Non-isolated segmented switch dimming IC solution makes LED lighting more energy efficient
Ordinary household wall switch can be segmented switch for brightness segmentation adjustment, only 50% brightness can be turned on during the day, 100% brightness can be turned on at night, and 20% brightness can be turned on when watching TV, without increasing In the case of power costs, the H4102 can make LEDs more energy efficient and more flexible to use.
The H4102 is a simple non-isolated segmented switch dimming IC solution with adjustable brightness including 100%, 50%, and 20%. No need for a single-chip microcomputer, the periphery is the same as ordinary non-dimming, the cost is not increased, and the dimming is the same as the non-dimming chip pin.
H4102 input voltage 85-265V, no stroboscopic, output power can be up to 60W, output current can be up to 420mA, can be used for wide voltage and no stroboscopic, universal.
characteristic
Adjusting the current without changing the inductance, only need to adjust the resistance, can be common inductance, stocking is very convenient, with ultra-high performance, ultra-high load regulation, ultra-high linearity adjustment rate, high current constant accuracy of 1%, compatible with 4-8 strings With ultra-stable no-load voltage, it solves the shortcomings of changing the inductance of the chip on the market and changing the no-load voltage, and has various protections;
Output multiple protections such as over temperature protection, over voltage protection, and open circuit protection;
The high temperature does not drop the current, and the 80 degree environment ensures that the current is less than 1 mA, and the constant current is truly achieved. The high temperature is protected by the current reduction, and the process does not flash;
High synchronism, the unique control technology inside the chip can ensure the synchronization of the lamp group. The no-load voltage is adjustable to prevent the no-load voltage from being too high to burn the lamp bead;
Single-chip control chip, no need for single-chip control to do back-end control. Ultra-simple periphery.
