Output Voltage Setting with Adaptive Loop
The equations for calculating ROS and RCD to set a VTM output
voltage are:
93100
ROS =
( VL 0.8395 ) – 1

RCD =

ROS
VL = Desired load voltage
VOUT = VTM output voltage
K = VTM transformation ratio
(available from appropriate VTM data sheet)
Vf = PRM output voltage, the Factorized Bus (see Figure 16)
RO = VTM output resistance
(available from appropriate VTM data sheet)
IL = Load Current
(actual current delivered to the load)
Output Voltage Trimming (optional)
After setting the output voltage from the procedure above the output
may be margined down (26 Vf min) by a resistor from SC-SG using this
formula:
Rd
Ω =
10000 Vfd
Vfs - Vfd
Where Vfd is the desired factorized bus and Vfs is the set factorized bus.
A low voltage source can be applied to the SC port to margin the load
voltage in proportion to the SC reference voltage.
An external capacitor can be added to the SC port as shown in Figure 16
to control the output voltage slew rate for soft start.
