AMS1117 3.3V 1A Regulator Power Supply Circuit

Image
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 .

SX1308 DC To DC Step Up Converter Circuit

Image
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 .

Universal Single 3.7V Battery Charger Circuit

Image
The Chinese universal single 3.7V battery charger is designed to safely and efficiently charge rechargeable Li-Ion (18650, 16340, 14500), AA, and AAA batteries with a voltage rating of 3.7V. It charges them to their nominal voltage of 4.2V while providing a steady current of 400mA. The charger incorporates a Bi-color LED that indicates the charging status, with the LED emitting a red light during the charging process and automatically switching to green when the battery is fully charged. Here, we will discuss and explain the workings of this 3V3 battery charger along with its circuit diagram .
