MT7853A

Maximizing IC Performance DESCRIPTION The MT7853A is a high-PF, non-isolate LED Driver IC. The floating-ground, high-side BUCK topology makes full wave detection possible. The MT7853A 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 MT7853A integrate 600V MOSFET internally, which simplifies external circuit. The driving capability of the MT7853A is designed to be insensitive to VDD voltage and soft, with MAXIC proprietary technique. It can help to improve EMI performance greatly. MT7853A Non-isolated APFC BUCK LED Driver FEATURES  Single-stage active power factor correction (PFC > 0.90)  High accurate LED current (+/-3%)  Good Line and Load Regulation (+/-2%)  Quasi-Resonant mode (QRM) operation  Various protection schemes.  ...
