Overview

Maximizing IC Performance DESCRIPTION The MT7834A is a high-PF, non-isolate LED Driver IC.
The floating-ground, high-side BUCK topology makes full wave detection possible.
The MT7834A 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 MT7834A integrate 550V MOSFET internally, which simplifies external circuit.
The driving capability of the MT7834A is designed to be insensitive to VDD voltage and soft, with MAXIC proprietary technique.
