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 .
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 CD4047 CMOS-based two-MOSFET inverter circuit board is a square wave inverter that oscillating the input DC voltage at 50-60Hz frequency using an external transformer to produce a 220V AC output. This mini inverter can be handy for camping and outdoor emergency work where electricity is unavailable to charge your device batteries with a charger or power AC light bulbs. Here, we will discuss and explain the workings of this simple DC-AC power converter along with its circuit diagram .
