SS/LTB/AMD connections when using LTB™ gain < 2

When using LTB™ gain <2, the equivalent RSSOSC resistance is composed by the sum of

R1+R2) because until the soft-start is not finished the Q transistor is OFF (See Figure 18).

Figure 18.

SS/LTBG/AMD connections for INTEL mode, when using LTB™ gain < 2

where TSS is the time spent to reach the programmed voltage VSS and RSSOSC the resistor

connected between SS/LTBG/AMD and SGND (RSSOSC = R1 + R2) in kΩ.
