How to use

Install the switcher module according to PCB layout recommendations and ensure secure connections to mains and load circuits. Observe correct polarity on DC output and provide appropriate decoupling capacitors or filtering at the load if required by the downstream electronics. Allow for adequate clearance and, if necessary, add heat dissipation measures in cases of continuous near-maximum load. Follow local safety and wiring standards when connecting to mains.

Usage recommendations

Use the PMIC AC/DC module within its rated input and output limits and ensure downstream circuits do not exceed the 5.5 W power budget. For improved longevity and stable performance, avoid sustained operation at maximum output power and provide basic input surge protection in electrically noisy environments.
