The MP4030A is a TRIAC-dimmable, primaryside-control, offline LED lighting controller with active PFC. It can output an accurate LED current for an isolated lighting application with a single-stage converter. The proprietary realcurrent-control method can accurately control the LED current using primary-side information. It can significantly simplify LED lighting systemdesign by eliminating secondary-side feedback components and the optocoupler.
The MP4030A implements power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses.
The MP4030A has an integrated charging circuit at the supply pin for fast start-up without a perceptible delay.
The proprietary dimming control expands the TRIAC-based dimming range.
The MP4030A features multiple protections including over-voltage protection (OVP), shortcircuit protection (SCP), primary-side overcurrentprotection (OCP), supply-pin undervoltage lockout (UVLO), and over temperature protection (OTP). All of which not only simplifies circuit design but also enhances system reliability and safety greatly. All fault protections feature auto-restart.
The MP4030A is available in an 8-pin SOIC package.
