The higher the input voltage, the lower the power supply output efficiency; power supply efficiency also decreases as the load decreases; efficiency on the negative voltage side is lower than that on the positive voltage side.For example, with an input voltage of 12V and an output of ±5V, when the output is connected to a 10Ω load, the efficiency on the +5V output side is no less than 82%, whilst the efficiency on the -5V output side is no less than 75%.3. Module Output DC Voltage RippleWith a 12V input and a ±5V output, the ripple is less than 6mV under no-load conditions. When the output is connected to a 10Ω load, the ripple on the +5V output is approximately 10mV, whilst the ripple on the -5V output is approximately 40mV.The higher the input voltage, the greater the ripple; the heavier the load, the greater the output ripple.Package ContentsTPS5430 DC-DC step-down module × 1
