Diodes Incorporated announced the availability of the versatile dimming input controller for offline LED lamps. AL8116 works with three types of dimmer signal formats:
It converts these to a PWM output signal which can easily be used to provide an isolated dimming control via an opto-coupler to the primary side LED driver.
|AL8116 Typical Application Circuit.|
The AL8116 has a wide supply voltage range from 10 V to 56 V. The AL8116 Output Duty Cycle accuracy is typically ±2.5% and its minimum Output Duty cycle can be set through a CLAMP pin resistor.
The AL8116 has an internal overtemperature protection (OTP) and it is available in the SOT26 package.
