![]() ![]() ![]() ![]() reducing the size of the inductor to 270 microHenrys will give 10 milliamperes.ģ. 5252f is a high-performance solar lawn lamp boost control chip, suitable for a 1.2V rechargeable battery powered solar lawn lamp. The current is limited by the L1 inductor, 330 microHenrys will allow 8 milliamperes to go into the LED. It detects when the solar cell is in the dark, and starts up the circuit inside that boosts the 1.2 volts from the battery to over 3 volts, and sends that to the LED. The operating voltage of QX5252 is 0.9V to. It charges the 1.2 volt battery during the day, using power from the 2.5 volt solar cell. QX5252 uses patented technique to realize the LED lights shutdown without flicker when the battery voltage is low. The 5252F integrated circuit does several things. 5252F using patented technology, LED Undervoltage shutdown makes no blinking LED lights. Can be only one external inductor Composition of solar lighting devices. It is driven by a switching circuit, Optical switch circuit, over discharge protection circuit, the internal integration of Short Based diodes and other circuit. 5252F is a solar LED lighting fixtures for ASIC design. ![]()
