A SMPS viper12 a quality control sample for the use of integrated LED lighting can be used in different applications or .. have a nice design sizes quite small
DC output: 12 mA VDC/500
Efficiency: 75% typical
Input voltage: 90-264VAC 50-60 Hz
Dimensions: 57 x 49 x 32 mm
This network is designed for the assembly in sub-cleaning Junction boxes. With its output of 6 W (12 VDC/500 mA) can be almost any standard Power Supply through this discreetly in the wall installable version replaced. Whether as a power supply for surveillance cameras, wireless video transmission systems or small fan installation — the application are no limits.
VIPer12A SMPS Circuit
SMPS Controllers (Switch mode power suppl) IC 2, the circuit is quite clearly. The at the terminals supplied from KL 1 230 V AC is protected by the fuse, guided on the bridge rectifier. This makes the 230 VAC a DC voltage of about 320 V. This DC voltage is applied via the transformer TR 1 to the drain of the Switching regulator viper12a ICs. This IC contains all essential stages of a switching power supply. Then run the internal Oscillator which oscillates at 60 kHz. Also, the other internal stages active and the power MOSFET begins to switch. Limiting the drain Current is adjusted via an internal control circuit
