Maximizing IC Performance
MT7830A
Non-isolated APFC BUCK LED Driver
DESCRIPTION
The MT7830A is a high-PF, non-isolate LED Driver IC. The floating-ground, high-side BUCK topology makes full wave detection possible. The MT7830A 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 driving capability of the MT7830A is designed to be insensitive to VDD
voltage and soft, with MAXIC proprietary technique. It can help to improve EMI performance greatly.
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. Power-on soft-start Compact package: SOP8
APPLICATIONS
E27/PAR30/PAR38/...
