Current Control LED Controller
The Document is Applied to: CS6552AEO,CS6552BEO,CS6552EO,CS6552CEO,CS6552DEO
1、General Description
The CS6552 is a high precision primary-side-feedback LED lighting controller which
integrates a 600V high voltage power MOSFET, it achieves 85Vac-265Vac input voltage and
accurate LED current for single-power stage, isolated lighting applications. The constant
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 opto-coupler. It also eliminates the need of loop compensation circuit
while maintaining stability，and increase the reliability.
The CS6552 works in discontinuous 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 feature of CS6552 significantly improves the system reliability and
safety. The CS6552 features over-voltage protection, short-circuit protection, cycle-by-cycle
current limit, VCC UVLO and over-temperature protection. The CS6552 will auto-restart when
protection happens.
