DX6210
DX6210 is primary side offline LED lighting regulator manufactured by DX Semiconductor.
Description
The DX6210 is a single-power stage, isolated and
SOT23-6 primary side offline LED lighting regulator which achieves high power factor . The proprietary
KONGSON real-current control method can control the LED current accurately from the primary side information . It can significantly simplify the LED lighting system design by eliminating the secondary side feedback ponents and the opto-coupler . The DX6210 integrates active power factor correction and works in Quasi Resonance mode (QRM) in order to reduce the MOSFET switching losses to provide a high efficiency solution for lighting applications. The external programmable line voltage pensation provides a more precise output current throughout the universal AC input voltage range. The leading edge blanking circuit on the CS/FB input removes the signal glitch and results in reduced external ponents and system cost.
The multi-protection features of DX6210 greatly enhance the system reliability and safety . The DX6210 features
VDD and output over voltage protection; output short circuit protection, cycle-by-cycle current limit and secondary peak current protection on CS pin, VDD UVLO and auto-restart and over-temperature protection. The driver output voltage is clamped at 18V to protect the external power MOSFET .
