General Description

The iML8692CFA is an LED current controller with line regulation compensation for operating over a wide alternative current (AC) voltage source range and with active load controller for phase cut dimmable function. It can drive an external N-channel power MOSFET to regulate the current flowing through a high voltage (HV) LED string and provide the holding current for the phase cut dimmer.

The application of the iML8692CFA is configured in series with an LED string, working as a constant current sink with over voltage protection (OVP), over temperature protection (OTP), and line regulation compensation. Active load function is included to improve the phase-cut

dimming performance. It is suitable for applications with a rectified AC voltage source.The PCB layout is also very flexible to meet various shape requirements. It is especially suitable for replacingincandescent light bulb and linear type fluorescent lamp.
