American Dahl technology listed new LED bulb drive IC, supply current up to 1.5A

America Dahl Technology (Diodes) listed power supply current maximum 1.5A LED driver IC AL8806". It is provided by the LED driver IC, the maximum supply current of the largest products. Previously, the maximum output current of 1A. Although it also depends on the LED of the forward voltage, but the product can drive up to 8 components from a series of LED lamp string. Suitable for MR16 type LED lamps and input AC / DC 12V general lighting appliances, etc.. The LED driver IC adopts DC-DC buck converter. Integrated switching element (power MOSFET). The on resistance is 0.35 (maximum), and the maximum switching frequency is 1MHz. Therefore, the external passive components can be used to reduce the packaging area of the printed substrate. External components required are four. Input voltage range 30V ~ + in. The maximum supply current of the LED lamp string can be adjusted using an external resistor. The error of output current is 5%. The maximum conversion efficiency is 98%. Dimming is supported by two methods, namely PWM signal duty cycle control method and DC voltage control method.

The current supply of up to 1.5A LED driver IC

The new product has open circuit protection function. Standby current consumption of 350 A (maximum). The work junction temperature range of -40 to 125 C. Package for MSOP-8EP. Price not announced.
