!free! - Wx-dc12003 Schematic
: The heart of the circuit is a single-chip offline switcher (such as a TOP series or similar integrated PWM/MOSFET IC). This IC handles the high-frequency switching into the primary side of the isolation transformer.
Because of its tiny footprint (approximately 23.5 x 18.1 mm), the WX-DC12003 is a favorite for: wx-dc12003 schematic
: Built-in overvoltage, overcurrent, overheating, and short-circuit protection. Schematic and Circuit Architecture : The heart of the circuit is a
: Powering sensors and wireless modules directly from wall power. Schematic and Circuit Architecture : Powering sensors and
: The AC input typically passes through a small EMI filter and a bridge rectifier. A high-voltage electrolytic capacitor (often 4.7µF, 400V) smooths the rectified DC.
The module's performance is defined by its ability to handle wide input ranges while maintaining a stable output. : AC 50V–277V or DC 70V–390V. Output Voltage : 5V ±0.15V. Maximum Output Current : 700mA (roughly 3.5W total power).
