The SG3525 IC-based two-MOSFET inverter circuit board is a square wave inverter that oscillates the DC input voltage at an 18-24 kHz high frequency, using an onboard ATX transformer to generate a 220V AC output voltage. This compact inverter can be handy for camping and outdoor emergencies where electricity is unavailable to power AC light bulbs. Here, we will discuss and explain the workings of this Chinese DC-AC power converter along with its circuit diagram .
The SX1308 DC to DC step up converter module is a adjustable power boost converter circuit board, which can convert the input DC 2-24V to DC 2-28V output at a 95% efficiency rate, using 1.2 MHz switching frequency, and capable of delivering a maximum output current of 2 Amp. The internal soft-start of the IC SX1308 ensures smooth operation, while the automatic shifting to pulse frequency modulation mode at light loads further enhances the boost converter energy-saving capabilities and extends battery life. Here, we will discuss and explain the workings of this compact DC-DC step-up converter along with its circuit diagram .
The AMS1117-3.3V module is a voltage regulator circuit board with overheat protection functions. It can convert an input voltage range of 4.8V to 10.3V DC at 1A of current to a fixed +3.3V DC output. This can serve as an additional power supply for various electronic components, circuit boards, or power the LEDs (up to a maximum of 3 watts). Here, we will discuss and explain the workings of this compact DC-DC regulator power supply along with its circuit diagram .
