PT6913A
DESCRIPTION
PT6913A/B is a special current regulator to drive HV
LED. Few external components design is very flexible
in many compact size applications. The simple driving
topology will improve power factor, efficiency. EMI
issue will be avoided with this linear control.
PT6913A/B supports maximum 400V input voltage
that ensures the high reliability for HV LED lighting.
LED open/short is protected by PT6913A/B. The high
voltage will be absorbed by PT6913A/B itself. LEDs
will never face high voltage problem.
PT6913A/B also provides temperature attenuation
function. When internal junction temperature is higher
than 130, PT6913A/B will decrease the output
current linearly. The output current will be zero when
internal junction temperature reaches 150 . This
protection method effectively avoids the flicker
problem during abnormal environment temperature.
APPLICATIONS
LED Bulb
LED Tube Lamp
Compact Size LED Lighting
