DESCRIPTION
The PT5622 is an electronic ballast controller IC
intended for dimming product with ordinary switch. The
features of the controller IC include negative-feedback
closed-loop control of the lamp current, programmable
preheat time and preheat frequency, low start-up
current, precise oscillating frequency and easy
applications. PT5622 is available in both DIP16/SOP16
packages.
APPLICATION
• Adjustable to various types of fluorescent
lamps/CFLs
FEATURES
• Electronic ballast IC with dimming function using
ordinary switches
• Integrated MCU
• Negative-feedback control of the lamp current,
supporting low luminance ignition
• 2/3-level selection available for low to high or high
to low luminance dimming mode
• Programmable preheat time
• Programmable preheat frequency, sweeping
frequency ignition
• Programmable delay time from switch-off to reset
state
• Programmable delay time from switch-on to
preheat mode
• Fixed dead time
• Supporting DIP16/SOP16 packages
