High Power LED Driver
Preliminary
PT6904
DESCRIPTION
PT6904 is a constant-current LED driver IC utilized constant frequency, controls buck, boost or buck-boost switch converter. In each control mode, PT6904 adopts the inductance current continuous conduction, peak current control mode and the feedback of the output current. It’s controlled by the internal transconductance operational amplifier and external adjustable slope pensation, it is able to gain the high precision output current in closed loop. The typical functions of PT6904 such as UVLO (Under Voltage Lockout), input current limit, open LED protection,...
