MT7830A - Non-isolated APFC BUCK LED Driver

General 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.

Key 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.

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.
