Circuit Configuration to Decrease
Output Voltage
With an external resistor connected between the TRIM
and V
O
(–) pins (R
adj-up
), the output voltage set point
(V
O, adj
) increases (see Figure 6). The following equa-
tion determines the required external resistor value to
obtain an output voltage from V
O, nom
to V
O, adj
:
where R
adj-up
is the resistance value connected
between TRIM and V
O
(–), and the values of G, H, K,
and L are shown in the following table.
The combination of the output voltage adjustment
and the output voltage regulation cannot exceed 110%
of the nominal output voltage between the V
O
(+) and
V
O
(–) terminals.

Circuit Configuration to Increase Output
Voltage
The SMLW010 Power Modules have a fixed current-
limit set point. Therefore, as the output voltage is
adjusted down, the available output power is reduced.
In addition, the minimum output current is a function of
the output voltage. As the output voltage is adjusted
down, the minimum required output current can
increase (i.e., minimum power is constant). As the out-
put voltage is adjusted up, the output power should be
held constant (maximum load current decreases).
Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, almost entirely independent of the primary regu-
lation loop, that monitors the voltage on the output
terminals. This control loop has a higher voltage set
point than the primary loop (see Feature Specifications
table). In a fault condition, the overvoltage clamp
ensures that the output voltage does not exceed
V
O
, clamp, max
. This provides a redundant voltage-control
that reduces the risk of output overvoltage.
