LED lighting industry insiders know that LED driver power is a power converter that converts the power supply into a specific voltage and current to drive LED illumination. It seems to be inconspicuous in the design of the entire lighting product, but it is extremely critical. To meet the needs of the market, reducing costs, improving efficiency and reliability has become the most sought-after goal of every enterprise. As a new generation of light source, the LED's plasticity on the light source is a natural development for many LED manufacturers. Nowadays, according to the development of the market, the LED bulb power supply has entered the market in a logical way. The power supply will all be isolated by non-isolated replacement.

The current mainstream 3W drive power supply in the market:
3W LED bulbs are one of the largest consumer demand markets. The current mainstream solution is 3x1W, each lamp is 3.3V/300mA, and the load is formed by three lamp bead series. The output load is 10V/300mA. Since the grid voltage is rectified and the output load voltage is quite different, the most suitable way is to drive the buck through the flyback isolation. However, the isolation circuit has a complicated structure, many devices, high cost, low efficiency, low reliability, and is not suitable for mass production. In contrast to the isolated circuit, the non-isolated circuit has a simple circuit, uses fewer devices, is small in size, has lower cost, and is more efficient. As the market demands cost and efficiency, non-isolated circuits are on the stage in the field of low-power LED drivers.
