MP4026
Primary-Side-Control,
Offline LED Controller with Active PFC
DESCRIPTION
The MP4026 is a primary-side-control, offline
LED controller that achieves high-power factor
and accurate LED current for isolated, single-
power-stage lighting applications in an FCTSOT
package. It is the next generation of the
successful MP4021A. The proprietary real-
current-control method accurately controls LED
current from primary-side information with good
line and load regulation. The primary-side-control
eliminates the secondary-side feedback
components and the opto-coupler to significantly
simplify LED-lighting-system design.
The MP4026 integrates power-factor correction
and works in boundary-conduction mode to
reduce MOSFET switching losses.
The MP4026’s multiple protection features
greatly enhance system reliability and safety.
These features include over-voltage protection,
short-circuit protection, primary-side over-current
protection, brown out protection, cycle-by-cycle
current limiting, VCC under-voltage lockout, and
auto-restart over-temperature protection.
