Gain design. Through the LTBGAIN pin it is possible to modify the slope of the LTB
Ramp in order to modulate the entity of the LTB response once the LT has been
detected. In fact, the response depends on the board design and its parasites requiring
different actions from the controller.
Connect RLTBGAIN to SGND using the following relationship in order to select the
default value (slope of the LTB ramp equal to 1/2 of the OSC ramp slope).
Where FSW is the selected switching frequency (in kHz).
LTB Technology design tips.
–
Decrease RLTB to increase the system sensitivity making the system sensitive to
smaller dVOUT.
–
Increase CLTB to increase the system sensitivity making the system sensitive to
higher dV/dt.
–
Decrease RLTBGAIN to decrease the width of the LTB pulse reducing the system
ring-back or vice versa.
