MT7835

Non-isolated APFC BUCK LED Driver

DESCRIPTION
The MT7835 is a high-PF, non-isolate LED Driver IC. The floating-ground, high-side BUCK topology makes full wave detection possible. The MT7835 works in QRM mode, which improves both of efficiency and EMI performance. Selectable maximum period control is integrated, such that flick can be eliminated while enough demagnetization time is guaranteed.
Various protections such as OVP, OCP, OTP, etc, are embedded to improve reliability. The MT7835 integrate 550V MOSFET internally, which simplifies external circuit.
The driving capability of the MT7835 is designed to be insensitive to VDD voltage and soft, with MAXIC proprietary technique. It can help to improve EMI performance greatly.
