Circuit Schematic Smart Power Supply for Microcontroller Projects using TPS63000 IC

Eltronicschool. - There are many electronic circuit schematic that design to produce best power supply for many electronic device. One of the best smart power supply is designed to supply microcontroller project like in Figure 1 below. The main component in this circuit schematic is TPS63000 IC.

Circuit schematic like in Figure 1 above is Circuit Schematic Smart Power Supply for Microcontroller Projects using TPS63000 IC. According Electroschematics site describe that the design is centered around TPS63000 (IC1), the high-efficient single inductor buck-boost converter from Texas Instruments. Here the power supply offers a regulated 3.3V/5.0V output, processed from an input voltage range of 1.8 V to 5.5 V, with up to 96% efficiency. We can use either a usb port power (through J1), a two-cell or three-cell alkaline, NiCd or NiMH battery, or a Li-ion/Li-polymer battery (through J2) as the input of this power supply. Note that the buck-boost conversion of TPS63000 is based on a fixed frequency, pulse width modulation controller using synchronous rectification to obtain maximum efficiency.

Within the TPS6300x family, there are fixed and adjustable output voltage versions available. Here we used its adjustable ouput version, and connected a resistor divider (R2-R4) between VOUT, FB and GND of TPS63000. If the jumper (JP1) is in open condition, the final output voltage (available at J3) is 5 V, and if the jumper is closed, the same output voltage is locked to 3.3 V.. Read more here.
