AT6002H
AT6002HZ High Voltage PWM Controller
AT6002HZ High Voltage PWM Controller
General Description
AT6002H is a highly integrated current mode PWM control for flyback converter, optimized for high performance,
low standby power consumption and cost effective offline flyback converter applications.
The AT6002H built-in multiple protection with VCC under voltage lockout (UVLO), VCC over voltage protection
(OVP), VCC clamp, GATE clamp, cycle-by-cycle current limiting (OCP), over load protection (OLP), RT Low Level
Protection(RTLP), RT High Level Protection(RTHP), and leading-edge blanking (LEB) of the current sensing to
prevent circuit damage occurred under abnormal conditions.
The AT6002H also has an X-cap discharge function to discharge the X-cap when the input is unplugged and Brownout
protection function.
The AT6002H is available in an SOP-8L package and require very few external devices for operation.
