OB3328QP OB3328 SOP16

The OB3328 provides a high degree of design
flexibility by offering great programmability for key
parameters which include operating frequency,
striking frequency, striking time, burst dimming
frequency, soft-start time, and soft on/off time for
burst dimming.
The OB3328 offers variable dimming modes and
selectable dimming polarity1. Both internal burst
and external low frequency PWM (LPWM)
dimming methods are available for a wide range of
dimming control (10% to 100%). Furthermore,
analog dimming is provided through external DC
input control to achieve 40% to 100% dimming
range.
The highly integrated OB3328 provides complete
protection features covering IC under voltage
lockout (UVLO), output over voltage protection,
and lamp fail safe function
