MT7832A

Maximizing IC Performance DESCRIPTION The MT7832A is a high-PF, non-isolate LED Driver IC. The floating-ground, high-side BUCK topology makes full wave detection possible. The MT7832A works in Quasi-Resonant mode (QRM), 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 MT7832A integrate 550V MOSFET internally, which simplifies external circuit. The driving capability of the MT7832A is designed to be insensitive to VDD voltage and soft, with MAXIC proprietary technique. It can help to improve EMI performance greatly. MT7832A 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 protectio...
