MP4030A
TRIAC-Dimmable, Primary-Side-Control
Offline LED Controller with Active PFC
DESCRIPTION
The MP4030A is a TRIAC-dimmable, primary-
side-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 real-
current-control method can accurately control the
LED current using primary-side information. It
can significantly simplify LED lighting system
design 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), short-
circuit protection (SCP), primary-side over-
current protection (OCP), supply-pin under-
voltage 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.
