MP4021GS 原边反馈单极PFC

The MP4021 is a primary-side-control offline LED lighting controller that achieves high power factor and accurate LED current for single-power stage, isolated lighting applications. The proprietary real current control method accurately controls the LED current from the primary side , and therefore significantly simplifies the LED lighting system design by eliminating the secondary side feedback components and the optocoupler.

The MP4021 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 to provide a high efficiency solution for lighting applications.
The multi-protection features of MP4021 significantly improves greatly enhance the system reliability and safety. The MP4021 features over-voltage protection, short-circuit protection, cycle-by-cycle current limit, VCC UVLO and auto-restart over-temperature protection.
