MP4021A

Primary Side Control

Offline LED Controller with Active PFC

DESCRIPTION

The MP4021A is a primary-side–control offline

LED lighting controller that achieves high power

factor and accurate LED current for isolated

single-power-stage lighting applications in a

single SOIC8 package. The proprietary real-

current control method accurately controls LED

current from primary-side information. Eliminating

the secondary-side feedback components and

the optocoupler significantly simplifies the LED

lighting system design.

The MP4021A integrates power factor correction

and works in boundary conduction mode to

reduce the MOSFET switching losses.

The extremely low start-up current and quiescent

current reduces the total power consumption and

provides a high-efficiency solution for lighting

applications.

The multi-protection features of MP4021A greatly

enhance system reliability and safety. The

MP4021A features over-voltage protection, short-

circuit protection, cycle-by-cycle current limiting,

VCC UVLO, and auto-restart over-temperature

protection.

FEATURES

• Real current control without secondary-

feedback circuit

• Typical ±1.5% load regulation

• Unique architecture for superior line

regulation

• High power factor≥0.9 over universal input

voltage

• Boundary conduction mode improves

efficiency

• Ultra-low (20µA) start-up current

• Low (1mA) quiescent current

• Input UVLO

• Cycle-by-cycle current limit

• Over-voltage protection

• Short-circuit protection

• Over-temperature protection

• Available in an SOIC8 package

APPLICATIONS

• Solid-state lighting

• Industrial and commercial lighting

• Residential lighting
