Wx-dc12003 Schematic Jun 2026

IC1 (LM2596) pins: 1 - VIN (12V) 2 - OUTPUT (SW) 3 - GND 4 - FB (Feedback) 5 - ON/OFF (tied to GND = always on)

The IC chops the smoothed 310V DC into a high-frequency square wave (often operating between 60 kHz and 100 kHz), driving the primary winding of a miniature high-isolation step-down transformer. 3. The Secondary Output Stage (Isolation & Filtering) wx-dc12003 schematic

is a highly reliable part for its price, keep two core design characteristics in mind during deployment: IC1 (LM2596) pins: 1 - VIN (12V) 2
