Power Integrations Switching controller IC SMD-8B (7-PIN)

Highly-efficient switch controller IC with low energy consumption. Fully integrated auto restart to detect a short circuit or open regulation loop. Programmed under-voltage prevents spikes during shut-on and shut-off. EcoSmart. Drastically simplified EMC filtering with frequency jitter. 132 kHz switch frequency allow inexpensive EF12.6 or EE13 cores with transformer. Easy switch design. Fitting design kits included. Power input P at zero load < 50 mW with auxiliary coiling; < 250 mW without auxiliary coiling @ 265 VAC-input.
